ConvaTec DuoDerm CGF Border Hydrocolloid Dressing — Control Gel Formula, Foam Border, 5 Sizes Including Triangle

Proprietary Control Gel Formula. Wide foam border — no tape needed. Two triangle shapes for hard-to-dress anatomy. ConvaTec DuoDerm CGF Border is a sterile, self-adhesive hydrocolloid wound dressing built on ConvaTec's proprietary Control Gel Formula (CGF) — a unique hydrocolloid composition of pectins, gelatins, sodium carboxymethylcellulose, and elastomers that is clinically distinct from standard hydrocolloid dressings. When in contact with wound exudate, the CGF matrix converts to a soft, cohesive gel mass that creates and maintains an optimal moist healing environment, supports autolytic debridement, and allows for low-trauma dressing removal with minimal disruption to healing tissue. The outer polyurethane foam border provides a wide adhesive perimeter that secures the dressing in place without any supplemental tape — even in difficult anatomical locations. Available in five sizes including two anatomically shaped triangle dressings designed specifically for hard-to-dress body contours.

✔ Proprietary CGF Formula — Pectins, Gelatins, CMC & Elastomers    ✔ Wide Foam Border — Tape-Free Secure Fixation    ✔ Bacterial & Viral Barrier (HBV & HIV)    ✔ Hard-to-Dress Area Capability    ✔ Triangle Shapes for Contoured Anatomy    ✔ Latex-Free

Contraindications: Not indicated for heavily exudating wounds — for high-drainage wounds a foam or alginate primary dressing is more appropriate. Not for use on infected wounds without concurrent clinical management. Not for third-degree burns or surgical implantation.


The CGF Formula — What Makes DuoDerm Different from Standard Hydrocolloid

Standard hydrocolloid dressings are built primarily on a carboxymethylcellulose (CMC) base — a single hydrogel-forming polymer that absorbs exudate and swells into a gel at the wound surface. DuoDerm CGF uses a more complex, proprietary formula that combines four distinct components: pectins, gelatins, CMC, and elastomers. Each component contributes a different mechanical and functional property to the finished dressing.

  • Pectins — plant-derived polysaccharides that provide initial gel-forming capacity and contribute to the dressing's ability to absorb a broad spectrum of wound exudate components, including proteins and inflammatory mediators
  • Gelatins — protein-based polymer that adds structural body to the gel mass as it forms, helping the dressing maintain a consistent, cohesive gel that doesn't thin out or fragment during the wear period
  • Sodium Carboxymethylcellulose (CMC) — the primary hydrophilic absorbent polymer, responsible for moisture uptake and the conversion of the hydrocolloid matrix from solid to gel state on contact with wound exudate
  • Elastomers — rubber-like polymers that provide the dressing matrix with flexibility and conformability, allowing the dressing to move with the body and maintain contact with wound surfaces that change shape during activity

The result of this four-component formula is a gel mass that forms more completely, holds together more cohesively, and releases from the wound surface more cleanly than single-polymer hydrocolloids. The gel forms a soft, moist interface between the wound surface and the dressing that supports autolytic debridement — the body's own enzyme-driven process of breaking down necrotic and sloughy wound tissue — while protecting granulation tissue from trauma at dressing change. The dressing also provides a continuous bacterial and viral barrier, with documented effectiveness against HBV and HIV.

  • Multi-component CGF formula — more complete gel formation than single-polymer hydrocolloids
  • Cohesive gel mass — holds together cleanly, minimal residue in wound bed at dressing change
  • Creates and maintains optimal moist wound healing environment throughout wear period
  • Supports autolytic debridement — gel environment activates the body's own debridement enzymes
  • Bacterial and viral barrier — documented protection against HBV and HIV throughout wear
  • Occlusive construction — isolates wound from external contamination and environmental bacteria
  • Low-trauma removal — cohesive gel lifts away without disrupting healing tissue or granulation bed

The Foam Border — Why It Matters for Hard-to-Dress Areas

DuoDerm CGF Border's outer polyurethane foam border is not simply a convenience feature — it is the structural reason this dressing is specifically appropriate for hard-to-dress anatomical locations. Standard hydrocolloid dressings rely on the adhesive underside of the hydrocolloid pad itself to maintain wound contact. On flat, stable wound sites this works well, but on curved or mobile surfaces — the heel, elbow, shoulder, sacrococcygeal area, between the toes, or any joint — the pad edge experiences repeated mechanical stress from movement and contour changes that causes progressive edge lift and dressing loss.

The wide foam border extends beyond the hydrocolloid pad on all sides, distributing the adhesive contact area across a much larger perimeter of healthy periwound skin. The foam material is flexible and compressible — it conforms to body contours that would cause a rigid border to peel — and its adhesive properties remain stable across the range of motion experienced at joint and contoured wound sites. This allows DuoDerm CGF Border to maintain secure, tape-free fixation in locations where standard bordered or non-bordered hydrocolloids routinely fail prematurely.

  • Wide foam border — distributes adhesive hold across a larger perimeter than hydrocolloid-only dressings
  • Flexible, compressible foam — conforms to curved and mobile anatomical surfaces without peeling
  • No supplemental tape required — the border is the fixation system
  • Designed for hard-to-dress areas — heels, elbows, sacrum, joints, and contoured body surfaces
  • Extended wear time — secure border prevents the premature edge lift that cuts short standard hydrocolloid wear

Square vs. Triangle Sizes — Which Shape Is Right?

The three square sizes (187970, 187971, 187972) are the standard choice for most flat, accessible wound surfaces — pressure injuries over flat bony prominences, diabetic foot ulcers on a flat plantar surface, surgical wounds, and venous ulcers on a flat medial leg surface. Square dressings provide the most efficient coverage area per dressing and are the most common configuration for general wound management.

The two triangle sizes (187973, 187974) exist specifically for wound locations where square geometry fails to conform — most notably the sacral/coccygeal area and the heel. These are the two most common high-risk pressure injury sites in clinical practice, and they are also the sites where standard square dressings most often fail early due to the curved, multi-plane anatomy and the mechanical stress generated by positioning changes in bed-bound patients. The triangle shape follows the natural contour of the sacrum and the posterior heel, placing the adhesive foam border along anatomical lines rather than across them, which dramatically improves dressing conformity, edge seal, and overall wear time at these critical sites.

  • 187970 — 2½" x 2½" Square: Small wounds, early-stage pressure injuries, superficial wounds on flat compact surfaces
  • 187971 — 4" x 4" Square: Standard size — the most commonly used; typical pressure ulcers, diabetic foot ulcers, venous leg ulcers, donor sites, and burns of average dimension
  • 187972 — 6" x 6" Square: Larger wounds requiring broader coverage — extensive pressure injuries, large donor sites, wider venous ulcers, or any wound where a 4x4 would not provide adequate margin coverage
  • 187973 — 4" x 5" Triangle: Smaller sacral and heel wounds — Stage II–III sacral pressure injuries of moderate size and posterior heel ulcers where the triangular shape provides superior anatomical conformity
  • 187974 — 6" x 7" Triangle: Larger sacral and heel wounds — Stage III–IV sacral pressure injuries and larger heel ulcers requiring maximum triangle coverage; also appropriate for any contoured wound site where the larger triangle footprint provides better coverage than the 4x5

DuoDerm CGF Border vs. DuoDerm CGF Sterile (Non-Bordered)

DuoDerm CGF is available in two configurations — the Border version (this product) and the non-bordered Sterile Dressing version. Both share the identical CGF hydrocolloid formula and provide the same wound healing environment. The distinction is entirely in fixation:

  • CGF Border (this product): Self-contained — the foam border is the fixation system. No tape, no secondary dressing needed for most wounds. Best for hard-to-dress areas, home care patients, and any setting where simplicity and one-step application are priorities.
  • CGF Sterile (non-bordered): Requires tape or a secondary dressing for fixation. Better for patients with adhesive sensitivity across a large periwound area, wounds where the clinician needs custom fixation, or wounds being used under compression bandaging where an outer border would interfere with wrap application.

Simple and not Drama claim process.
’ve had Asurion coverage for a couple of years and never needed to use it until recently, when my pool salt cell (less than two years old) stopped working. I had purchased it with an Asurion protection plan, so I contacted them to start a claim. The process was simple and straightforward to follow. In the end, they honored the plan and covered the cost of my salt cell based on the value when I originally bought it. They issued me a gift card that I could use on Amazon for that amount. While prices have gone up and a new cell now costs about $200 more, it was still definitely worth having the coverage. Overall, I’m satisfied with how the claim was handled.

Love this protection plan
Quick and easy. My daughter's cracked her screen on her phone, as soon as it happened I went on the app, filed the claim. Ten minutes later I received the email with the shipping lable. The following day I dropped the phone off at ups and 4 hours later I received the digital gift card. Ive filed several claims since getting the protection plan and with four kids its definitelysomething im glad to have especially since i dont have to buy a protectionplan for each item now. I have filed claims for electric scooter the stoped working for no reason, my son's phone stopped charging, my oldest daughter cracked her phone screen, my son's video game controllers up and died and each time it was quick and easy and no fuss

Don't waste your money - these people will not help you
On March 9th 2024, I purchased a MCombo Lift Chair costing $785. On the same day, through the same Amazon account (my PERSONAL account since I also have a business account), I purchased an Asurion Complete Protect policy at the cost of $16.99 per month plus taxes. About one month ago, a problem arose with the chair that required me to make a claim using the "Complete Protect" policy that I had purchased for that very item. The claim was initiated on January 1st, 2025 - On January 3rd, I received an email asking me for photographs showing the damage for which I was making a claim. I sent those photographs via email to the address provided on January 6th. On January 27th, having not received ANY response from Asurion, I contacted them via phone and was told that my purchase had been made with a business account, that it was being used for business purposes, and was therefore not covered. I assured the Asurion Representative that it was most certainly not a business use, and that the chair that I was claiming for had been purchased because I had extensive shoulder surgery done that made it impossible to get in and out of bed. After speaking (unsuccessfully) with the Asurion Rep, I then contacted Amazon Customer Service. I spoke with an Amazon Customer Service Representative on the phone who confirmed that I had in fact used my personal account to purchase the chair and the Asurion Complete Protect policy. That representative went on to send a message to Asurion on my behalf confirming that the purchase was for personal use and not business use. Asurion responded, asking me to call them with the order number for the Asurion purchase. The number I gave was the exact same order number on my order history, however, the Asurion Rep could not find it. I was finally able to discover that the order number in Asurion's system was entirely different and isn't even in the same format as an Amazon order number. Upon the Asurion representative finding my plan, she informed me that the chair was listed as being purchased for business use (despite Amazon confirming that it was NOT) but that I should give them "a couple of business days" to resolve the issue. Five business days later, still no response and so I called them again (Yesterday - February 1st 2025)... Lo and behold, I got the same crap yet again... the purchase was listed as business use and was therefore being denied, but she promised to remove the business use commentary and put the claim through again. Today, February 2nd, I called Amazon yet again to escalate and had to call THREE times because the first two calls resulted in me finally being connected to an Asurion representative (two different reps) and each time, the Asurion representative hung up the phone as soon as my name was mentioned. It has become clear to me that the Asurion "Complete Protect" policy is a SCAM - they will NOT take care of your issue, regardless of how long you've been paying. I have been paying every month since March 9th last year - so they've received over $170 from me thus far, with zero other claims, and if I am able to cancel right now, I will only receive $16.99 back. All I want, is the chair that I purchased the policy for coverage of, to be repaired or replaced. Asurion are NOT helping, and are actively avoiding contact. At this point, I am considering legal action against Asurion for fraud - perhaps even a Class Action. I'll wait and see if my issue gets resolved within the next 10 days or so.

Asurion is AWESOME!
Ok, so let me start with the fact that you should NOT waste your time calling Amazon's customer service if you think you have a claim under Asurion's monthly protection plan. CALL ASURION! I wasted almost an hour with Amazon representatives that have absolutely no training in how the Asurion plan works, or even any idea if my item was covered. In fact, they told me the mechanized chair I purchased under the plan wasn't covered! Finally, my call got escalated to a manager who was just as clueless about my coverage, but had the best idea ever... call Asurion! The smartest thing I did that morning was hang up with Amazon, and reach out to Asurion as I should have done in the first place. Dealing with Asurion's customer service, after my Amazon call, was like being elevated to VIP status! 😄 Asurion's rep nicely took all my info, including the chair's purchase date and order number. Then they asked that I upload a couple of pictures of the product, along with a written description of the malfunction I had mentioned over the phone. This is where it gets really good. They told me they'd review the claim to determine if they'd send a repair specialist or reimburse me the cost of the item. In less than 48 hours, they determined that a payout was in order, and sent me an email that included an Amazon gift card for the total cost of the item minus the taxes I had paid, which I loaded directly into my Amazon wallet. Apparently, Asurion does not include the purchase taxes in their coverage. But, I can live with that. All in all, Asurion's claims division get a double thumbs up 👍🏽👍🏽, and the company gets big ups from me for not only standing behind their protection plan, but doing so expeditiously! Special note: If you buy a lot of stuff from Amazon, and have Asurion's monthly protection plan, scroll the item listing before pulling the trigger on your purchase... you need to see the green streamer that indicates your product is protected by the plan. If you don't see that, check to see if there are alternative products that might be covered. There are very few electronic or high ticket items that aren't covered, but looking for that green banner in the item description that says it's covered is key to foregoing any future headaches.
