Plastic Applications in Electrical And Electronic
Electronic appliances are everywhere in our lives, and electricity brings us a more convenient life, but at the same time, have you discovered that when you find these electrical devices, you will also see plastics applied to them? Computers, or washing machines, vacuum cleaners, etc. in everyday life, you will see the applications of plastics, making these electronic devices lighter, safer and more durable.
Plastics can be divided into two categories: thermoplastic plastics, which can be repeatedly melted and formed; thermosetting plastics, once solidified, cannot be melted again, suitable for applications that encounter heat.
Why do we choose plastics for the electronics and telecommunications industries?
- Electrical insulation: Electricity brings convenience to our lives, but it can also be dangerous, so we use insulation properties in electronic devices for non-conductive properties. For example, PVC is used for insulated wires, and thermoset plastics can withstand high temperatures, and are used for switches, lamps, and handles of electrical equipment. Now we can see that most hair dryers, electric coffee machines, electric juice machines, electric razors, etc., have a plastic product shell design to protect users from the danger of leakage and conduction.
- Insulation: The thermal conductivity of plastics is poor. With this feature, manufacturers can add plastics to special flame retardant additives when they produce ovens, kettles, and fryer products to reduce heat and protect the user from the risk of burns.
- Lightweight: Plastics are lighter than other materials (metals, etc.), so they are designed to be used in a variety of electronic devices to reduce the weight of their products, allowing users to use them lighter and reduce the power lost due to weight.
- Freedom of design: Plastics can be designed in a variety of styles, such as color, transparency, light or smooth surface, etc. Designers can design a variety of patterns and meet the needs of product characteristics.
- Durable: Plastic is not only durable, waterproof, hygienic, easy to clean and maintain, and does not oxidize or corrode like metal. Plastic has oil and acid resistance.
- Energy saving: Plastics consume less fossil fuel than traditional materials, so the plastic manufacturing process is much cheaper.
- Recyclable: When the product needs to be eliminated because it is old, some plastic parts can be recycled.
The above are the characteristics of plastics used in electronic telecommunication products.
