A Unique Combination of Flexibility, High Temperature Resistance and Strength

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).


Why Arnitel®

Why 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 can replace rubbers, metals, leather, and other thermoplastics. Arnitel® delivers superior chemical, heat, and wear resistance, along with the ability to be recycled.

Characteristics and Properties

We offer Arnitel® across a full portfolio of grades, each designed to meet specific customer needs. That includes grades suitable for injection molding, blow molding and extrusion – as well as Arnitel Eco, a bio-based thermoplastic copolyester (TPE). Characteristics and properties found across Arnitel® product lines include:

  • Elasticity - Arnitel® is a thermoplastic elastomer that combines the easy process of thermoplastics with the elasticity of a rubber. The soft Arnitel® materials show excellent elasticity and can be used as elastic fibers.
  • Thermal - Arnitel® is extensively used in applications over a very wide range of temperatures. Arnitel® retains its mechanical properties at very low temperatures of -113°F (-45°C) right up to 302°F (150°C).
  • Heat Aging - The Arnitel® C series shows outstanding high heat ageing properties and meets the most stringent performance and compliance needs, including hydrolysis and abrasion resistance. This series meets the severe ISO 6277 class D requirements for automotive wire and cable.
