ABS (Acrylonitrile-Styrene-Butadiene Copolymer, ABS is the acronym of Acrylonitrile-Butadiene-Styrene) is a thermoplastic polymer material with high strength, good toughness and easy processing and molding. Because of its high strength, corrosion resistance and high temperature resistance, it is often used to manufacture the plastic shell of instruments.

Linear low density polyethylene (LLDPE) is considered as a new variety of "the third generation polyethylene". Compared with ordinary low density polyethylene, LLDPE has lower energy consumption and higher output. In particular, its physical and chemical properties are much better than ordinary low density polyethylene, and it is widely used.

Hips is an impact-resistant polystyrene product produced by adding polybutadiene rubber particles into polystyrene. This polystyrene product will add micron-sized rubber particles, and the polystyrene and rubber particles will be connected together by grafting. When impacted, the tip stress of crack propagation will be released by relatively soft rubber particles. Therefore, the crack propagation is hindered and the impact resistance is improved. Polystyrene is a kind of brittle plastic with wide applications. The computer case you are using now is made of polystyrene. Transparent plastic water cups and foamed plastics for packaging are also made of polystyrene. Polystyrene is a kind of polyolefin, which is formed by free radical polymerization of styrene. A new type of polystyrene, syndiotactic polystyrene, can be obtained by metallocene catalytic polymerization. The benzene rings of syndiotactic polystyrene are alternately connected to both sides of the main chain, while those of ordinary polystyrene are randomly connected to both sides of the main chain. Syndiotactic is a crystalline polymer with a melting point of 270℃. Polybutadiene was added to the styrene polymerization system to graft polymerize styrene on the main chain of polybutadiene. Polystyrene and polybutadiene are incompatible, so styrene and butadiene segments aggregate separately, resulting in phase separation. These polybutadiene phase regions can absorb impact energy, thus improving the impact strength of polystyrene.

Polystyrene (PS) is polymerized from styrene monomer (SM), which can be polymerized by various synthetic methods. At present, bulk polymerization and suspension polymerization are mainly used in industry. The English name of polystyrene is polystyrene, abbreviated as PS (hereinafter referred to as PS). PS is a thermoplastic amorphous resin, which is mainly divided into general polystyrene (GPPS), impact polystyrene (HIPS) and expanded polystyrene (EPS).

Polypropylene (PP) is a lightweight plastic with excellent electrical properties, which can be used as a high-frequency insulation material with high moisture resistance. Polypropylene is a crystalline polymer. When the melt is condensed, it shows a large shrinkage rate (1.0%- 1.5%) due to the large change of specific volume and high molecular orientation. In the molten state, the effect of reducing the viscosity of PP by increasing the temperature is not significant. Therefore, in the molding process, the injection pressure and shear rate should be mainly increased to improve the molding quality of products. 0.94 g/cm

Polycarbonate (pc) is colorless, transparent, heat-resistant, impact-resistant and flame-retardant, and has good mechanical properties at ordinary use temperature. Compared with polymethyl methacrylate, polycarbonate has good impact resistance, higher refractive index and good processability, and has UL94 V-0 flame retardant performance without additives. However, the price of polymethyl methacrylate is lower than that of polycarbonate, and large devices can be produced by bulk polymerization. With the continuous expansion of polycarbonate production scale, the price difference between polycarbonate and polymethyl methacrylate is narrowing.

Polycarbonate has poor wear resistance. Some equipment used for wearing polycarbonate needs special surface treatment.

Polycarbonate is a common material in daily life. Because it is colorless and transparent and has excellent impact resistance, it is commonly used in daily life, such as optical disc, eyepiece, water bottle, bullet-proof glass, goggles, bank bullet-proof glass, headlights and so on. Animal cages, pet cages.

Polyamide (pa) is a tough angular translucent or opalescent crystalline resin. As an engineering plastic, PA has a molecular weight of 1.5-30000. Polyamide has high mechanical strength, high softening point, heat resistance, low friction coefficient, wear resistance, self-lubrication, shock absorption and silencing, oil resistance, weak acid resistance, alkali resistance and general solvent resistance, good electrical insulation, self-extinguishing, non-toxic, tasteless, good weather resistance and poor dyeability. The disadvantage is high water absorption, which affects dimensional stability and electrical properties. Fiber reinforcement can reduce the water absorption of resin and make it work at high temperature and high humidity. Polyamide has a good affinity with glass fiber. It is often used to make combs, toothbrushes, clothes hooks, fan ribs, net bags, fruit packaging bags, etc. Non-toxic, but can not be exposed to acid and alkali for a long time.
