MED 5644

Single-Coated Foam

MED 5644 is an alternative to PVC foam. It is an ecofriendly, single-coated tan foam that looks, feels and functions like a traditional PVC foam. This new foam is not made with natural rubber latex and is non-irritating to the skin as it is made using a biocompatible acrylic adhesive. The product is also offered with the option to include perforation to increase the product’s breathability.
