Plastic product performance and characteristics

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

1. Lightweight

Plastics are lighter materials, relative density distribution between 0.90-2.2. Obviously, can plastic can't float on the water? In particular, foaming plastics, because there is micropores, lighter texture, relative density is only 0.01. This feature allows plastics to be used in the production of products that are relieved.

2. Excellent chemical stability

Most plastics have good corrosion resistance to acids, alkali-and other chemicals. In particular, it is commonly known as the polytetrafluoroethylene (F4) of the plastic king, and its chemical stability is even better than gold, and it will not become metastasis in "Wang Water". Since F4 has excellent chemical stability, it is an ideal corrosion resistant material. As F4 can be used as a material that delivers corrosive and viscous liquid pipes.

3. Excellent electrical insulation performance

Ordinary plastics are electrically poor conductors, their surface resistance, large volume resistance, with numbers to represent 109-1018 ohms. The breakdown voltage is large, the medium loss angle is small. Therefore, plastics have a wide range of applications in the electronics industry and machinery. Such as plastic insulated control cables.

4. Hot poor conductors, have no sound, shock absorption

In general, the thermal conductivity of plastic is relatively low, equivalent to steel 1 / 75-1 / 225, foamy micropores.

The gas contains gas, which is thermally insulated, soundproof, and shockproof. If the thermal conductivity of the polyvinyl chloride (PVC) is only 1/357 of the steel, 1/1250 of the aluminum. On insulation, single glass windows are 40% higher than single glass, and the double glass is 50%. After combining the plastic form with hollow glass, use in a residential, office building, ward, and hotel, winter saves heating, and the summer season is approximately air conditioning, the benefits are very obvious.

5. Mechanical strength distribution and higher specific strength

Some plastic hard as stones, steel, some soft as paper, leather; from the hardness, tensile strength, elongation and impact strength of the plastic, have a wide range of distribution, and have a large number of choices. Due to the small specific gravity of the plastic, the strength is large, and thus has a higher specific strength. Compared with other materials, plastics also have obvious disadvantages, such as flapping, stiffness is not as high, poor with poor aging resistance, and heat resistance.
