What is the essential difference between plastic raw materials and engineering plastics?
engineering plasticIt's a kind of plastic, and a universal plastic.Like everyday things, what barrels, pots, plastic, etc?.Engineering plastics generally have many properties that are not common in plastics. They are often used in construction machinery to replace certain metals.Plastic is resin and filler, so it is usually granular. Raw materials too. Only a few powdery.

Engineering plastics are a type of plastics, as well as general plastics.Like everyday things, what barrels, pots, plastic, etc?.
Plastics can be divided into two major categories: General Plastics and engineering plastics. They are usually granular or powder in order to be easy to process before they are madeGeneral plastics refer to common plastics with large output, wide use, good formability and low price. Such as PVC, polyethylene, polypropylene, polystyrene and so on. Products made of plastic film, pipe, woven bags and plastic daily necessities. The yield and consumption of general-purpose plastics account for more than 80% of all plastics.Engineering plastics refer to plastics that meet the needs of industrial parts. Relatively speaking, they yield large, wide range of applications. Mainly ABS, polycarbonate, nylon, POM, modified polyphenylene ether, thermoplastic polyester and so on. Products have TV casing, plastic gears, optical materials, gaskets and so on.There is also a special engineering plastics, in addition to its characteristics of engineering plastics, its comprehensive performance is higher, long-term use temperature above 150 degrees celsius. It also has special functions and special uses. Mainly used in high-tech industries, such as atomic energy, rockets, satellites, aerospace, automotive, electronic and sports equipment, and other structural materials. Commonly used special engineering plastics are fluorine plastic, silicon resin, polyimide, peek, liquid crystal polymer and so on.
