Abstract
Tapes including an elastomeric backing layer having two major surfaces, wherein the backing layer includes a high temperature resistant elastomer (e.g., a high consistency silicone rubber elastomer), and a pressure sensitive adhesive layer, wherein the pressure sensitive adhesive layer comprises a silicone pressure sensitive adhesive.
Claims15
A tape comprising:
- an elastomeric backing layer having two major surfaces, wherein the backing layer comprises a high consistency silicone rubber elastomer;
- a flexible intermediate layer disposed on a first major surface of the backing layer, wherein the flexible intermediate layer comprises a cured epoxy-based material;
- and
- a pressure sensitive adhesive layer disposed on the flexible intermediate layer, wherein the pressure sensitive adhesive layer comprises a silicone pressure sensitive adhesive;
- wherein the tape has a tensile elongation of at least 100%, according to the Tensile Properties—Method B Test.
