PBT有一个明显的熔点,熔点为225-235°C。它是一种结晶性材料,结晶度高达40%
PBT材料的耐高温性PBT熔体的粘度受温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熔体流动性的影响是明显的
PBT在熔融状态下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模塑制品是各向异性的。PBT在高温下暴露于水时容易降解

High Temperature Resistance Of PBT Material
Product Details
High temperature resistance of PBT material
Process characteristics of PBT:
PBT has an obvious melting point, with a melting point of 225-235°C. It is a crystalline material with a crystallinity of up to 40%.
High temperature resistance of PBT material
The viscosity of PBT melt is not affected by temperature as much as shear stress. Therefore, in injection molding, the influence of injection pressure on the fluidity of PBT melt is obvious.
PBT has good fluidity and low viscosity in the molten state, second only to nylon, and is prone to “casting” during molding.
PBT molded products are anisotropic. PBT is easily degraded when exposed to water at high temperature.
