pps的介绍

它具有硬脆、结晶度高、阻燃、热稳定性好、机械强度高、电性能优异、耐化学性强等优点。聚苯硫醚是工程塑料中的耐热品种之一。玻璃纤维改性材料的热变形温度一般大于260℃，耐化学性仅次于聚-4。此外，它还具有低成型收缩率、低吸水率和良好的耐火性。良好的抗振动、抗疲劳、耐电弧等性能，尤其是在高温下。在高湿度下仍有电绝缘。但其缺点是脆性高、韧性差、抗冲击性差。经过改造，可以克服上述缺点，获得非常优异的综合性能

Introduction Of Pps

Product Details

Introduction of pps

It has the advantages of hard and brittle, high crystallinity, flame retardant, good thermal stability, high mechanical strength, excellent electrical properties, and strong chemical resistance. PPS is one of the heat-resistant varieties in engineering plastics. The heat distortion temperature of glass fiber modified materials is generally greater than 260 degrees, and the chemical resistance is second only to Poly-4. In addition, it also has low molding shrinkage, low water absorption and good fire resistance. Good vibration and fatigue resistance, strong arc resistance, etc., especially at high temperatures. There is still electric insulation under high humidity. However, its shortcomings are high brittleness, poor toughness, and low impact resistance. After modification, it can overcome the above shortcomings and obtain very excellent comprehensive performance.
