Nano calcium carbonate cas no 471-34-1

Calcium carbonate 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.
