Plastic nets tell the advantages and disadvantages of PC materials

Advantages of PC materials:

PC material is an amorphous thermoplastic resin with excellent comprehensive properties. It has excellent electrical insulation, elongation, dimensional stability and chemical resistance, high strength, heat resistance and cold resistance. It also has self-extinguishing. Flame-retardant, non-toxic, colorable, etc., you can see the shadow of PC plastic in every corner of your life, the characteristics of large-scale industrial production and easy processing also make its price extremely low. Its strength can meet the needs of everything from cell phones to bulletproof glass.

Disadvantages of PC materials:

1. Insufficient hardness compared with metal, which makes it easier to scratch, but its strength and toughness are very good, whether it is heavy pressure or general beating, as long as you are not trying to smash it with stones, it is long enough.

2, not resistant to strong acid, not resistant to strong alkali, not resistant to ultraviolet light, weak acid, neutral oil

PC materials - application areas:

Wide-wavelength optical instruments, as a transparent plastic engineering plastic, PC is widely used in the world as a disc substrate, not only can prepare CD, VCD, DVD disc, but also can be applied to the substrate of high-density recording disc. In particular, the copolymer formed by grafting PC with styrene has an excellent application effect. The PC sheet is particularly suitable for the production of spectacle lenses, and the introduction of a siloxy group in the PC molecular chain can improve its hardness and scratch resistance. PC is used as a high refractive index plastic for the core material of high temperature resistant optical fiber. If the C-H chain in the PC molecular chain is replaced by a C-F chain, the absorption of visible light can be reduced, and the transmission can be effectively reduced. Loss of signal. In addition, the PC has good light transmission, and it is very popular and has potential in the construction of transparent window materials, high-rise building curtain walls, airports and stadiums. The focus in the future is to improve surface hardness and antistatic properties. Flame-retardant and environmentally-friendly communication appliances are widely used in the field of communication and telecommunication equipment due to the good electrical insulation properties of PC. At present, PC has replaced a large number of original phenolic plastics. In the future, it will focus on the development of flame-retardant PCs in the field of communication appliances, so there is no pollution resistance. The burning of PC materials has become the focus of development. Brominated flame retardants are reduced in toxicity, and halogen-free environmentally friendly phosphorus-based flame retardants can significantly reduce the heat distortion temperature and impact strength of PC. Therefore, silicone-based resists are more suitable.

With the lightweight and miniaturization of communication appliances, higher requirements are imposed on PC materials. At present, PC/ABS alloys are particularly suitable for applications in the communications and aerospace industries. Surface-metallized automotive parts, PC surface metallized with good metallic luster and high strength, widely used in a variety of automotive parts, but its impact toughness will be reduced during the plating process, so the use of elastomer and PC blending Modification, the elastomer is dispersed to cause cracking stress, although electroplating will not reduce its impact toughness, so the electroplating grade PC resin has great development prospects. In addition, the surface-metallized PC can also be used as a shielding material for electromagnetic waves in computers.

A food container with low residual harmful substances, the industrial synthetic PC material is a bisphenol type, and a small amount of unreacted monomer bisphenol A remains in the resin during synthesis, and is easily dissolved as a drinking water tank and a food container. It affects people's health. Therefore, it is necessary to develop sanitary PC resin for the production and use of drinking buckets and other food containers. The domestic application prospects are very promising.
