The amount of plastic consumed by the electrical and electronic industry accounts for the third largest consumption of plastics, just following the packaging and construction industries. This article mainly introduces the application of plastics in the electrical and electronic industries.

Engineering Plastics in Electronic and Electrical Industry

Electronic components

Electronic components are generally centered on connectors, coils, and induction components, including filters, oscillators, and keys. The integration of these components and the emergence of surface decoration technology (SMT) have greatly increased the added value of electronic products.

Connectors

The connectors can be made of various materials, such as PA, PBT, PET, etc., among which the cost of the connectors produced by PA is lower. With the diversification of parts, PBT materials can be used when the requirements for dimensional stability and heat resistance are higher, and PC materials can be used for connectors with special requirements. Of course, PPS and LCP reinforced plastics with better heat resistance are also ideal candidates.

Coil bobbin

The coil bobbin is made by welding the coil wire and the terminal. After the terminal insert is formed, there are special requirements for its insertion process, especially when the large coil is welded, and the heat capacity is large, so PA, PBT, PC can be selected. Among them, PA and reinforced PA have the characteristics of high strength, high toughness, certain insulating properties, easy to form thin-walled skeletons and high production efficiency. With the development of relays, the requirement of miniaturization is put forward. Therefore, PPS should be used for materials that require short-term work at 260 °C.

Resistor

As the load in the circuit, the resistor plays the role of reducing the power supply voltage and adjusting the working voltage. Plastics are mainly used in resistors to manufacture components such as resistor skeletons, housings and gaskets. The requirements for the plastic skeleton are high mechanical strength, excellent electrical insulation properties, good heat resistance and dimensional stability. The commonly used materials are polysulfone, PBT, and injection grade phenolic plastic powder.

Transformer

The transformer is an important electronic and electrical component, which plays the role of changing voltage, transmitting voltage, transmitting power and impedance matching. Plastics can be used as skeletons and terminal blocks in transformers.

In the field of electronic and electrical industry, the amount of electronic circuit components, printed circuits, connectors and instrumentation equipment shells is constantly increasing, and the application fields are also expanding. Many structural parts of electronic products are developing in the direction of short, light and thin, which puts forward higher requirements for plastics in terms of quantity and quality. The continuous emergence of new high-performance plastic varieties will surely play a greater role in the electrical and electronic industry.
