During the course of the 1990s, EPDM was the most widely used e lastomer (95%) in dynamic and semi-dynamic automotive insulation applications. However, around the beginning of 2000, the sector especially focused on a new material that offered pe rformances such as the EPDM, but that could be easily processed like thermoplastic material. Proflex TPV is a dynamic mix between EPDM and polypropylene. Proflex offers a combination of excellent thermoplastic and elastomeric properties, hardness, flexibility, elasticity. Thanks to its characteristics, TPV allows considerable savings during assembly of the finished pieces. TPV scrap is 100% recyclable and can be reworked. Thanks to Proflex TPV, the weight of the moulded pieces can be reduced by 20-30%, thus cutting down on costs. Expensive secondary operations related to the finish can be reduced or even eliminated. The versatility of the TPV encourages the design of new systems and the consolidation of parts, so that other thermoplastic materials can be easily integrated and metal inserts can be eliminated. At the end of the process, the costs of finished parts are usually 20% lower compared to those of EPDM.
