In modern industry, plastic has become an indispensable material. Among them, engineering plastics, as a kind of high-performance plastics, are favored because of their excellent characteristics such as high heat resistance, high strength and high rigidity. There are many kinds of engineering plastics, and all kinds of engineering plastics have different characteristics and application fields. Below, we will step by step in-depth understanding of engineering plastics is what material, as well as its characteristics, types, applications and other aspects of the content.

1. What is engineering plastics?

engineering plastics refers to one or more polymer materials after modification, adding the right amount of fillers, toughening agents, lubricants and other additives, processed by specific processing methods of high-performance plastics. In engineering plastics, there are usually many different chemical compositions and structures to meet different industrial needs.

2. the characteristics of engineering plastics

1. high strength and excellent physical and mechanical properties: engineering plastics strength, hardness, impact resistance, wear resistance and other physical and mechanical properties are more excellent than ordinary plastics.

2. stable chemical properties: engineering plastics usually have good acid and alkali resistance, solvent resistance and other chemical properties, can be stable in a variety of harsh environments.

3. Good processing performance: Because engineering plastics have good thermal stability and wear resistance, they can be processed in various complex processes, including injection molding, extrusion, blow molding and other processing technologies. The main types of

3.

1. Polyamide engineering plastics: PA6, PA66, PA11, PA12, etc.

2. Polycarbonate engineering plastics: PC (polycarbonate), PC/ABS(PC/ABS alloy), etc.

3. Phenolic engineering plastics: PF (phenolic resin), POM (polyoxymethylene), etc.

4. Thermoplastic Elastomer Engineering plastics: TPE (thermoplastic elastomer), TPO (thermoplastic elastomer), etc.

4. Application Field

engineering plastics are widely used in various industrial fields because of their excellent characteristics such as high strength and heat resistance. The following briefly introduces several common application areas:

1. Automobile and transportation: Engineering plastics are widely used in automobile manufacturing, including decoration, structural parts, power systems, body accessories, etc.

2. electrical and electronic: engineering plastics in electrical and electronic equipment is also widely used, including sockets, switches, wire and tube, connectors and so on.

3. Machinery manufacturing: The excellent performance of engineering plastics also makes it widely used in machinery manufacturing, especially in the manufacture of some parts, such as tires, mechanical transmission components, etc.

engineering plastics is an excellent plastic material, which is widely used in various fields. Through the understanding of its characteristics, types and application fields, we can better choose the engineering plastics suitable for our needs, so as to make better use of its excellent performance.
