MED 6650

Double-Coated Foam

MED 6650 is a double-coated, white, soft, conformable, thin polyethylene foam with our patented moisture resistant WetStick™ adhesive on the mounting side and a solventless acrylic adhesive on the laminating side. This product’s unique WetStick™ adhesive is designed to provide high initial tack and high adhesion to the skin, even when exposed to moisture during prolonged procedures and for ease of removal from the patient’s skin. The heavy-duty liner is ideal for kiss cutting, die cutting and converting.


Typical Application

Designed for ostomy flanges and fixation devices.
