PBT注射附件用PBT聚对苯二甲酸丁二醇酯颗粒
PBT注射附件用PBT聚对苯二甲酸丁二醇酯颗粒的产品细节PBT的工艺特性PBT的熔点为225~235°C，是一种结晶性材料，结晶度为40%
温度对pbt熔体粘度的影响不如剪切应力大。因此，在注射成型中，注射压力对pbt熔体的流动性有显著影响
在熔融状态下，pbt具有良好的流动性和低粘度，仅次于尼龙，在成型过程中容易“铸造”
pbt模塑制品的各向异性。pbt在高温下暴露于水时容易降解

Process characteristics of pbt
pbt has a clear melting point, with a melting point of 225 ~ 235 ° C. It is a crystalline material with a crystallinity of 40%.
The viscosity of pbt melt is not affected by temperature as much as the shear stress. Therefore, in injection molding, the injection pressure has a significant effect on the flowability of pbt melt.
In the molten state, pbt has good fluidity and low viscosity, second only to nylon, and is prone to “casting” during molding.
Anisotropy of pbt molded products. pbt is easily degraded when exposed to water at high temperatures.
