Arnitel® UM551-V

Chemical Family: Polyesters

Arnitel® UM551-V is a high-performance thermoplastic copolyester (TPC) known for its combination of flexibility, high temperature resistance, and strength, complemented by excellent processing characteristics. In industries such as automotive and E&E, Arnitel® UM551-V is becoming a more sustainable and efficient alternative to traditional rubbers, leading to reduced environmental impact and lower system costs. It's important to note that this material is flame retardant (halogen-phosphorus-free) and should be used in dry environments due to limited hydrolysis resistance. Arnitel® UM551-V can be processed using both extrusion and injection molding technologies, offering versatility for various applications.
