Gehr PA12 TR® is a highly innovate low moisture absorbing transparent Polyamide. This polymer is used for applications with demanding requirements regarding resistance to chemicals and dynamic strength (high tensile strength with the added property of transparency).

Additionally, Gehr PA12 TR® has excellent UV resistance and tremendous climatic and atmospheric conditions endurance. Gehr PA12 TR® exhibits a surprisingly good stress crack resistance, although there is a lower stress failure level for amorphous materials. The material’s fatigue strength value is more than 30 MPa (10 million flexural fatigue cycles). Furthermore this product offers several benefits.
