Arnitel® portfolio highlights

Arnitel® for cable insulation

With thermoplastic copolyetherester polymer as the basis, Arnitel has a broad portfolio for cable insulation for consumer electronics (jacket+primary insulation), appliances, railway and automotive cable products. Next to insulation, Arnitel also offers a wide portfolio for strain reliefs and plugs.

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 made from 50% renewable resources, based on rapeseed oil instead of mineral oil.

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, tubes and hoses to boots, bellows and cables. In all cases, this unique material gives you the strength and processing characteristics of engineering plastics combined with the performance of thermoset elastomers.

Elasticity

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.

Thermal

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.

Heat ageing

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.
