TPC - Arnitel®

Arnitel is a thermoplastic elastomer (TPE) with high temperature resistance, good processability and excellent elastic behavior. Arnitel belongs to the TPE subcategory of thermoplastic copolyesters (TPC).

  • Broad range of hardnesses 
  • High temperature resistance within the TPE family
  • Mainly used to replace rubber in automotive, electronics and other industries.

Explore Arnitel®

Arnitel is increasingly being used as a lighter, smarter, greener alternative to conventional rubbers, reducing environmental impact and ultimately system costs. Thanks to its outstanding characteristics, Arnitel offers exceptional flexibility in design—giving the freedom to implement the most innovative product concepts, and to add value to the design process. Therefore, helping meet demands for ever-higher end-product performance and cost-effectiveness. Arnitel has a wide range of hardnesses, which is capable of replacing rubbers, metals, leather and other thermoplastics. Arnitel delivers superior chemical, heat and wear resistance, along with the ability to be recycled.

Arnitel is a thermoplastic elastomer that combines the easy process of thermoplastics with the elasticity of a rubber. The soft Arnitels show excellent elasticity and can be used as elastic fibers.


Arnitel is extensively used in applications over a very wide range of temperatures. Arnitel retains its mechanical properties at very low temperatures of -45°C right up to 150°C.

Reinventing the wheel with Arnitel®: Non-pneumatic tires that don’t go flat

The wheel has come a long way since its inception—evolved to the use of rubber tires inflated with air, which is the incumbent technology for decades.

However, in many applications and industries, dealing with flat tires is a pain and a costly nuisance. Learn how Arnitel— DSM’s family of thermoplastic elastomer polymers and compounds based on block copolymers of polyesters and polyethers— is helping manufacturers develop advanced non-pneumatic tires.
