Neoprene rubber 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 poor cold resistance and storage stability. It has high tensile strength, elongation, reversible crystallinity and good adhesion. Resistant to aging and heat. Excellent oil and chemical resistance. Weather resistance and ozone aging resistance are second only to ethylene propylene rubber and butyl rubber. The heat resistance is equivalent to that of nitrile rubber, with a decomposition temperature of 230 to 260°C, short-term resistance to 120 to 150°C, and long-term use at 80 to 100°C. It has certain flame retardancy. Oil resistance is second only to nitrile rubber. Good resistance to inorganic acid and alkali corrosion. It has slightly poor cold resistance and poor electrical insulation. The storage stability of raw rubber is poor, and "auto-sulfur" phenomenon will occur. The Mooney viscosity increases and the raw rubber becomes hard.
Raw materials for adhesive production, used for bonding metal, wood, rubber, leather and other materials. Commonly known as "universal glue".
