High temperature range of pc materials. PC is a linear carbonate polyester, an almost colorless glassy amorphous polymer with good optical properties. It has good impact resistance and thermal deformation resistance. Let's look at the high temperature range of pc materials.
High temperature range of pc material 1. How many degrees of high temperature can a PC withstand?
The high temperature range is controlled at 45 degrees-135 degrees. If it exceeds this temperature range, it will easily lead to aging and deterioration of PC materials, and even make its inherent properties disappear.
PC material is a kind of material containing carbonate groups, which can be divided into aliphatic, aromatic and other categories according to its structure.
What are the uses of pc materials?
1, glass assembly industry
The common use of pc material is to make door and window glass, and its strength is relatively high. For example, it is also common in public places such as banks, and it can also be used on the aircraft cabin cover. There are also many protective covers of lighting equipment using this PC material.
There is also bulletproof glass, which is also a key material. For example, the bulletproof glass window of a car is also made of PC. For example, the dial of gasoline pump and the frame are also made of PC resin.
2. Packaging field
PC film is also widely used, not only for medical packaging, but also for making optical discs and films, which is deeply loved by people.
3. Building materials industry
Pc materials have good light transmittance and impact resistance, good processability and good performance in the construction industry. It can be said that the technology of this kind of products is higher than that of traditional materials, and it also occupies a high proportion in the market.
4. Medical field
Pc material is also a medical grade material, and it is also good to be a syringe. This syringe can also get rid of the original disposable shortcomings. After use, it can also be disinfected by steam, radiation, etc. , can also be cleaned with cleaning agent, not yellowing, not degradation of materials. Besides making high-pressure syringes, it can also make better materials for surgical masks and other equipment.
High temperature range of pc material 2 pc material is polycarbonate material and a tough thermoplastic resin. It is colorless, transparent, heat-resistant, impact-resistant, flame-retardant, high refractive index and good processability. Pc can be divided into: anti-static pc, conductive pc, fiber reinforced fireproof pc, UV-resistant and weather-resistant pc, food-grade pc and chemical-resistant pc.
The three major application fields of pc materials are glass assembly industry, automobile industry and electronic appliance industry, followed by industrial machinery parts, compact discs, packaging, computers and other office equipment, medical care, films, leisure and protective articles.
PC can be used as door and window glass, and PC laminates are widely used as protective windows in banks, embassies, detention centers and public places, as well as aircraft cabin covers, lighting equipment, industrial safety baffles and bulletproof glass.
The PC board can be used as various signs, such as gasoline pump dial, automobile dashboard, warehouse and open-air commercial signs, point slip indicator, PC resin for automobile camera system, dashboard system and interior decoration system, front lampshade, reinforced front and rear fenders of automobiles, mirror frames, etc.
PC is an ideal material for optical disk storage media. PC bottles (containers) are transparent, light in weight, good in impact resistance, resistant to certain high temperature and corrosive solution washing, and can be used as recyclable bottles (containers). PC and PC alloys can be used as computer racks, housings, auxiliary machines and printer parts. The modified PC is resistant to high-energy radiation sterilization, cooking and baking disinfection, and can be used in blood sample collection instruments, blood oxygenators, surgical instruments, renal dialyzers and so on. PC can be used as helmet and helmet, protective mask, sunglasses and sports goggles.
Main advantages
1, high strength and elastic coefficient, high impact strength and wide temperature range;
2. High transparency and no dyeing;
3. Low molding shrinkage and good dimensional stability;
4. Good fatigue resistance;
5. Good weather resistance;
6. Excellent electrical characteristics.
High temperature range of pc material 3 PC is a linear carbonized polyester. Carbonate groups in the molecule are alternately arranged with other groups, which can be aromatic, aliphatic or both. Bisphenol A PC is the most important industrial product.
PC is an almost colorless glassy amorphous polymer with good optical properties. PC high molecular weight resin has high toughness, the notched impact strength of cantilever beam is 600~900J/m, and the thermal deformation temperature of unfilled brand is about130 C, which can be increased by glass fiber reinforcement.
The bending modulus of PC can reach more than 2400MPa, and the resin can be processed into large rigid products. When it is lower than100 C, the creep rate under load is very low. PC has poor hydrolysis resistance and cannot be used for products repeatedly subjected to high-pressure steam.
Polycarbonate has good impact resistance, thermal deformation resistance, weather resistance and high hardness, and is suitable for producing various parts of cars and light trucks, mainly focusing on lighting systems, dashboards, heating plates, defrosting devices and bumpers made of polycarbonate alloy.
The three major application fields of PC engineering plastics are glass assembly industry, automobile industry and electronic appliance industry, followed by industrial machinery parts, compact discs, packaging, computers and other office equipment, medical care, films, leisure and protective articles.
PC can be used as door and window glass, and PC laminates are widely used as protective windows in banks, embassies, detention centers and public places, as well as aircraft cabin covers, lighting equipment, industrial safety baffles and bulletproof glass.
Application scope of pc plastics
1, electronic appliances, polycarbonate is an excellent insulating material, which is generally used to manufacture insulating connectors, coil formers, tube seats, insulating sleeves, machine housings and parts, and battery housings of miner's lamps.
2. Mechanical equipment can be used to manufacture various gears, racks, worm wheels, worms, bearings, cams, bolts, levers, crankshafts and ratchets, and can also be used as housings, covers and frames of some mechanical equipment.
3. Medical instruments, medical cups, tubes, bottles and dental instruments, containers and surgical instruments can even be used as artificial organs such as artificial kidneys and artificial lungs.
4. In other aspects, it is used as hollow rib double siding, greenhouse glass, etc. In architecture, it is also used as textile bobbin, bearing bushing of textile machinery, etc. In daily use, it is used as bottles, tableware, toys, models, LED lamp cases, mobile phone cases, etc.
