Plastic is a multi-functional material, with a variety of different characteristics and properties, plastic parts in the parts of the processing and manufacturing and application is very wide, the following are common plastic material characteristics and application areas:
Step 1 Light weight
Plastics are usually very light and belong to low-density materials, which makes it an ideal choice in many applications, especially those that need to reduce weight without affecting the normal use of the product, such as automotive, aerospace, lightweight plastics can greatly reduce the overall lifting weight, improve fuel efficiency and reduce costs; In packaging and furniture manufacturing, lightweight plastics can make more lightweight furniture, increasing the convenience of handling and storage.
Step 2: Plasticity
Plastics have excellent plasticity and can be heated and plastic deformed to create a variety of shapes, from simple flat plates to complex three-dimensional structures. This plasticity makes the plastic molding process very flexible and efficient.
3. Chemical stability
Many plastics have good resistance to a variety of chemicals, which makes it widely used in the chemical industry, medical equipment and laboratory supplies, chemical storage containers, food packaging, pipe fittings and other fields.
4. Insulation performance
Plastics are often excellent insulators and can be used in electrical and electronic applications to isolate current or protect electronic components from environmental factors. Such as chassis, panel, socket, insulation gasket, insulation sleeve, connector insulator.
5. Wear resistance
Some plastics have excellent wear resistance and can be used to make bearings, bearing sleeves, sliding seats, ball reholders, gears, rashes, seals, gaskets, blades, pump parts, valve seats and other parts that need to withstand friction and wear.
6. Transparency
Such as polycarbonate (PC) and polymethyl methacrylate (PMMA), with good transparency, can be used to manufacture transparent parts and Windows.
7. Impact resistance
Such as polypropylene (PP) and polyethylene (PE), which have good impact resistance, can be used to make durable packaging materials and containers.
8. Heat resistance
Certain high-performance plastics, such as polytetrafluoroethylene (PTFE) and polyether ether ketone (PEEK), have excellent high temperature resistance and are suitable for applications in high temperature environments.
9. Cost-effectiveness
Plastics typically have lower production costs, making them very competitive in high volume production.
It is important to note that different types of plastics have different characteristics, so the choice of materials must be considered according to the needs of the specific application. In addition, the use of some new composite materials and additives can change the properties of plastics to meet more special material needs. Therefore, in engineering and design, it is essential to know and understand the properties of plastic materials.
