介绍———————— 

      pps塑胶原料的特性
      用玻璃纤维增强后的热性能指标更高，它的最高连续使用温度达400度，pps的热稳定性优良，加热至500度时重量损失不明显，至700度时才会完全降解，它的力学性能随温度的升高下降很少，在232度经5000h的热老化后，其抗弯强度和抗拉强度还能保持50%以上。pps的抗拉强度、抗弯强度等性能在工程塑料中属中等水平，而伸长率和冲击强度却很低，因此在受力构件中使用pps通常加入添加剂，如玻纤、碳纤、填料等来增强其力学性能，pps通过这种改性后，主要力学性能，如抗拉性能、抗弯性能、压缩和冲击强度均有大幅度提高，伸长率却有下降，改性后的pps能在长期负荷和热负荷的作用下保持高的力学性能和尺寸稳定性，在低于175度时不溶于任何已知的有机溶剂，pps与一般有机溶剂接触时不会出现塑件开裂现象。
      pps由于分子链是由苯环和硫原子交替排列组成，本身具有阻燃作用，无须加入阻燃剂就可以达到UL-94-VO级水平。它的极限氧指数可达44%-53%，与pvc相近，是一种自熄性塑料，pps对紫外线、射线等也很稳定，在照射时不会表面发粘或分解的现象。
      pps的主要不足是韧性较差，冲击强度较低，熔体粘度不够稳定等。
