Arnitel® UM551-V

Flame Retardant (halogen- phosphorous-free)

General Information

Arnitel® is a high-performance ThermoPlastic Copolyester (TPC) that offers you a unique combination of flexibility, high temperature resistance and strength - plus excellent processing characteristics.
In industries ranging from automotive to E&E, Arnitel® is increasingly being as a lighter, smarter, greener alternative to conventional rubbers – reducing environmental impact and ultimately, system costs.
The product is supported by an experienced and knowledgeable global team continuously working on new ideas and applications, as well as exploring new markets. By listening to your needs and understanding your process and products, we develop solutions that make a real difference.
Product
  Due to limited hydrolysis resistance, this material should only be used in dry environments.
