PBT耐磨塑料颗粒
。在乙二醇变压器油（90）中浸泡5H，不会发生应力开裂，而PC和聚砚的开裂时间小于1H。PBT的耐老化性也相当。值得注意的是，在长期暴露于高温条件下，其各项力学性能变化不大，但在相同条件下POM 250小时后，其抗拉强度将急剧下降。PBT的耐热性和耐湿性较差，不耐高温和蒸汽。PBT长期浸泡在高温热水中，其大分子会被水解，导致分子量和性能下降。但在80以下的热水中，其性能不受影响。PBT可在60℃以下的热水中长期连续使用
加工性能
<1）PBT具有一定的吸水性，加工前需要干燥
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、电吹风外壳、咖啡器皿等）、电气组件（开关、电机外壳、保险丝盒、计算机键盘按钮等）、汽车工业（散热器格栅）、车身面板、轮罩、门窗零件、，等等）

PBT Wear-resistant Plastic Particles
Product Details
PBT wear-resistant plastic particles
PBT has low internal stress and excellent stress cracking resistance. When immersed in glycol transformer oil (90) for 5H, no stress cracking occurs, while PC and polyinkstone cracks less than 1H. The aging resistance of PBT is also equivalent. It is prominent that under long-term exposure to high temperature conditions, its various mechanical properties have little change, but after POM is 250H under the same conditions, the tensile strength will drop sharply. PBT has poor heat and humidity resistance, and is not resistant to heat and steam. PBT is immersed in high temperature hot water for a long time, its macromolecules will be hydrolyzed, resulting in a decrease in molecular weight and performance. But in hot water below 80, its performance is not affected. PBT can be used in hot water below 60 Long-term continuous use.
PBT wear-resistant plastic particles
Friction and abrasion
The friction coefficient of PBT is very small, similar to POM, and its abrasion is much smaller than that of PC and POM. The abrasion of PBT with glass fiber reinforced is increased.
Processing performance
1) PBT has certain water absorption and needs to be dried before processing.
2) PBT is a highly crystalline polymer with an obvious melting point, generally 225. Once the temperature exceeds the melting point, the material begins to melt and the viscosity drops rapidly. However, when the temperature exceeds 270, the material begins to decompose, so the processing temperature of PBT is.
3) The glass transition temperature of PBT is 30, crystallization is easy and the crystallization speed is fast, and the mold temperature is about 60 to fully crystallize.
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, etc.), automotive industry (radiator grilles) , Body panels, wheel covers, door and window parts, etc.).
