产品详细信息
PP塑料均聚物
良好的加工性能PP是一种结晶聚合物，其颗粒在一定温度下不会熔化，不像PE或PVC，后者在加热过程中随温度升高而软化。一旦达到一定的温度，PP颗粒就会迅速熔化，它们都可以在几度内转变为熔融状态。PP的熔体粘度相对较低，因此成型过程具有良好的流动性，尤其是当熔体流动速率较高时，熔体粘度较小，适用于大型薄壁产品的注射成型，如洗衣机的内筒
PP离开模具后，如果在空气中缓慢冷却，将形成较大的晶粒，产品的透明度将较低。如果在水中快速冷却（薄膜通过以下水冷方法生成），PP的分子运动会迅速冻结，无法形成晶体。此时，胶片是完全透明的。PP的成型收缩率较大，达到2%以上，远远大于ABS塑料（0.5%）。PP的成型收缩率可随其他材料的类型和添加量而变化。在制造尺寸匹配的注塑产品时，需要仔细考虑这一点

PP Plastic Homopolymer
Product Details
PP plastic homopolymer
Good processing performance PP is a crystalline polymer, and its particles will not melt below a certain temperature, unlike PE or PVC, which soften as the temperature increases during heating. Once it reaches a certain temperature, the PP particles melt quickly, and they can all be transformed into a molten state within a few degrees. The melt viscosity of PP is relatively low, so the molding process has good fluidity, especially when the melt flow rate is high, the melt viscosity is smaller, and it is suitable for injection molding of large thin-walled products, such as the inner barrel of a washing machine.
After PP leaves the die, if it is slowly cooled in the air, larger crystal grains will be formed, and the transparency of the product will be low. If it is rapidly cooled in water (the film is produced by the water-cooling method as follows), the molecular motion of PP is rapidly frozen and crystals cannot be formed. At this time, the film is completely transparent. The molding shrinkage rate of PP is relatively large, reaching more than 2%, which is much greater than that of ABS plastic (0.5%). The molding shrinkage rate of PP can vary with the type and amount of other materials added. This needs to be carefully considered when making injection molded products with matching dimensions.
