Wuhan Handern General Synthetic Rubber
1. Styrene-butadiene rubber This is a rubber composed of butadiene and styrene. www.handern.com Building plastic formwork
There are many types, mainly styrene 10, styrene -30, styrene 50-(the following figures indicate the mass fraction of styrene content). The higher the styrene content, the better the solvent resistance, but the elasticity decreases, the plasticity increases, the corrosion resistance is better, and the hardness increases. In addition, styrene-butadiene rubber has better wear resistance, heat resistance, oil resistance and aging resistance than natural rubber, and can be mixed with natural rubber in any ratio, and the price is low. Disadvantages are low raw rubber strength, poor adhesion, difficult molding, slow curing speed, and tires made less elastic than natural rubber. Styrene-butadiene rubber is mainly used in combination with other rubbers, and can replace natural rubber to manufacture tires, tape hoses, rubber shoes, etc. www.handern.com Building plastic formwork
2. Butadiene rubber This is a rubber made from butadiene polymerization. www.handern.com Building plastic formwork
Its elasticity, resistance, heat resistance and cold resistance are superior to natural rubber, and it is an excellent material for manufacturing tires. The disadvantages are lower strength, poor processing performance, and poor tear resistance. Mainly used for manufacturing tires, but also for manufacturing adhesive tapes, springs, shock absorbers, heat-resistant hose electrical insulation products, shoe soles, etc. www.handern.com Building plastic formwork
3. Neoprene It is a rubber made of chloroprene polymerized. www.handern.com Building plastic formwork
Neoprene not only has high elasticity, high insulation, high strength and high alkali resistance comparable to natural rubber, but also has excellent properties that natural rubber and general general rubber do not have, that is, oil resistance, solvent resistance, Oxidation resistance, aging resistance, acid resistance, heat resistance, combustion resistance, deflection resistance and other properties, so it is called "universal rubber". www.handern.com Architectural plastic formwork can be used as both general rubber and special rubber The disadvantages are poor cold resistance, high density, and poor raw rubber stability. Neoprene is widely used. Because it is resistant to combustion, it can emit HC gas to prevent combustion once it is burned, so it can be used to make conveyor belts, air pipes, and cables for underground mines. It can also be used as a pipeline to transport oil or corrosive media, as well as heat-resistant conveyor belts, high-speed V-belts, and various mat drawings. www.handern.com Building plastic formwork
4. Ethylene propylene rubber This is a rubber made of ethylene and propylene. www.handern.com Building plastic formwork
Ethylene-propylene rubber is stable in structure, has excellent anti-aging properties, and its ability to resist ozone is more than 100 times higher than that of ordinary rubber, and its ability to weather and resist sunlight aging is also strong. In addition, the ethylene propylene rubber has good insulation, heat resistance and cold resistance. The use temperature Shi Guokuan (-60- + 150 ℃) can be applied even at -68 ℃. Its chemical stability is also very good. It has great corrosion resistance to various polar chemicals and acids and alkalis, but it has poor stability to hydrocarbon oils. Its main disadvantages are slow curing speed and poor adhesion. Usually used to make tires, steam hoses, adhesive tapes, heat-resistant conveyor belts, sealing rings, heat dissipation hoses, high-voltage wire sheaths, etc. www.handern.com Building plastic formwork
