原材料PBT塑料GF 30%
PBT是乳白色半透明至不透明的结晶热塑性聚酯树脂。与PET-统称为热塑性聚酯，或饱和聚酯
高耐热性、韧性、耐疲劳性、自润滑性、低摩擦系数、耐候性、低吸水性，仅为0.1%，
在潮湿环境中仍保持各种物理性能（包括电性能）、电绝缘性，但体积电阻、介电损耗大。耐水、耐碱、耐酸、耐油，但易受卤化侵蚀，耐水解性差，低温结晶快，成型性好。缺点是缺口冲击强度低，成型收缩大。因此，当大多数填充有波浪纤维增强或无机材料时，其抗拉强度和拉伸深度可以提高一倍以上，并且热变形温度也会大大提高。在140℃下可长时间工作，波浪纤维增强后产品的纵向和横向收缩不一致，容易使产品翘曲
特点：
优良的机械性能、高机械强度、良好的抗疲劳性和尺寸稳定性，以及较小的蠕变。在高温条件下，这些特性很少发生变化

Raw Material PBT Plastic GF 30%
PBT is milky white translucent to opaque, crystalline thermoplastic polyester resin. With PET- collectively referred to as thermoplastic polyester, or saturated polyester.
High heat resistance, toughness, fatigue resistance, self-lubricating, low friction coefficient, weather resistance, low water absorption, only 0.1%,
In the humid environment still maintain a variety of physical properties (including electrical properties), electrical insulation, but volume resistance, dielectric loss is large. Heat resistant to water, alkali, acid and oil, but susceptible to halogenation erosion, poor hydrolysis resistance, rapid crystallization at low temperature, good formability. The disadvantage is that the notch impact strength is low and the molding shrinkage is large. Therefore, the tensile strength and tensile depth can be increased by more than one time and the thermal deformation temperature is also greatly increased when most of them are filled with wave-fiber reinforced or inorganic materials. It can work for a long time under 140-, the longitudinal and transverse shrinkage of the products after wave fiber reinforcement is not consistent, and it is easy to make the products warp.
Features:
Excellent mechanical properties, high mechanical strength, good fatigue resistance and dimensional stability, and small creep. These properties rarely change under high temperature conditions.
