PP contains no polar groups and has excellent electrical insulation properties. Its water absorption rate is less than 0.01%. PP is a semi-crystalline polymer with good chemical stability. Itis stable to most chemical except strong oxidizers. Inorganic acid, alkali and salt solutions have almost no damaging effect on PP. PP has good heat resistance and low density. Its melting point is at around 165â??. It has high tensile strength and surface hardness and good environmental stress crack resistance.It can withstand 120â?? continuously. Sinopec is the largest PP producer in China,Its PP capacity accounted for 45% of the country's total capacity. The company currently has 29 PP plants by the continuous process (including those under construction) PP Application PP has a variety of applications. It is suitable for multiple processing methods such as injection molding,extrusion molding and blow molding and is widely used in the textile,packaging, electrical household appliances, automobile and real estate industries. PP Injection Grade Application PP impact copolymer is widely used in the production of industrial products,such as dashboard, auto interior decorations, auto bumpers, interior and exterior parts of washing machine, accumulator containers and tanks. It can also be used to make household articles, such as bottle caps, cookware, furniture, toys, toolkits, travel cases, bags and various packaging containers. PP Application PP homopolymer is widely used in the production of small electrical household appliances, such as electric kettles, electric utensils, electric irons,air heaters,electric hair,dryers, electric toasters and electric hand dryers. PP random copolymer� Application PP random copolymer is widely used in the production of medical appliances with high transparence, such as medical syringes, medical infusion bottles,medical centrifuge tubes and sample tubes.
