Hytrel® HTR4275 BK316

Hytrel® HTR4275 BK316 by Celanese is a plasticizer-free thermoplastic polyester elastomer. It is light stabilized and contains a general-purpose stabilizer. It is pigmented black with fine particle size carbon black. It possesses good melt stability, excellent toughness, resilience, high resistance to creep, impact and flex fatigue. It shows flexibility at low temperatures, high melt viscosity and good retention of properties at elevated temperatures. It provides resistance to industrial chemicals, oils and solvents. It can be processed by blow molding, extrusion, thermoforming and injection molding method. Hytrel® HTR4275 BK316 is used in hollow thin wall parts requiring a tough polymer with excellent flexibility and temperature properties such as automotive boots.
