Neoprene rubber expansion joint
- Neoprene rubber expansion joint With high tensile strength, elongation and reversibility of crystallinity, good adhesion. Aging resistance and heat resistance. Excellent oil resistance and chemical resistance. Weathering resistance and ozone aging after ethylene propylene rubber and butyl rubber. Heat resistance and nitrile rubber, decomposition temperature of 230 to 260 DEG C, short-term can withstand 120 to 150 DEG C, in the 80 to 100 DEG C can be used for a long time, have certain flame retardant. The oil resistance of nitrile rubber after. Corrosion resistance of inorganic acid and alkali. Poor cold resistance, poor electrical insulation. Rubber poor storage stability, will have a "sulfur" phenomenon, Mooney viscosity increased, hard rubber.
