Product Texts
HiDura PTR 75HB NT0679 is a high-viscosity, heat-stabilized polyamide copolymer resin designed for extrusion applications. This product is available in natural only. It offers a well-balanced combination of engineering properties characterized by high melt point, high strength and flexibly, toughness and good chemical resistance. Specifically, its reduced crystallization, high melt point and heat stabilization make it a great solution for films being used in cooking or autoclave curing applications.
