What is the difference between nitrile rubber and neoprene?

Difference: Cyanobutadiene rubber has good oil resistance, heat resistance and abrasion resistance. Neoprene rubber is not afraid of direct sunlight, has excellent atmospheric aging resistance, and is not afraid of severe distortion.
1. Cyanobutadiene rubber
It is made of butadiene and acrylonitrile by lotion polymerization. Cyanobutadiene rubber is mainly produced by low temperature lotion polymerization. It has excellent oil resistance, high abrasion resistance, good heat resistance and strong adhesion. Its disadvantages are poor low temperature resistance, poor ozone resistance, poor electrical performance, and slightly low elasticity.
Cyanobutadiene rubber is mainly used to manufacture oil resistant rubber products.
2. Neoprene
(Synthetic polymer compound) is made of chloroprene as the main raw material through homopolymerization or copolymerization of a small amount of other monomers. For example, high tensile strength, excellent heat resistance, light resistance, aging resistance, and oil resistance are superior to natural rubber, styrene butadiene rubber, and cis polybutadiene rubber. It has strong flame resistance and excellent flame retardancy, high chemical stability and good water resistance.
The disadvantages of neoprene rubber are electrical insulation, poor cold resistance and instability of raw rubber during storage. Neoprene is widely used, such as to make transportation belts and transmission belts, wire and cable sheathing materials, oil resistant rubber tubes, gaskets and chemical resistant equipment linings.
Neoprene rubber is made from 2-chloro-1,3-butadiene monomer through lotion polymerization. It can be modified with sulfur and 2,3-dichloro-1,3-butadiene (ACR).
Neoprene can be used in different technical fields, mainly in the rubber industry (61%). However, it is also very important as the raw material of the adhesive, and has different applications (6%), such as impregnated products (such as gloves), molded foam materials, asphalt modification, etc.
