Rubber wholesalers rubber raw materials are rubber or plastic, sulfur, vegetable oil and gravel.
Rubber: Highly elastic polymer material with reversible deformation. It is elastic at room temperature and can produce large deformation under the action of small external force. After the external force is removed, it can return to its original state and is not conductive. Rubber is a completely amorphous polymer. The glass transition temperature (TG) is low, and the molecular weight is usually large, exceeding hundreds of thousands.
The word rubber comes from an Indian cau-uchu meaning "tearful tree". Natural rubber is solidified and dried by the latex flowing out of the clover rubber tree during the rubber cutting process. In 1770, the English chemist J.Priestley discovered that rubber can be used to erase the handwriting of pencils. At that time, the material used for this purpose was called rubber, which is used today. The molecular chains of the rubber may be crosslinked. When cross-linked rubber is deformed under external force, it has rapid recovery ability, good physical and mechanical properties and chemical stability. Rubber is the basic raw material of rubber industry. Widely used in the manufacture of tires, rubber hoses, tapes, cables and other rubber products.
Rubber wholesalers rubber by raw materials into natural rubber and synthetic rubber. Can be divided into block raw rubber, latex, liquid glue and powder glue. Latex is a colloidal aqueous dispersion of rubber; liquid rubber is an oligomer of rubber, usually a viscous liquid before vulcanization; rubber powder is the processing of latex into powder for easy compounding and processing. The thermoplastic rubber developed in the 1960 s is made by the processing method of thermoplastic rubber without chemical vulcanization. Rubber can be divided into general type and special type.
Rubber wholesaler plastic original concept:
1. The main component of plastic raw materials is resin.
2. plastic raw materials: polymer synthetic resin (polymer) as the main component, penetrate into a variety of materials or additives. Plasticity and fluidity at specific temperatures and pressures. It can be molded into a certain shape and keep the shape unchanged under certain conditions.
3. Polymer: refers to the pure material or polymer material produced during the polymerization process. Both natural resins and synthetic resins are polymers, referred to as polymers.
4. Plastic has good electrical, thermal and acoustic insulation properties: excellent electrical insulation, arc resistance, heat insulation, sound insulation, sound absorption, vibration reduction and noise reduction.
Most rubber wholesalers of plastic raw materials are extracted from some oil. The common part of PC material is extracted from oil. PC material smells of gasoline when burned; ABS is extracted from coal. When ABS burns, it will exist in the form of soot; POM is extracted from natural gas. When polyoxymethylene burns, it will have a very unpleasant gas smell.
