Abstract
A cellular rubber body protection material having an inner layer of porous expanded PTFE. It is useful as, for example, a wet suit or orthopedic brace, offering improved wearing comfort and reducing allergenic reactions in comparison to conventional cellular rubber body protection materials.
Claims6
A body protection material consisting essentially of a laminate of:
- a) an outer layer of substantially air impermeable cellular rubber;
- and
- b) an inner layer of porous expanded polytetrafluoroethylene wherein the inner layer is bonded directly to the outer layer with an adhesive selected from the group consisting of silicone adhesives, polyurethane adhesives, acrylic adhesives and rubber-based adhesives.
A body protection material according to claim wherein the coating is between the outer layer of cellular rubber and the inner layer of porous expanded polytetrafluoroethylene and serves as the adhesive between the outer layer and the inner layer.
