So what specifically can Arnitel offer you in automotive PA12 replacement? It starts with a proven track record in automotive for many years, including applications like brake and airbrake tubes. In fact, Arnitel fulfills all standards for brake tubes (ISO7628, DIN 73378, DIN74324, FMVSS 49CFR571.106).

Arnitel delivers you great all-round mechanical performance with excellent burst-pressure and flex-behavior as well as very good fatigue, wear resistance and creep performance. This is coupled with outstanding long-term heat resistance (collapse temperature, peak temperature and continuous-use temperature). And crucially, for a polymer, Arnitel also offers excellent chemical resistance, against oils and grease.

This unique material provides ease of processing, enabling manufacturers to reduce weight, design products with thinner walls and more compact designs - by eliminating heat shields, for example. And it’s a sustainable solution: Arnitel is plasticizer and oil free, and is fully recyclable, helping reduce carbon footprint and potentially lower costs.
