Types of engineering plastics domestic common is polycarbonate, polyformaldehyde, polyamide, thermoplastic polyester, modified polyphenylene ether and so on the five major engineering plastics.
1>? Polyamide: (PA, common name: nylon) due to its unique low specific gravity, high tensile strength, wear resistance, self-lubricating, excellent impact toughness, with both rigid and flexible performance and win people's attention, coupled with its easy processing, high efficiency, light weight (only 1/7 of the metal), can be processed into a variety of products to replace the metal, is widely used in automotive and transportation industry. Typical products are pump impellers, fan blades, valve seats, bushings, bearings, a variety of instrument panels, automotive electrical instrumentation, hot and cold air conditioning valves and other parts, about each car consumption of nylon products amounted to 3.6 ~ 4 kg. Polyamide in the automotive industry, the largest proportion of consumption, followed by electrical and electronic.
2>? Polycarbonate: (PC) has a similar strength of non-ferrous metals, but also both ductility and toughness, its impact strength is extremely high, can not be destroyed by hammering, can withstand the explosion of the fluorescent screen of the TV set. Polycarbonate transparency and excellent, and can be applied to any coloring. Because of the above excellent performance of polycarbonate, has been widely used in a variety of security lampshade, signal lamps, gymnasiums, stadiums, transparent protective panels, lighting glass, high-rise building glass, automobile mirrors, windshield panels, aircraft cockpit glass, motorcycle driving helmets. The markets with the highest usage are computers, office equipment, automobiles, replacement glass and sheets, and CD and DVD disks are one of the most promising markets.
3>? Polyformaldehyde: Polyformaldehyde (pom) is an engineering plastic with excellent performance, in foreign countries have "capture steel", "? Pom has similar metal hardness, strength and steel, in a wide range of temperature and humidity have good self-lubrication, good fatigue resistance, and rich in elasticity, in addition it has good chemical resistance. pom to lower cost than many other engineering plastics, is replacing some of the market traditionally occupied by metal, such as zinc, Brass, aluminum and steel to make many parts, since its inception, pom has been widely used in electrical and electronic, machinery, instrumentation, daily light industry, automotive, building materials, agriculture and other fields. In many new areas of application, such as medical technology, sports equipment, etc., pom also showed good growth.
4>? Polybutylene terephthalate: (PBT) is a thermoplastic polyester, non-reinforced PBT and other thermoplastic engineering plastics, compared with the processing performance and electrical properties of the better. PBT glass transition temperature is low, the mold temperature of 50 ° C can be quickly crystallized, short processing cycle. Polybutylene terephthalate (PBT) is widely used in the electronic, electrical and automotive industries. Due to the high insulation and temperature resistance of PBT can be used as a television set back to the scanning transformer, car distributor and ignition coil, office equipment shell and base, a variety of automotive exterior parts, air conditioning fan, electronic stove base, office equipment shell parts.
5>? Polyphenylene ether: chemical formula referred to as PPO. 2,6-disubstituted phenol by oxidative coupling polymerization of thermoplastic resins, usually in the form of a yellow powder. Commonly used by the 2,6-dimethyl phenol synthesized polyphenylene ether, with excellent overall performance, the most important feature is in the long-term load, has excellent dimensional stability and outstanding electrical insulation, the use of a wide range of temperatures can be? The polyphenylene ether can be used for a long time in the range of -127～121℃. It has excellent water and steam resistance, high tensile and impact strength, and good creep resistance. In addition, there are good wear resistance and electrical properties. Mainly used instead of stainless steel to manufacture surgical medical equipment. In the electromechanical industry can make gears, blower blades, pipes, valves, screws and other fasteners and connectors, etc., but also for the production of electronic and electrical industry parts, such as coil skeleton and printed circuit boards.
Three? What are the engineering plastics
1, thermoplastic: resin for the structure of linear or branched macromolecular chain.
Polyethylene (PE), polypropylene (PP), polystyrene (PS), polyvinyl chloride (PVC), polyacetal (POM), polyamide (commonly known as nylon) (PA), polycarbonate (PC), acrylonitrile-butadiene-styrene*** polymer (ABS), polymethyl methacrylate (commonly known as plexiglass) (PMMA), acrylonitrile-styrene*** polymer (A/S), polyester (PETP polybutylene terephthalate, PBTP polyethylene terephthalate)
2, thermosetting plastics
Phenolic resins (PF), epoxy resins (EP), amino resins, alkyd resins, allyl resins, urea-formaldehyde resins (UF), melamine resins, unsaturated polyester (UP), silicone resins, polyurethane (PUR)
3, general-purpose plastics
Polyvinyl chloride, polystyrene, polyethylene, polypropylene, phenolic resins, amino resins
4, engineering plastics
Broad: Where the plastic can be used as an engineering material, that is, structural materials.
Specialized: with certain metal properties, can withstand certain external forces, and have good mechanical properties, electrical properties and dimensional stability, in high and low temperatures can still maintain its excellent performance of plastics.
General engineering plastics: polyamide, polycarbonate, polyformaldehyde, acrylonitrile-butadiene-styrene*** polymer, polyphenylene ether (PPO), polybutylene terephthalate (PBTP) and its modified products.
Specialty engineering plastics (high-performance engineering plastics): high-temperature resistant, structural materials. Polysulfone (PSU), polyimide (PI), polyphenylene sulfide (PPS), polyethersulfone (PES), polyarylate (PAR), polyamide imide (PAI), polyphenylene ester, polytetrafluoroethylene (PTFE), polyether ketones, ion-exchange resins, heat-resistant epoxy resins
5. Functional Plastics (Specialty Plastics)
Radiation-resistant, super-conducting, magnetically conductive and Light-sensitive plastics and other special features. Fluorine plastics, silicone plastics
6, crystalline plastics
Molecules are arranged and maintain their shape of the plastic. PE, PP, PA
7, non-crystalline plastics
Long-chain molecules around a ball (for thermoplastic plastics) or into a mesh (thermosetting plastics), and maintain their shape of the plastic. ps, pc, abs.
Engineering plastics is the upgrade of the general-purpose plastic base. Because the molecular structure is different, so the chemical resistance, friction resistance, electrical properties, there are a number of differences. And because of the different molding methods, so some methods are applicable to every kind of plastic, while some molding methods can only be applied to a certain kind of plastic or a few kinds of plastic.Tubapu online free of charge for everyone to provide "each home decoration offer, 1-4 local decoration company, 3 sets of decoration design scheme", and decoration to avoid pit strategy!
