GF 20%填充PBT聚合物
PBT是一种坚硬的工程热塑性材料，是一种半结晶材料，具有良好的化学稳定性、机械强度、电气绝缘性能和热稳定性。这些材料在各种环境条件下都非常稳定
PBT的吸湿性较弱。非增强PBT的抗拉强度为50 MPa，玻璃添加剂类型PBT的抗拉强度为170 MPa。过量的玻璃添加剂会导致材料变脆。PBT的结晶速度非常快，由于冷却不均匀会导致弯曲变形。对于玻璃添加剂类型的材料，工艺方向上的收缩可以减少，但工艺垂直方向上的收缩基本上与传统材料的收缩没有区别。通常，材料收缩率在1.5%到2.8%之间。含有30%玻璃添加剂的材料收缩率在0.3%到1.6%之间。熔点（225°C）和高温变形温度低于PET材料。维卡软化温度约为170°C。玻璃传输温度在22°C和43°C之间。由于PBT的高结晶速率，其粘度非常低，塑料零件加工的周期通常较短
典型应用范围
家用电器（食品加工刀片、真空吸尘器组件、电风扇、吹风机外壳、咖啡用具等）、电器组件（开关、电机外壳、保险丝盒、电脑键盘按钮）

Product Details
GF 20% Filled PBT Polymer
PBT is a tough engineering thermoplastic material that is a semi-crystalline material with very good chemical stability, mechanical strength, electrical insulation properties and thermal stability. These materials are very stable under a wide range of environmental conditions.
PBT has a weak hygroscopic property. The tensile strength of the non-reinforced PBT is 50 MPa, and the tensile strength of the PBT of the glass additive type is 170 MPa. Excessive glass additives will cause the material to become brittle. The crystallization of PBT is very rapid, which will cause bending deformation due to uneven cooling. For materials with a glass additive type, the shrinkage in the process direction can be reduced, but the shrinkage in the vertical direction to the process is essentially indistinguishable from that of the conventional material. Generally, the material shrinkage rate is between 1.5% and 2.8%. Materials containing 30% glass additives shrink between 0.3% and 1.6%. The melting point (225 ° C) and high temperature deformation temperature are lower than PET materials. The Vicat softening temperature is approximately 170 °C. The glass trasitio temperature is between 22 ° C and 43 ° C. Due to the high crystallization rate of PBT, its viscosity is very low, and the cycle time of plastic parts processing is generally low.
Typical application range
Household appliances (food processing blades, vacuum cleaner components, electric fans, hair dryer housings, coffee utensils, etc.), electrical components (switches, motor housings, fuse boxes, computer keyboard buttons)
