AES & Troester : Coextrusion system for TPV and EPDM

Advanced Elastomer Systems, USA and Paul Troester Maschinenfabrik, Germany have jointly developed a co-extrusion process combining Santoprene thermoplastic vulcanisate and EPDM. Applications are seen in automotive and building profiles and weatherseals. The system consists of a 60 mm extruder for the Santoprene, a 90 mm vacuum machine for the EPDM and a specially developed die head. The system can process conventional solid profiles and can be combined with the water foaming process for Santoprene. The Santoprene can also be coloured.
