Styroftax* - a Tailor-Made Experimental Styrene-Butadiene Copolymer with High flexibility and Resilience for Packaging Applications

摘要

Styroflex* is a new BASF experimental product based mainly on styrenc and butadiene. Our goal was to create a resin for food applications with similar or even improved characteristics compared to plasticized PVC. The new experimental product has to show the mechanics of a thermoplastic elastomer, e.g. low modulus and yield strength, high elongation and excellent recovery. It should be suited for high speed processing, especially for thin films. The latter aspect requires an intrinsic high thermal stability in order to avoid gel formation during processing.
