Hepla® PTE series materials are a class of new green engineering plastics with excellent performance and high application value. Hepla® PTE material has excellent performance. Hepla® PTE has outstanding resistance to hydrolysis. It can keep the material from deformation in a wet or liquid environment for a long time, and its overall performance is not affected. Compared with PA66, Hepla® PTE is in sufficient tension It still has excellent impact strength and elongation under strength; Hepla® PTE also has outstanding properties such as high toughness, good tensile strength and flexural modulus, good chemical resistance, and excellent flame retardant properties.
