Introduction to the Basic Composition and Properties of Rubber Material Used in Conveyor Belt

Conveyor belt rubber is mainly composed of macromolecule materials. Below Jingbo Rubber gives you a brief introduction of several commonly used rubber raw materials for conveyor belt, so that you will have some more professional knowledge in the purchase of conveyor belt.

1. Styrene-butadiene rubber, abbreviated as SBR in English. Styrene-butadiene rubber (SBR) is a kind of rubber material commonly used in conveyor belt. Styrene-butadiene rubber (SBR) has a general strength and needs to be reinforced by some materials, such as carbon black. Styrene-butadiene rubber has better heat resistance, wear resistance and aging resistance than other materials. Elasticity and tear resistance are poor.

2. Nitrile-butadiene rubber, abbreviated as NBR in English, is generally used in the manufacture of oil-resistant conveyor belts. The oil resistance of NBR is good, and its aging resistance and heat resistance are better than those of NR and SBR.

3. Natural rubber, abbreviated as NR in English. Natural rubber has good elasticity and high resilience. Generally, the resilience of natural rubber can reach 70% - 80%, and the elongation can reach 1000%. Natural rubber has high strength and excellent flexibility resistance, which is the first choice of rubber raw materials.

Ethylene propylene rubber (EPDM), abbreviated as EPDM, can be said to be one of the best commonly used rubber raw materials with excellent performance. Ethylene propylene rubber has good impact resistance, low temperature resistance, chemical corrosion resistance and  good resilience.

Above are several kinds of rubber materials commonly used in conveyor belts introduced by Baoding Jingbo Rubber Company. When purchasing conveyor belts, it is better to ask which is the raw material of conveyor belts, so as to select a more suitable conveyor belt.
