PE is a polyethylene plastic with stable chemical properties. It is usually used to make food bags and various containers. It is resistant to acid, alkali and salt aqueous solutions, but it is not suitable to be wiped or soaked with strong alkaline detergents.
PP is polypropylene plastic, non-toxic and tasteless, and can be immersed in boiling water at 100°C without deformation or damage. Common acid and alkali organic solvents have almost no effect on it. Mostly used for food utensils.
PS is polystyrene plastic, easy to color, good transparency, mostly used to make lampshades, toothbrush handles, toys, electrical parts. It is resistant to acid and alkali corrosion, but is easily soluble in organic solvents such as chloroform, dichloroethylene, and banana water.
PVC is a polyvinyl chloride plastic with bright color, corrosion resistance, firmness and durability. Due to the addition of some toxic auxiliary materials such as plasticizers and anti-aging agents in the manufacturing process, its products generally do not store food and medicine.
ABS is a plastic polymerized by acrylonitrile, butadiene, and styrene. It has eye-catching color, heat-resistant, strong, and the outer surface can be plated with chrome, nickel and other metal films. It can be used to make piano keys, buttons, knife holders, TV shells, and umbrella handles. Wait.
PA is a nylon plastic. It is tough, firm, and wear-resistant. It is often used to make combs, toothbrushes, clothes hooks, fan bones, mesh bags, and fruit outer packaging bags. Non-toxic, but not long-term contact with acid and alkali.
Five general-purpose plastics: polyethylene, polypropylene, polystyrene, polyvinyl chloride, ABS (acrylonitrile-butadiene-styrene copolymer).
Common general plastic
Resin name, English abbreviation, main characteristics, main use
Polyvinyl chloride PVC has good chemical resistance, soft and hard products can be used for film, cable, floor, pipe
Polyethylene PE is light and soft, electrical insulation, chemical resistance film, bottles, electrical insulation materials, miscellaneous goods
Polypropylene PP is more transparent than PE, film with higher softening point, plastic rope, food utensils
Polystyrene PS is colorless and transparent, electrical insulation, good chemical resistance, electrical appliances, stationery, foam products, toys
AS resin AS is transparent, strong, oil resistant, electrical appliances, stationery, miscellaneous goods, toys
ABS resin ABS is tough, good gloss, chemical resistance, oil resistance, electrical appliances, auto parts, toys
Lunmeihuan) Polypropylene, code name: PP, is one of the lightest plastics. Its yield, tensile, compressive strength and hardness are better than low-pressure polyethylene. It has outstanding rigidity and resistance to stress relaxation at high temperatures (90°C). Good performance and good heat resistance. It can be used above 100℃. It will not deform at 150℃ without external force. It is stable in many media except concentrated sulfuric acid and concentrated nitric acid. Low molecular weight aliphatic hydrocarbons, aromatic hydrocarbons, and chlorine Hydrocarbon has softening and swelling effects on it, almost no water absorption, poor high-frequency electrical properties, easy molding, but large shrinkage, brittleness at low temperature, and low wear resistance. As a general structural part, as a material for corrosion-resistant chemical equipment and heated electrical insulation parts.
Polytetrafluoroethylene, code name: PTFE or F4. Generally called "non-stick coating" or "easy clean wok material"; it is a synthetic polymer material that uses fluorine to replace all hydrogen atoms in polyethylene. This material is resistant to acids, alkalis, and various organic solvents, and is almost insoluble in all solvents. At the same time, PTFE has the characteristics of high temperature resistance, and its friction coefficient is very low, so it can be used for lubrication, and it has become an ideal coating for easy-to-clean woks and water pipes.
Polyethylene, code name: PE. It has excellent dielectric properties, impact resistance, good water resistance, high chemical stability, operating temperature up to 80-100 ℃, good friction and cold resistance. The disadvantage is that the mechanical strength is not high, the quality is soft, and the molding shrinkage rate is large. It is used as the sheath of general cables, the structural parts of corrosion-resistant pipes, valves, and pumps. It can also be sprayed on the metal surface as a wear-resistant, anti-wear and anti-corrosion coating.
Polycarbonate, code name: PC. It has outstanding impact toughness and creep resistance, high heat resistance, and good cold resistance. The embrittlement temperature can reach -100°C. The flexural and tensile strength is equivalent to nylon, and it has a higher elongation and Modulus of elasticity, but fatigue strength is less than nylon 66, low water absorption, small shrinkage, good dimensional stability, abrasion resistance equivalent to nylon, and a certain degree of corrosion resistance. The disadvantage is that the molding conditions are more demanding. It can be used as various gears, worm gears, racks, cams, bearings, spindles, pulleys, transmission chains, nuts, washers, pump impellers, lampshades, containers, shells, covers, etc.
