In recent years, with the rapid development of rubber industry in China, increasing the amount of calcium carbonate.


1) Tires: light calcium carbonate and nanometer calcium carbonate are partly replace low structure carbon black and silica to force car tire rubber tyre (dosage of more than 70) and rubber tube, automobile tire cord fabric rubber, air barrier in plastic, rubber and rubber inner lining layer in order to reduce the production cost. In addition, nano calcium carbonate and super zinc oxide and used instead of ordinary zinc oxide can improve the car tire tread rubber tensile strength, tensile elongation, flexural performance and fatigue resistance performance.

2) Hose and tape: light calcium carbonate and nano calcium carbonate is used in rubber hose and tape, one is white reinforcing effect of filler, 2 it is to improve the dispersity of the rubber. Calcium carbonate in rubber hose can be used in the ordinary rubber hose, color rubber hose, hydraulic hose and short fiber reinforcing rubber hose, etc., in the duct tape can be used for the conveyor belt, Chemicalbook moving belt and synchronous belt, etc.

3) Rubber shoes: calcium carbonate can adapt to different colour, can improve the sizing performance of mixing and extrusion, and they are widely used in rubber shoes with carbon black, silica, titanium dioxide and clay and used for rubber shoes uppers, soles and heels, etc.

4) Wire and cable: calcium carbonate and carbon black, silica, clay and talc powder is used for mining cable, Marine cable, high voltage wire and cable sheath and electrical wire and cable such as rubber reinforcing filler. In chlorinated rubber, such as CR, chlorinated polyethylene rubber (CM) and chlorinated butadiene rubber as main material such as wire and cable, rubber calcium carbonate, besides the reinforcing effect of filler also reduce rubber acid and absorption of hydrogen chloride produced in the process of rubber processing, thereby avoiding the phenomenon of rubber vulcanization delay and return the original function, at the same time improve the extruding performance of the rubber.
