Total Finaprene® 401 Styrene-Butadiene TPE Copolymer  (discontinued **)
Categories: Polymer; Thermoplastic; Elastomer, TPE; Styrenic TPE; Styrene-Butadiene

Material Notes: Styrene-Butadiene Copolymer

Description: Finaprene® 401 is a thermoplastic elastomer type radial styrene-butadiene block copolymer (SBS). It has a moderate molecular weight, thus provides excellent cohesive and elastic properties to the modified road binder.

Applications: Thanks to its very high crumb porosity Finaprene® 401 is used for the road binder modification. Its crumb shape, along with the medium molecular weight confer excellent properties along with an easy dispersion and optimum storage stability at high temperature to the modified road binder.
