DSM Engineering Plastics has unveiled Arnitel thermoplastic copolymer-based elastomer (TPC) for use in wide range of automotive and industrial tubes and hoses from brake tubing and pneumatic tubing to hydraulic hoses. The unique material possesses the strength and processability of thermoplastics with the flexibility of a thermoset rubber - without the need for vulcanization. Arnitel TPC grades enhance design freedom and is proven to deliver system-cost efficiency due to weight reduction , integration of functions and reduction of overall process cycle time. Further, it is an environmentally responsible alternative (due to their recyclability) to traditional cross-linked rubber and polyamides which require plasticizers such as potentially harmful phthalates.
In the automotive sector, Arnitel TPCs offers improved heat resistance (up to 200°C) compared to polyamides (PA11 and PA12), good resistance to chemicals and oils, and superior fitting retention and are industry standards compliant. Typical automotive applications include vacuum brake tubing, air brake tubing, fuel tubing and convoluted tubing. As far as industrial applications are concerned, Arnitel are perfectly suited for hydraulic hoses with a smoother inner surface, high flexibility and better hot oil resistance relative to nitrile rubbers. These TPCs can also be used for pneumatic tubing.
