New Transparent and Low-Tensile Set Biocompatible Thermoplastic Elastomers: Poly(siloxane) Modified Poly(olefin) Block Copolymers
Chapter
Abstract
New types of silicone-modified thermoplastic elastomers (TPEs) which exhibit improved optical clarity and compression-tensile set behavior have been developed based on styrene-ethylene/butylene-styrene (SEBS) block copolymers. Poly(alkyl)poly(siloxanes) have been used as alloying modifiers to enhance compatibility and transparency of the silicone-SEBS blends. These TPE blends exhibit a unique balance of physical properties and desirable thermoplastic processing qualities. Their silicone-like surface characteristics make them of special value for many medical device applications.
