The main component of the plastic raw material is a carbon-containing compound, which is composed of a polymer synthetic resin (polymer) as a main component, infiltrated with various auxiliary materials or additives, and has plasticity and fluidity at a specific temperature and pressure, and can be molded into A material that has a certain shape and that retains its shape under certain conditions.

Plastic has good insulation for electricity, heat and sound: electrical insulation, arc resistance, heat preservation, sound insulation, sound absorption, vibration absorption and excellent sound elimination performance.

Most of the plastic raw materials are extracted from some oils. The most familiar part of the PC material is extracted from petroleum. The PC material has a gasoline smell when it is burned; ABS is extracted from coal, and ABS is in When burned out, it will be soot; POM is extracted from natural gas, and POM will have a very smelly gas smell when it is burned.

With the rapid development of the plastics industry and the continuous improvement of plastic properties, plastic parts have been more widely used. Plastic parts are replacing traditional metal parts in different fields. A well-designed plastic part can often replace many traditional metal parts. In order to simplify the product structure and save manufacturing costs. Therefore, for the plastic precision requirements of plastic applications and market analysis, the recommended instruments for plastic testing are MUMA portable imager, VMS series optical image measuring instrument, VML series 3D optical image measuring instrument and so on.

Plastics are widely used and are indispensable parts in home appliances, automobiles, mobile phones, PCs, medical devices, and lighting appliances. As China's economy has achieved sustained and steady growth, industries such as home appliances, automobiles, mobile phones, PCs, and medical devices have benefited from a good external environment and have achieved rapid development. The development of downstream industries has further stimulated the demand for plastics.
