GPPS性能

GPPS是无色、无味、无味且有光泽的透明颗粒。质量轻、价格低、吸水率低、着色性好、尺寸稳定、电气性能好、产品透明、易于加工

GPPS可溶于芳香烃、氯代烃、脂肪酮和酯，但仅溶于丙酮。能承受某些矿物油、有机酸、碱、盐、低醇及其水溶液的作用。吸水率低，以在潮湿环境中保持其机械性能和尺寸稳定性。优异的电气性能，高体积和表面电阻，不受温度和湿度变化或电晕放电的影响。抗辐射性也很好

GPPS的主要缺点是易开裂、冲击强度低、耐热性差、不含沸水，只能在较低温度和低负荷下使用。耐日光性差，易燃。黑色时燃烧，有异味

Virgin Recycled GPPS Granules general purpose polystyrene GPPS resin

GPPS property

The GPPS are colorless, odorless, tasteless and shiny, transparent particles. Light quality, low price, low water absorption, good colorability, size stability, good electrical performance, transparent products, easy processing.

GPPS is soluble in aromatic hydrocarbons, chlorohydrocarbons, aliphaketone and esters but only in acetone. Can withstand the action of certain mineral oils, organic acids, alkali, salt, low alcohols and their aqueous solutions. The water absorption rate is low to maintain its mechanical properties and dimensional stability in a wet environment. Excellent electrical performance, high volume and surface resistance, and are not affected by temperature and humidity changes, or by corona discharge. Radiation resistance is also very good.

The main disadvantage of GPPS is brittle to crack, low impact strength, poor heat resistance, not boiling water, and can only be used at lower temperature and low load. Poor daylight resistance and flammable. Burning when black, and has a peculiar smell.
