A NEW, UNIQUE THERMOPLASTIC ELASTOMER WITH ENHANCED PROPERTIES

摘要

A new polyolefin-polyacrylate elastomer based thermoplastic elastomer has been introduced on the market. It is produced by a method called solid state grafting and it can be further modified by compounding. Rigid polypropylene or polyethylene copolymer constitutes a continuous phase in which soft crosslinked polyacrylate elastomer is dispersed. The elastomer is a fundamentally new concept offered to compounding companies and the present three base polymer grades provide new alternatives with their moderate price and unique properties. The chlorine-free elastomer offers excellent oil and gasoline resistances combined high flex resistance and good weather resistance. It has also good adhesion to paints, polyethylene, and polypropylene, and the surface smoothness is excellent.
