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.
