  • Rubber
CONT

Butyl Gauntlet Glove Box Gloves. ... The glove is made of a Butyl layer. The elastomer is an isoprene-isobutylene copolymer rubber.

CONT

Product Name: G&E Blended Butyl. Chemical Name: blend of isoprene/isobutylene copolymer. Chemical Family: Poly(alkene).

CONT

A transdermal therapeutic system(TTS) comprising an active substance which is sensitive to hydrolysis, and having a layer-like structure comprising a backing layer impermeable to moisture and active substance, a matrix comprising the active substance, and optionally a protective layer covering the matrix is characterized in that the matrix contains a water-binding component [which] may be of mineral or non-mineral nature. One embodiment further provides for the matrix or one of its layers to contain an acrylic-acid ester copolymer, a polyisobutylene, an ethylene-vinyl-acetate polymer, or styrene-isoprene block polymer, or a synthetic isoprene-isobutylene copolymer, or a hot-melt adhesive.
