1. Introduction

general synthetic rubber is an important polymer material, widely used in tires, hoses, tapes, seals, shock absorbers, waterproof materials and other fields. With the continuous development of science and technology, the types and performance of general synthetic rubber are also constantly improving, providing more choices and solutions for various industries.

2. the types and properties of general-purpose synthetic rubber

1. Styrene-butadiene rubber: Styrene-butadiene rubber is one of the most common general-purpose synthetic rubbers, with good wear resistance, aging resistance and processing performance. It is mainly used in tires, hoses, tapes and other fields.
2. cis-polybutadiene rubber: cis-polybutadiene rubber has excellent cold resistance, wear resistance and elasticity, and is mainly used in tires, tapes, seals and other fields.
3. ethylene propylene rubber: ethylene propylene rubber has excellent ozone resistance, weather resistance, chemical corrosion resistance and other properties, widely used in automotive parts, building waterproof, wire and cable and other fields.
4. nitrile rubber: nitrile rubber has good oil resistance, wear resistance, chemical corrosion resistance and other properties, mainly used in the production of seals, hoses, fuel tanks, etc.

3. general synthetic rubber production process

general synthetic rubber production process mainly includes emulsion polymerization and solution polymerization two methods. Emulsion polymerization is the monomer, initiator, emulsifier, etc. are added to water to form an emulsion system, and the polymerization reaction is carried out under the action of the initiator. Solution polymerization is the monomer, initiator, solvent, etc. into the reaction kettle, under the action of the initiator polymerization reaction. The two methods have their own advantages and disadvantages, and the appropriate production process can be selected according to the product use and production conditions.

4. General-purpose synthetic rubber application

1. Tire industry: General-purpose synthetic rubber plays an important role in the tire industry, which can improve the wear resistance, aging resistance, and grip of tires. Different types of general-purpose synthetic rubber can be used to make different parts of the tire to meet different performance requirements.
2. hose tape industry: general synthetic rubber can be used to make all kinds of hose and tape, with excellent wear resistance, chemical resistance and aging resistance.
3. Seals and shock absorbers: General-purpose synthetic rubber can be used to make various seals and shock absorbers, with excellent sealing performance and shock absorption performance.
4. Building waterproofing and wire and cable: General-purpose synthetic rubber is also widely used in the field of building waterproofing and wire and cable, which can improve the weather resistance, chemical resistance and electrical insulation of products. The development trend and prospect of
