耐磨PPS BR-42B

耐磨PPS BR-42B---PPS plastic material EnglishName: phenylene sulfide specific gravity: 1.36 g / cm3 moldingshrinkage: 0.7% molding temperature: 300-330 ℃. It is a kind ofthermoplastic special engineering plastics with excellentcomprehensive properties. Its outstanding characteristics are hightemperature resistance, corrosion resistance and superiormechanical properties. PPS is a sulfur-containing aromatic polymer.Linear PPS is crosslinked above 350 ℃ to form thermosettingplastics. Branched PPS is thermoplastic

pps塑胶原料英文名称：Phenylenesulfide比重：1.36克/立方厘米成型收缩率：0.7%成型温度：300-330℃。它是一种综合性能优异的热塑性特种工程塑料，其突出的特点是耐高温，耐腐蚀和优越的机械性能。PPS是含硫芳香族聚合物，线型PPS在350℃以上交联后成热固性塑料，支链型结构PPS为热塑性塑料

PPS是工程塑科中耐热性zui好的品种之一，经玻璃纤维改性的料热变形温度一般大于260度,耐化学性仅次于聚四氟乙烯。它还具有成型收缩率小，吸水率低，防火性好．耐震动疲乏性好，耐电弧性强等优点，特别是在高温．高湿的环境下仍然有ji佳的电绝缘性。但其缺点是脆性大、韧性差，耐冲冲击强度低，经过改性后，可以克服上述缺点，获得十分优异的综合性能。

PPS is one of the best heat resistant varieties in engineeringplastics. The thermal deformation temperature of glass fibermodified materials is generally higher than 260 degrees, and thechemical resistance is second only to polytetrafluoroethylene. Inaddition, it also has the advantages of small molding shrinkage,low water absorption, good fire resistance, good vibration fatigueresistance, strong arc resistance, etc., especially in hightemperature and high humidity environment, it still has excellentelectrical insulation. However, it has the disadvantages of highbrittleness, poor toughness and low impact strength. Aftermodification, it can overcome the above shortcomings and obtainexcellent comprehensive properties.
