The introduction of the Thermoplastic polyester elastomer SUNPRENE^® TPEE： TPEE is a block copolymer who contains a hard segment of polyester and a soft segment of polyether; wherein the amorphous is formed from the soft segment of polyether and the uncrystallized polyester. Micro-crystals play a role as physical crosslinking points formed from the hard segment of the polyester. Thermoplastic polyester elastomer has the rubber elasticity and strength of engineering plastics. Soft segment gives it flexibility to make it like rubber; hard segment assigns the processing properties which makes it like plastic. Compared with rubber, it has a better processing performance and longer life; and the same high strength characteristics compared to plastic, while the flexibility and dynamic mechanical properties is better. TPEE has high strength, high flexibility, oil resistance, high temperature, radiation, dynamic mechanical properties superior to other properties;

    The guideline of High-performance grades of SUNPRENE^®TPEE molding processing:
TPEE exhibits hydrolyzing resistance, then it doesn’t react with water in the air. Because it has a little water absorption ability, we must need to dry them before we process (although the moisture content of TPEE is less than 0.1%, extrusion and molding process is not will have a defect.), for the workpieces perfect.

    In acid medium, TPEE will degrade at high temperatures. Therefore, TPEE and acid additives can’t be used simultaneously.
Before the molding process, TPEE must be dried under oven at 100~110 ℃ for 3~5h, and then processed immediately, not to let them cooled and in damp air, or to affect their performance.

    Processing technology：
1、Injection molding：barrel temperature should be higher than the melting point of products 5~15 ℃, injecting pressure at 60~80 MPa, mold temperature at 20~50 ℃, injecting in a low speed.
