Compared with other materials, plastic has the following performance characteristics:

1. Light weight

Plastics are lighter materials with a relative density between 0.90 and 2.2. Obviously, can plastic float to the surface? In particular, foamed plastics have a lighter texture and a lighter density with a relative density of only 0.01. This property allows plastics to be used in the production of products that require a reduction in their own weight.

2. Excellent chemical stability

Most plastics have good corrosion resistance to acids, alkalis and other chemicals. Especially known as the plastic king of PTFE (F4), its chemical stability is even better than gold, put in "Aqua regia" boiled for more than ten hours will not deteriorate. Due to its excellent chemical stability, F4 is an ideal corrosion resistant material. For example, F4 can be used as a material for conveying corrosive and viscous liquid pipes.

3. Excellent electrical insulation properties

Ordinary plastics are poor conductors of electricity, and their surface resistance and volume resistance are very large, which can be represented by numbers to 109 to 1018 ohms. The breakdown voltage is large and the dielectric loss tangent is small. Therefore, plastics have a wide range of applications in the electronics and machinery industries. Such as plastic insulated control cables.
