Advantages And Disadvantages of Plastic Properties（1)

The advantages of plastics

1.Easy to process and manufacture (easy to shape)

Even if the geometric shape of the product is quite complex, as long as it can be demolded from the mold, it is relatively easy to produce. Therefore, its efficiency is far superior to metal processing, especially injection molded products. After a single process, very complex finished products can be produced

2.Can be colored as needed or made into transparent products

The use of plastic can produce colorful, transparent and beautiful products, and its ability to color freely can increase its commercial value and give people a lively feeling

3.Can be made into lightweight and high-strength products

Compared with metal and ceramic products, it is lightweight, has good mechanical properties, and has a higher specific strength (the ratio of strength to density), so it can be made into lightweight high-strength products. Especially after filling with glass fiber, its strength can be improved

In addition, due to the lightweight of plastics, which can save energy, their products are becoming increasingly lightweight

4.Not rusty or prone to corrosion

Plastics are generally resistant to the corrosion of various chemicals and are not as prone to rust or corrosion as metals. When in use, there is no need to worry about the erosion of acids, alkalis, salts, oils, drugs, dampness, and mold

5.Difficult to heat transfer and good insulation performance

Due to its high specific heat, low thermal conductivity, and difficulty in heat transfer, plastic has good insulation and thermal insulation effects

6.Can produce both conductive components and insulating products

Plastic itself is a good insulating material, and currently there is no electrical product that does not use plastic. However, if metal powder or debris is filled in plastic to form it, it can also be made into a product with good conductivity

7.Excellent shock absorption and noise reduction performance, with good light transmittance

Plastics have excellent shock absorption and noise reduction properties; Transparent plastics (such as PMMA, PS, PC, etc.) can be used to make transparent plastic products (such as lenses, labels, cover plates, etc.)

8.Low manufacturing cost of products

Although plastic raw materials themselves are not so cheap, they can reduce product costs due to their ease of processing and relatively low equipment costs
