Arnitel® UM552

Chemical Family: Polyesters

Arnitel® UM552 is a high-performance thermoplastic copolyester (TPC) renowned for its exceptional blend of flexibility, high temperature resistance, and strength, complemented by excellent processing characteristics. In industries ranging from automotive to E&E, Arnitel® UM552 is gaining prominence as a more sustainable and efficient alternative to traditional rubbers, leading to reduced environmental impact and lower system costs. It's important to note that due to its limited hydrolysis resistance, this material is suitable for use only in dry environments. Arnitel® UM552 can be processed using both extrusion and injection molding technologies, offering versatility for various applications.
