TPEE3362	Thermoplastic Polyester Elastomer TPEE	Secondary Coating Materials Used for Optical Fiber

Product description Thermoplastic polyester elastomer (TPEE) is a kind of block copolymer, It includes crystalline polyester hard segment which has properties of high melting point and high hardness and amorphous polyether or polyester soft segment which has properties of low glass transition temperature, It is formed into two phase structure, the hard segment crystallization have an effect on physical cross linking and stabilize product dimension, soft segment have an effect on amorphous polymer with high resilience.Therefore, To increase the proportion of hard section can improve the hardness, strength, heat resistance and oil resistance of TPEE. To increase the ratio of soft segments can improve the elasticity and low temperature deflection of TPEE.TPEE also has the properties of softness and elasticity of rubber, as well as the rigidity of thermoplastic and easy processing. Its shore’s hardness is 63D . Processing technology    The recommended processing temperature
