Simple classification of conductive plastics and main uses
Plastics are generally considered to be insulators and are often used as insulating materials. However, its high insulation brings some problems to processing and application. With the development of the electronics industry, technologies such as static elimination, electromagnetic shielding, and electrical conduction have received increasing attention. At the same time, conductive plastics have the characteristics of light weight, high strength, corrosion resistance, low cost and easy processing. They have very broad and optimistic application prospects in the electronics industry and other aspects.
What is conductive plastic?
The conductive plastic is a functional polymer material in which a resin and a conductive material are mixed and processed by a plastic processing method. Mainly used in electronics, integrated circuit packaging, electromagnetic shielding, and other fields.
The composite type is a composite of a conductive material and a polymer material. This category is slightly lower in cost and can meet various molding requirements. It is a type of functional polymer material that has been widely used.
Conductive plastic classification
1) According to the electrical properties, it can be divided into: insulator, anti-static body, electrical conductor, high conductor. Generally, a resistance value of 1010 Ω·cm or more is called an insulator; a resistance value of 104 to 109 Ω·cm is called a semiconductor or an antistatic body; and a resistance value of 104 Ω·cm or less is called an electric conductor; and the resistance value is 100 Ω? Below cm or even lower is called a high conductor.
2) According to the manufacturing method of conductive plastics, it can be divided into structural conductive plastics and composite conductive plastics.
3) According to the purpose, it can be divided into: antistatic materials, conductive materials and electromagnetic shielding materials.
Main use of conductive plastics
1) Anti-static turnover boxes, IC and LCD trays, IC packages, wafer carriers, film bags, etc. used in the production of precision electronic components such as integrated circuits, wafers, and sensor sheaths in the fields of electronics and electrical appliances.
2) The outer casing and structural parts of explosion-proof products, such as the outer casing and structural parts of electrical products used in coal mines, oil tankers, oil fields, dust and combustible gases.
3) Semi-conductive shielding materials used in medium and high voltage cables.
4) EMI shielding enclosures for electrical products in the fields of telecommunications, computers, automation systems, industrial electronics, consumer electronics, automotive electronics, etc.
5) Conductive plastics have more applications in other areas. For example, using its sensitivity to electrical signals can be used to make sensors. Because it can absorb microwaves, it can be used to evade radar by modulating into aircraft coatings. The effect; in rockets, ships, oil pipelines and sewage pipelines, it can also play its anti-corrosion function.
