ABS plastic is a terpolymer of three monomers, acrylonitrile (A), butadiene (B) and styrene (S). The relative content of the three monomers can be changed arbitrarily to make various resins.

ABS plastic has the common properties of three components, A makes it resistant to chemical corrosion, heat resistance, and has a certain surface hardness, B makes it have high elasticity and toughness, and S makes it have the processing and molding characteristics of thermoplastics and improve electrical properties. performance. Therefore, ABS plastic is a kind of “tough, hard and rigid” material with good comprehensive performance and wide application. ABS plastic has been widely used in machinery, electrical, textile, automobile, aircraft, ship and other manufacturing industries and chemicals

Polypropylene is a polymer obtained by addition polymerization of propylene. It is a white waxy material with a transparent and light appearance. The chemical formula is (C3H6)n, the density is 0.89～0.91g/cm3, it is flammable, the melting point is 189℃, it softens at about 155℃, and the operating temperature range is -30～140℃. It is resistant to corrosion by acid, alkali, salt solution and various organic solvents below 80 °C, and can be decomposed under high temperature and oxidation.

Polypropylene is widely used in the production of clothing, blankets and other fiber products, medical equipment, automobiles, bicycles, parts, transportation pipelines, chemical containers, etc., and also used in food and drug packaging.

Polycarbonate, also known as PC plastic; is a high molecular polymer containing carbonate groups in the molecular chain. According to the structure of ester groups, it can be divided into aliphatic, aromatic, aliphatic-aromatic and other types. Among them, the low mechanical properties of aliphatic and aliphatic-aromatic polycarbonates limit their application in engineering plastics. Only aromatic polycarbonates have been industrially produced. Due to the special structure of polycarbonate, it has become the fastest growing general engineering plastic among the five major engineering plastics.

Applications:

The three major application areas of PC engineering plastics are the glass assembly industry, the automotive industry and the electronics and electrical appliance industries, followed by industrial machinery parts, optical discs, packaging, computers and other office equipment, medical and health care, films, leisure and protective equipment, etc. PC can be used as door and window glass, and PC laminates are widely used in protective windows in banks, embassies, detention centers and public places, for aircraft canopies, lighting equipment, industrial safety baffles and bulletproof glass.

PC board can be used for various signs, such as gasoline pump dials, car dashboards, warehouse and open-air commercial signs, point slide indicators, PC resins are used in automotive lighting systems, dashboard systems and interior decoration systems, used as headlight covers, Reinforced car front and rear fenders, mirror frames, door frame covers, operating lever sheaths, spoilers, PC are used as junction boxes, sockets, plugs and bushings, gaskets, TV conversion devices, telephone line support under the communication Cable connectors, switch boxes, switchboards, switchboard components, relay enclosures. PC can be used as low-load parts for home appliance motors, vacuum cleaners, shampoo, coffee machines, toasters, handles for power tools, various gears, worm gears, bushings, guide gauges, and shelves in refrigerators. PC is an ideal material for optical disc storage media.

PC bottle (container) is transparent, light in weight, good in impact resistance, resistant to certain high temperature and corrosive solution washing, as a recyclable bottle (container). PC and PC alloys can be used as computer racks, shells and auxiliary machines, and printer parts. Modified PC is resistant to high-energy radiation sterilization, cooking and baking sterilization, and can be used for blood sampling equipment, blood oxygenators, surgical instruments, kidney dialyzers, etc. PC can be used as helmets and hard hats, protective masks, sunglasses and sports protection. Blindfolds. PC film is widely used in printing graphics, pharmaceutical packaging, film commutator.

The application and development of polycarbonate is developing in the direction of high compounding, high function, specialization and serialization. It has launched various grades for optical discs, automobiles, office equipment, boxes, packaging, medicine, lighting, films and other products. grade.
