Claims13
A resilient, non-porous, significantly non-absorbent pressure-sensitive adhesive tape consisting essentially of a uniform substrate of open-celled, high density, flexible, resilient polyurethane foam impregnated with an impregnant consisting essentially of a cured polychloroprene elastomer that is invested throughout said substrate and a cured pressure-sensitive adhesive coated upon said substrate, said substrate having a thickness of up to 35 mils.
A resilient, non-porous, pressure-sensitive adhesive tape consisting essentially of a substrate of open-celled, flexible, resilient polyurethane foam having a density of from 25 pounds per cubic foot to 60 pounds per cubic foot impregnated with an impregnant consisting essentially of a cured polychloroprene elastomer, said substrate being coated with a cured pressure-sensitive adhesive;
- and having a thickness of up to 35 mils.
