The basic properties of plastics, what is the material of plastics?

The reason why plastics are developing rapidly and are widely used is that compared with other materials, they have the following characteristics:

Easy to form and low cost. Compared with traditional materials, plastics are highly malleable, have good processing technology, and are easy to form.

It has a certain strength and light weight. Such as glass fiber reinforced plastics.

The tensile strength can reach 170 400MPa, which is widely used in automobile shells, ship hulls and even space shuttles.

And the density of plastic is much lower than that of natural materials, only half of that of aluminum.

Stable corrosion resistance. Plastics are resistant to acid and alkali corrosion, and most paints used to protect other materials are mainly made of plastic (resin).

Good transparency and strong colorability. Most of them are transparent or translucent, shiny, and polystyrene.

and acrylic materials as transparent as glass.

Strong insulation and high wear resistance. Almost all plastics have excellent electrical insulation, and their properties are comparable to those of ceramics, so the insulation layer (such as sockets, wires, etc.) and the electrical housing in electrical products are made of plastic.

Shock absorption, sound reduction, light transmission and heat preservation. Some plastics are flexible and elastic and can be mechanically energized when subjected to external mechanical shocks and vibrations.

Converted into electrical energy, it not only extends the overall life of the product, but also protects the product from accidental collisions during transportation.

The material is light, not easy to corrode, chemically stable, strong impact resistance, good insulation, low thermal conductivity, good formability, good colorability, and low cost.

The main material of plastic is resin. Resins are polymer compounds that have not been mixed with various additives.

The term resin was originally named after lipids secreted by animals and plants, such as rosin, shellac, etc.

Resin makes up about 40% 100% of the total weight of plastic. The basic properties of plastics are mainly determined by the nature of the resin, but additives also play an important role.

Some plastics are basically composed of synthetic resins with little or no additives, such as plexiglass, polystyrene, etc.

Plastic materialMaterial Properties:

1. Chemical resistance.

2. Luster, partially transparent or translucent.

3. Most of them are good insulators.

4. Light weight and sturdy.

5. It is easy to process and can be produced in large quantities, and it is cheap.

6. It has a wide range of uses, many effects, easy coloring, and some high temperature resistance.

The main properties are as follows:

Most plastics are lightweight, chemically stable, and have good impact resistance;

It has good transparency and abrasion resistance;

Good insulation, low thermal conductivity;

The general formability and colorability are good, and the processing cost is low;

Most plastics have poor heat resistance, high thermal expansion rate, and are easy to burn;

Poor dimensional stability and easy deformation;

Most plastics have poor low temperature resistance and become brittle at low temperatures;

Prone to aging; Some plastics are soluble in solvents.

Summary. The plastic tourism material is light, not easy to corrode, chemically stable, strong impact resistance, good insulation, low thermal conductivity, good formability, good colorability and other properties.

How slow? The plastic tourism material is light, not easy to corrode, chemically stable, strong impact resistance, good insulation, low thermal conductivity, good formability, good colorability and other properties.

Plastics have excellent chemical stability and resistance, and most plastics have good corrosion resistance to acids, alkalis and other chemicals. Plastics have excellent electrical insulating properties. Plastic is a poor conductor of heat, which has the function of silencing and shock absorption.

The hardness, tensile strength, flammability and impact strength of plastics. Because the specific gravity of plastic is small and the strength is large, it has a high specific strength.
