TPC - Arnitel

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 also offers you exceptional flexibility in design. Giving you the freedom to implement your most innovative product concepts, and to add value to your design process. And as a result, helping you to meet your customers’ demands for ever-higher end-product performance and cost-effectiveness.Arnitel can also fulfill or even exceed the demands of applications that normally require conventional rubbers. And because it is available in a wide range of hardnesses, Arnitel has a unique capability to be used as a replacement for metals, leather, rubber and other thermoplastics. In many cases, delivering both superior performance and lower finished part costs.

Arnitel portfolio overview

Arnitel for cable insulation

With thermoplastic copolyetherester polymer as basis, Arnitel has a broad portfolio for cable insulation: cable insulation (jacket+primary insulation) for consumer products, for white goods and also for railway and automotive cable.

Next to insulation also a wide portfolio for strain reliefs and plugs is available.

Arnitel Eco

Our Arnitel® Eco material is a bio-based thermoplastic copolyester (TPE) that delivers high performance with the added benefit of a lower environmental impact. The material is 50% made from renewable resources, based on rapeseed oil instead of mineral oil. Yet…it performs outstandingly for demanding applications ranging from oven pan liners to consumer electronics to sports and leisure, automotive and furniture. Arnitel Eco materials can deliver up to a 40% reduction in carbon footprint compared to traditional co-polyesters.

Arnitel for automotive

Arnitel® is our family of Thermoplastic Copolyester Elastomers (known as TPE, COPE and TPC) ideal for many demanding automotive applications – from airducts to automotive tubes and hoses, to boots and bellows to automotive cables. In all cases this unique material gives you the strength and processing characteristics of engineering plastics combined with the performance of thermoset elastomers.

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.
