PVC material is a kind of plastic decorative material, which is the abbreviation of polyvinyl chloride material, PVC(Polyvinyl Chloride, referred to as PVC) resin is made of vinyl chloride monomer (Vinyl Chloride)Monomer, referred to as VCM) thermoplastic polymer. As the main raw material, adding an appropriate amount of anti-aging agent, modifier, etc., is a material made by mixing, calendering, vacuum forming and other processes. PVC is an amorphous polymer, containing microscopic crystallinity of 5%–10%.Crystal (melting point 175 degrees). The molecular weight, crystallinity, softening point and other physical properties of PVC vary with the depending on the reaction conditions (temperature). Based on PVC resin, with stabilizers, plasticizers, A variety of additives such as fillers, colorants and modifiers are mixed with plasticization and molding to form PVC trees.

PVC material has the characteristics of light weight, heat insulation, heat preservation, moisture resistance, flame retardant, easy construction and so on. There are many specifications, colors and patterns, which are very decorative and are widely used in production and life. Such as PVC water pipes, PVC plastic doors and windows, and plastic toys containing PVC. Because it poses a hazard to the human body, countries such as Europe, Japan and South Korea have imposed restrictions on products using PVC as raw materials. The outstanding advantages of general PVC resin plastic products are flame retardancy, abrasion resistance, chemical corrosion resistance,The gas and water vapor have low leakage and good performance. In addition, comprehensive mechanical properties, product transparency, electrical insulation, heat insulation, noise reduction, shock absorption are also good, it is a general-purpose material with the most superior cost performance. The disadvantage is that thermal stability and impact resistance are poor, and brittleness is easy to occur during use of both rigid and soft PVC. Generally, PVC contains bis(2-ethylhexyl) adipate (DEHA) plasticizer which is not allowed by the relevant national standards. DEHA is easily released at high temperature (over 100 degrees Celsius), which is harmful to health after contact with the human body. Because PVC is a hard plastic, to make it soft, a large amount of plasticizer must be added, and the plasticizer is easily released in a heated environment. If DEHA is used, it will interfere with human endocrine, causing breast cancer in women, birth defects in newborns, reduction of sperm counts in men, and even mental illness.

PS, also known as polystyrene, was born in 1930 and is a thermoplastic. Transparent when unpigmented. When the product is dropped or tapped, it has a metal-like crisp sound, good luster and transparency, similar to glass, brittle and easy to break, and the surface of the product can be scratched with fingernails. Modified polystyrene is opaque. Common products: stationery, cups, food containers, home appliance shells, electrical accessories, etc.

PC is the abbreviation of polycarbonate, the English of polycarbonate is Polycarbonate, referred to as PC engineering plastics.PC material is actually one of the so-called engineering plastics. As a material widely used in the world, PC has its own characteristics, advantages and disadvantages. PC is an amorphous thermoplastic resin with excellent comprehensive properties. Excellent electrical insulation, elongation, dimensional stability and chemical resistance, high strength, heat resistance and cold resistance; also has the advantages of self-extinguishing, flame retardant, non-toxic, colorable, etc., in your life The shadow of PC plastic can be seen in every corner, and the characteristics of large-scale industrial production and easy processing also make it extremely cheap. Its strength can meet various needs from mobile phones to bulletproof glass. The disadvantage is that its hardness is insufficient compared with metal, which makes its appearance easier to scratch, but its strength and toughness are very good, whether it is heavy pressure or general beating , as long as you don’t try to stone it, it’s long enough. Broad-wave light-transmitting optical equipment, as a kind of engineering plastic with good transparency, PC is widely used as a base material for optical discs around the world. In particular, the copolymer obtained by grafting PC and styrene has excellent application effect. PC sheets are especially suitable for making spectacle lenses. The introduction of siloxy groups into the PC molecular chain can improve its hardness and scratch resistance. As a high refractive index plastic, PC is used to make the core material of high temperature resistant optical fibers. 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, which can effectively reduce the transmission process. signal loss. In addition, PC has good light transmittance, which is very common and has potential in the application of transparent window materials for high-rise building curtain walls, airports and stadiums and other transparent building materials. In the future, the focus will be on improving surface hardness and antistatic properties. Flame retardant and environmentally friendly communication appliances, due to the good electrical insulation properties of PC, are widely used in the field of communication and telecommunication equipment.

At present, PC has replaced a large number of original phenolic plastics. Combustible PC materials have become the focus of development. Bromine-based flame retardants are being used less because of their toxicity, while halogen-free environmentally friendly phosphorus-based flame retardants will significantly reduce the thermal deformation temperature and impact strength of PC. Therefore, silicone-based flame retardants are more suitable. In addition, with the light weight and miniaturization of communication appliances, higher requirements are placed on PC materials. At present, PC/ABS alloys are particularly suitable for application in communication appliances and aerospace industries. Surface metallized auto parts, PC surface metallized has good metallic luster and high strength, widely used in various auto parts, but its impact toughness will be reduced during the electroplating process, so elastomer and PC are used to blend Modified, the combined elastomer disperses the cracking stress, and the impact toughness will not be reduced even after electroplating, so the electroplating grade PC resin is very promising. In addition, the surface metallized PC can also be used as a shielding material for electromagnetic waves and is used in computers. Food containers with low residual harmful substances, industrially synthesized PC is the bisphenol type. Since a small amount of unreacted monomer bisphenol A remains in the resin during synthesis, it is easily dissolved and affected when used as drinking water buckets and food containers. People are healthy, so it is necessary to develop hygienic PC resin for the production and use of drinking buckets and other food containers. The domestic application prospect is very promising. Anti-cracking and embrittlement medical devices, PC has many excellent properties. It has been used in medical devices. Due to its poor chemical resistance, it is easy to cause internal stress cracking in the presence of chemicals. For example, PC is used in artificial dialyzers, artificial The application of medical equipment such as lungs should solve the aging phenomenon of cracks caused by high temperature disinfection. If these shortcomings are overcome, the application of PC in medical equipment can be rapidly expanded.
