Neoprene

Neoprene, a synthetic rubber produced by alpha-polymerization of chloroprene (i.e., 2-chloro-1,3-butadiene) as the main raw material, is widely used in weather-resistant products, adhesive shoe soles, coatings, and rocket fuel.

It has good physical and mechanical properties, oil resistance, heat resistance, flame resistance, sunlight resistance, ozone resistance, acid and alkali resistance, and chemical reagent resistance. The disadvantage is that it has poor cold resistance and storage stability. Has high tensile strength, elongation and reversible crystallinity, good adhesion. Resistant to aging and heat. Excellent resistance to oil and chemical corrosion. Weather resistance and ozone aging resistance is second only to ethylene propylene rubber and butyl rubber. Heat resistance is comparable to NBR, decomposition temperature 230-260℃, short-term resistance 120-150℃, long-term use at 80-100℃, with a certain degree of flame retardancy. Oil resistance is second only to NBR. Good corrosion resistance to inorganic acids and alkalis. Cold resistance is slightly poor, and electrical insulation is not good. The storage stability of raw rubber is poor, it will produce "self-sulfur" phenomenon, the viscosity of Menny increases, and the raw rubber becomes hard.
