产品：PBT聚对苯二甲酸丁二醇酯GF15
颜色：黑色/天然/白色
工艺：注射/挤出成型
PBT聚对苯二甲酸丁二醇酯GF15 V0
PBT聚对苯二甲酸丁酯GF15 V0是最坚硬的工程热塑性材料之一，是一种半结晶材料，具有优异的化学稳定性、机械强度、电气绝缘性能和热稳定性
非增强型聚对苯二甲酸丁二醇酯的拉伸强度为50MPa，玻璃用量PBT的拉伸强度为170MPa
过多的玻璃添加剂会导致材料变脆
聚对苯二甲酸丁二醇酯的结晶很快，由于冷却不均匀，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与普通材料基本相同。-一般材料收缩率在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%）和高温变形温度均低于PET材料
由于聚对苯二甲酸丁酯的结晶速率高，其粘度非常低，塑料零件加工周期通常较短 Product : PBT polybutyl terephthalate GF15 Color: Black/Natural/White ColorPBT Polybutyl Terephthalate GF15 V0

Product Details
PBT polybutyl terephthalate GF15 V0
PBT polybutyl terephthalate is one of the toughest engineering thermoplastic materials, it is a semi-crystalline material, has excellent chemical stability, mechanical strength, electrical insulation properties and thermal stability.
These materials have good stability over a wide range of environmental conditions.
PBT has weak hygroscopic properties.
The tensile strength of non-enhanced polybutyl terephthalate was 50 MPa, and that of PBT with glass dosage was 170 MPa.
Too many glass additives will cause the material to become brittle.
The crystallization of polybutyl terephthalate is rapid, which leads to bending deformation due to uneven cooling.
For materials with glass additive types, the shrinkage in the process direction can be reduced, but the shrinkage in the vertical direction of the process is basically the same as that of ordinary materials. – general material shrinkage between 1.5% and 2.8%.
The material containing 30% glass additive shrinks between 0.3% and 1.6%. Melting point (225%℃) and high temperature deformation temperature are lower than PET materials.
Vicat softening temperature is about 170℃. The glass transition temperature is between 22C and 43 C.
Because of the high crystallization rate of polybutyl terephthalate, its viscosity is very low, and the cycle time of plastic parts processing is generally low.
