Low density polyethylene (LDPE), also known as high pressure polyethylene, is a kind of plastic material, it is suitable for thermoplastic molding processing of various forming processes, forming processing is good. LDPE is mainly used for thin film products, but also for injection products, medical devices, medicine and food packaging materials, blow molding hollow molding products and so on.

LDPE Granules
Low-density polyethylene (LDPE) is a synthetic resin using a high-pressure process via free radical polymerization of ethylene and is therefore also called high-pressure polyethyleneâ. It features light, flexible, good freezing resistance and impact resistance. LDPE is chemically stable. It has good resistance to acids (except strongly oxidizing acids), alkali, salt, and excellent electrical insulation properties. Its vapor penetration rate is low.
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. It is used in the production of food containers,stationery, packaging materials and houseware.
