Ethylene propylene rubber (EPDM), the factory code is (E)


Advantages: very good aging resistance, weathering resistance, better electrical insulation, better impact elasticity, oil resistance. Disadvantages: slow vulcanization speed, self-adhesive performance, poor hot tear performance, bad processing performance. Uses: Manufacture of heat-resistant transport belts, steam hoses, chemical-resistant seals, shock-absorbing pads and waterproof materials and automotive leather bowls, leather rings, etc.

Advantages: very good aging resistance, weathering resistance, better electrical insulation, better impact elasticity, oil resistance.

Disadvantages: slow vulcanization speed, self-adhesive performance, poor hot tear performance, bad processing performance.

Uses: Manufacture of heat-resistant transport belts, steam hoses, chemical-resistant seals, shock-absorbing pads and waterproof materials and automotive leather bowls, leather rings, etc.

2.2. Butyl rubber (NBR) factory code (N)

Advantages: excellent oil resistance, also has good heat resistance, aging resistance, wear resistance, corrosion resistance and other properties.

Disadvantages: cold resistance, acid resistance, electrical insulation and other properties are poor, and force tear strength is poor.

Uses: Mainly used in the manufacture of oil seals, shaft seals and gaskets (O-rings) and other products, can also be used to manufacture oil-resistant hoses, transport belts, rubber rollers, vacuum hoses, shock absorbing products and textile accessories.

2.3 Styrene butadiene rubber (SBR) local code (S)

Advantages: heat resistance, aging resistance and wear resistance are better.

Disadvantages: cold resistance, elasticity, flexural disturbance, cracking, tearing resistance and other properties are poor, and processing performance is poor plasticity change is small, calendering press out deformation, poor self-adhesion.

Uses: mainly used for pneumatic tires, followed by rubber shoes, hoses, tapes, rubber rollers, rubber cloth and model products, vacuum cleaner seals, such as suction mouth seals, etc.

2.4 neoprene (CR), the factory code (C)

Advantages: good resistance to flexural disturbance, heat resistance, aging resistance, acid and alkali resistance, etc., and good elasticity, good air tightness. It has cold resistance and water resistance.

Disadvantages: storage stability is poor, easy to crystallize, electrical insulation is poor

Use: Mainly produce rubber parts in home appliances and air conditioners

2.5 Butadiene rubber or polybutadiene rubber (BR)

Advantages: elasticity, low temperature resistance, wear resistance is better.

Disadvantages: tensile strength, tear strength is low, resistance to wet slippage is not good, poor adhesion.

Uses: mainly used in the manufacture of tires, can also be used to manufacture wear-resistant products (such as rubber shoes, rubber rollers), cold-resistant products and shockproof products.

2.6 Butyl rubber (IIR), the factory code (I)

Advantages: the most important feature is good air tightness, weather aging, light aging, chemical resistance are excellent, and high temperature resistance, cold resistance is better, long-term working temperature can be below 130 ℃; shock absorption or shock absorption effect is better, electrical insulation is better.

Disadvantages: less elastic than natural rubber, slower vulcanization speed, processing performance, poor adhesion.

Uses: Most suitable for inflatable inner tube, followed by underground cables, high-voltage cables, radiation-proof gloves, chemical equipment lining and shockproof rubber products, etc.

Introduction to the composition and classification of rubber conveyor belts

Composition of rubber conveyor belt, conveyor belt consists of upper and lower cover rubber and belt core. Classification of rubber conveyor belt:According to the rubber surface classification:heat resistant, acid and alkali resistant, cold resistant, oil resistant, flame retardant, anti-static, etc.;According to the core classification:common fabric conveyor belt, steel cord conveyor belt. Rubber conveyor belt is generally used in chemical, coal and other industries, which belongs to heavy conveyor belt and is also a kind of consumable. Therefore, when using rubber conveyor belt, you should also pay attention to the daily maintenance, avoid hard objects to bruise, avoid sun and rain, and don't put it together with oiled items. So, what is the composition and classification of rubber conveyor belt?

Rubber Conveyor Belt

Commonly used types of patterned conveyor belts are as follows: 1. Herringbone pattern Features: There is a "herringbone" pattern on the belt surface, which is higher than the belt body, the pattern can be open or closed, and each pattern can be divided into high, medium and low. Application: It is suitable for conveying powder, granule and small pieces of materials with an inclination of ≤40 degrees, and can also convey bagged materials.
