Why is rubber material so important?
Rubber is a completely amorphous polymer, its glass transition temperature is low, the molecular weight is often very large, more than hundreds of thousands. Therefore, the properties of rubber materials are very good, which is one of the main reasons why people rely on it.Rubber can be divided into natural rubber and synthetic rubber according to the raw material. Natural rubber materials are made of latex, and part of the non - rubber contained in the latex is left in the natural rubber of the solid. Synthetic rubber is synthesized by high elasticity polymers, and is one of the three synthetic materials.
Rubber is a highly elastic polymeric material with reversible deformation. It is elastic at room temperature and can produce great deformation under very little external force. It can be restored to original state after removing external force. This is because the molecular chain of rubber can be cross-linked, and the crosslinked rubber has the ability to recover quickly when it is deformed by external force, and has good physical and mechanical properties and chemical stability. Rubber is the basic raw material of rubber industry. It is widely used in making tyres, rubber hoses, tapes, cables and other kinds of rubber products.
Human use of rubber is not a long time, from the beginning of modern times, the demand for rubber has been explosive growth. Rubber is a very important material in human daily life. It can be said that rubber is everywhere in our life. No rubber material, we cannot erase pencil handwriting, the faucet will become the fountain, car could not run up, no mouse pad, the mouse can't run without doing yoga yoga mat is very hard...... This shows that rubber is indispensable in our life.
Rubber can be divided into two types: general type and special type. The general rubber has good comprehensive properties and is widely used. Special rubber refers to some special properties of rubber, such as nitrile rubber has the characteristics of oil resistance, chloroprene rubber has anti-aging characteristics.Rubber material is a treasure. Rubber materials will continue to be the basic industry of economic development and will remain in existence long before human beings can develop new alternative materials.
