Performance Advantages Of Heat-Resistant Engineering Plastics

General-purpose plastics have a long-term use temperature below 100°C. They usually include PE , PP , PS, PVC, ABS. Usually include PE, PP, PS, PVC, ABS. general-purpose plastics is a category of plastics that we use in large quantities in our daily life, usually used as packaging, daily necessities, toys and so on. The long-term use temperature of engineering plastics is around 100℃ to 150℃. The five major engineering plastics include PA, POM, PBT, PC and PPO, which are usually used in mechanical parts, automobiles, electrical and electronic appliances. High-temperature engineering plastics are used at temperatures above 150°C. In addition to high heat resistance and flame retardancy, these materials usually have good machinability, aging resistance, dimensional stability and excellent electrical properties. Can be used to replace metal materials, widely used in electronics and electrical appliances, aerospace, medical devices, automotive and other neighborhoods.

Engineering plastics performance advantages:

1. Light weight: the specific gravity of engineering plastics is routinely around 0.83~2.2, only 1/9~1/4 of steel and 1/2 of aluminum. Some engineering plastics, such as Polypropylene, are much lighter than water. This characteristic of engineering plastics is important for vehicles, ships, airplanes and other machinery and equipment that need to reduce self-weight.

2. Specific Strength: For equal volumes of material, engineering plastics are generally less strong than metals. However, when compared with equal weight, because engineering plastics are much lighter than metal, some engineering plastics have much higher strength than general metal, which is the higher strength of existing structural materials. For example, the modified reinforced PPS has good stiffness, and the product has the ringing sound of metal when it falls to the ground.

3. Good chemical stability: engineering plastics generally have good corrosion resistance to acids, alkalis and other chemicals, which is a very obvious advantage. Such as Polytetrafluoroethylene and Polyphenylene Sulfide have excellent corrosion resistance, which has a broad development prospect in the field of chemical anti-corrosion equipment and other fields.

4. Excellent electrical function: almost all engineering plastics have good electrical insulation function, dielectric loss is very small, good arc resistance, comparable with ceramic, rubber and other insulating materials. Therefore, the application of engineering plastics in the motor, electronic and electrical industry has an extremely broad prospect.

5. Friction reduction, good abrasion resistance: using this characteristic, engineering plastics can be used to manufacture a variety of self-lubricating bearings, gears and seals, etc.. Engineering plastics also has excellent foreign matter buried performance, used in the presence of abrasive particles or impurities in harsh conditions is particularly important.

6. Good vibration damping and muffling effect: machinery equipped with engineering plastics bearings and gears can reduce vibration, noise reduction and even muffling.

7. Easy molding and processing: engineering plastic products can often be molded at once, while metal products are always processed through several, dozens or even dozens of processes to complete. This feature of engineering plastics is important for saving working hours and improving labor productivity. In addition, engineering plastic products mechanical processing is relatively simple, stable size, low cost of molds, high yield.

Commonly high temperature engineering plastics are divided into the following categories: fluoroplastic (Fluoroplastie), polyaryl ether ketone (PAEK) class, high temperature nylon, polyphenylene sulfide (PPS), Polyimide ( PI ) class, polysulfone (PSU) class.

HONY PLASTIC for imported PI with non-standard parts have high performance chemical stability, mechanical toughness, natural lubrication, high temperature insulation. It can reduce the weight of parts, extend the maintenance interval or life, as well as increase process uptime to reduce overall costs, is an ideal design material. Applications include pump seats, seals and wear surfaces; structural and wear parts (for semiconductor and electronics manufacturing industries); fixtures and operating components for glass and plastics manufacturing; and more.
