The introduction of thermoplastic polyester elastomer SUNPRENE®TPEE Fire series:
The series have good fire resistance, toughness and high or low temperature performance. It also retains the material itself, the physical and chemical properties of stability, can meet a variety of fire prevention purposes, including: electronic components, cables, hoses, sheaths, etc.
The guideline of SUNPRENE®TPEE Fire series molding processing:
TPEE exhibits hydrolyzing resistance, then it doesn’t react with water in the air. Because they have a little water absorption, we must need to dry them before we process (although the moisture content of TPEE is less than 0.1%, extrusion and molding process will not 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 they 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 speed in low speed.
2,Extruded into linear workpieces:when extruded into wire and other workpieces, barrel temperature should be higher than the melting point of products 5~10 ℃, recommended aspect ratio of 24:1, screw speed in medium-low speed.
