Product Description

Applied development industry

The three main application fields of PC engineering plastics are glass assembly industry, automobile industry, electronics and electrical appliances industry, followed by office equipment such as industrial machinery parts, compact discs, packaging, computers, medical and health care, film, leisure and protective equipment, etc. PC can be used as windows and doors, and PC laminates are widely used in protective windows of banks, embassies, detention centers and public places, as well as in aircraft hatches, lighting equipment, industrial safety baffles and bullet-proof glass.

PC board can be used as various signs, such as gasoline pump dial, automobile dashboard, warehouse and open-air commercial sign, point sliding indicator, PC resin for automobile lighting system, dashboard system and interior decoration system, as headlamp shade, front and rear baffles with reinforcing ribs, reflective mirror frame, door frame cover, operating rod sheath, baffle, etc. PC is used as junction box, socket, plug and sleeve, gasket, TV conversion device, connector of communication cable under telephone line bracket, switch box, telephone switchboard component, relay shell, PC can be used as low-load parts for household electrical appliances motor, vacuum cleaner, shampoo washer, coffee machine, baking surface. The handle of the Charter aircraft, power tools, all kinds of gears, worm gears, bushings, guides, and shelves in the refrigerator. PC is an ideal material for optical disc storage media.

PC bottles (containers) are transparent, light weight, good impact resistance, and can be washed with high temperature and corrosive solution. They can be used as recyclable bottles (containers). PC and PC alloys can be used as computer frames, enclosures and auxiliaries, and printer parts. Modified PC is resistant to high-energy radiation sterilization, cooking and baking disinfection. It can be used for blood sampling instruments, blood oxygenator, surgical instruments, kidney dialyzer, etc. PC can be used as helmet and safety helmet, protective mask, sunglasses and sports eye shield. PC films are widely used in printing charts, medical packaging and membrane commutators.

The application and development of polycarbonate is to develop in the direction of high compounding, high function, specialization and serialization. Various products, such as CD-ROM, automobile, office equipment, box, packaging, medicine, lighting, film and so on, have been introduced.

Building materials industry

Polycarbonate sheet has good light transmittance, impact resistance, dimensional stability of ultraviolet radiation resistance and its products, and good processing properties, which make it have obvious technical advantages over inorganic glass used traditionally in construction industry. China has built more than 20 production lines of polycarbonate building materials hollow panels, with an annual demand of about 70,000 tons of polycarbonate, reaching 140,000 tons by 2005.

Automobile manufacturing industry

Polycarbonate has good impact resistance, thermal distortion resistance, good weather resistance and high hardness, so it is suitable for producing various parts of cars and light trucks. It mainly concentrates on lighting system, dashboard, heating board, defroster and bumper made of polycarbonate alloy.

According to the data of developed countries, the proportion of polycarbonate used in the electronics, electrical and automobile manufacturing industry is 40%-50%, and that of China is only about 10%. The electronics, electrical and automobile manufacturing industry is the pillar industry of China's rapid development, and the demand for polycarbonate in these fields will be huge in the future. China has a large number of automobiles and a large demand, so the application of polycarbonate in this field has great potential.

specifications︰ Polycarbonate (PC) is a kind of carbonated polyester. Carbonate itself is not stable, but its derivatives (such as phosgene, urea, carbonate, carbonate) have certain stability.

According to the different structure of alcohol, polycarbonate can be divided into two groups: aliphatic and aromatic.

Aliphatic polycarbonate. For example, polyethylene carbonate, polytrimethylene carbonate and their copolymers can not be used as structural materials because of their low melting point and glass transition temperature and poor strength. However, their biocompatibility and biodegradability can be used in drug delivery carriers, surgical sutures and bone support materials.

Polycarbonate is resistant to weak acid, weak alkali and neutral oil.

Polycarbonate is resistant to UV light and alkali resistance.

PC is a linear carbonated polyester. Carbonate groups in the molecule are arranged alternately with other groups. These groups can be aromatic, aliphatic or both. Bisphenol A type PC is the most important industrial product.

PC is an almost colorless amorphous glass polymer with good optical properties. PC high molecular weight resin has high toughness. The notched impact strength of the cantilever beam is 600-900J/m, and the thermal deformation temperature of the unfilled grade is about 130 C. Glass fiber reinforced can increase this value by 10 C. The bending modulus of PC can be more than 2400MPa, and the resin can be manufactured into large rigid products. Under 100 degrees C, the creep rate is very low under load. PC has poor hydrolysis resistance and can not be used for products that are subjected to repeated high pressure steam.

The main performance defects of PC are low hydrolysis stability, sensitivity to notch, resistance to organic chemicals, poor scratch resistance and yellowing after long-term exposure to ultraviolet light. Like other resins, PC is susceptible to erosion by some organic solvents.

PC materials are flame retardant and wear resistant. Antioxidant activity.
