塑料球性能： 具有良好的抗化学药品性，低密度，密度小于水，吸水率低，熔点在热塑料中最高，具有良好的电绝缘体和低的电解质系数。经常用于有浮动能力要求的地方，用于输血器，液位校准指示器等。它具有很高的耐化学物质性，如酸、强碱、酒精；许多无机物质、盐溶液、汽油、水、石油、油脂、清洁剂、水果汁和牛奶等，但可以耐芳香族碳氢化合物和氯酸盐。 PP塑料球，聚丙烯塑胶球，Polypropylene塑料球有良好的耐溶剂、耐油类、耐弱酸、弱碱等性能，具有高度抗蠕变和应力能力，优良的耐磨性，自润滑性，耐疲劳性。PP塑料球的特性：比重小、无毒、绝缘、耐酸、耐碱、耐腐蚀。耐高温-25-+120°C. 应用：用于工艺品，装饰品，家用工具等 Plastic ball performance:Quality standards: No mold lines, without edges, smooth surface. With good chemical resistance, low density, low density, low water absorption, high melting point in the thermal plastic, with good electrical insulation and low electrolyte coefficient. Often used in a floating capacity requirements, for blood transfusion, liquid level calibration indicator, etc.. It has a very high resistance to chemical substances, such as acid, alkali, alcohol; many inorganic substances, salt solution, gas, water, oil, grease, cleaning agents, fruit juice and milk. But can be resistant to aromatic hydrocarbons and chlorate. PP plastic ball, polypropylene plastic ball, polypropylene plastic ball has good solvent, oil resistance, resistance to acid, alkali etc. properties, with high resistance to creep and stress ability, excellent wear resistance, self lubrication and fatigue resistance. The characteristics of PP plastic ball: the proportion of small, non-toxic, insulation, acid and alkali resistance, corrosion resistance. High temperature resistant -25~+120 C. Application: used in handicrafts, decorations, household tools, etc.
