Hytrel® TPC-ET 4068FG

Hytrel TPC-ET 4068FG is a low-modulus thermoplastic polyester elastomer (TPC-ET) with a nominal hardness of 31–37D. This FG grade is developed specifically for food-contact applications and manufactured according to GMP principles. It offers excellent toughness, resilience, flexibility at low temperatures and strong retention of mechanical properties at elevated temperatures. The material provides outstanding resistance to creep, impact and flex fatigue, and resists many industrial chemicals, oils and solvents. Hytrel TPC-ET 4068FG contains a non-discoloring stabilizer and can be processed using conventional thermoplastic techniques such as injection molding and extrusion.
