Our day by day lives are beyond belief without the immensely stretchable material rubber. By rubber, we comprehend vulcanized natural or engineered rubbers, for example, styrene-butadiene (SBR), nitrile-butadiene (NBR), and ethylene-propylene-diene (EPDM). The applications for rubber-based polymers can be found any place versatility is of exceptional significance, for example in floor covers, tires, hoses, conveyer belts, cables, and different family items.

Being profoundly weather-resistant and chemically inert, kaolin is considered an ideal additive to rubber because of its anisometric ‘booklet’ molecule structure which adds strength and solidness to the material through improved pressure move. Kaolin clay AKA China Clay is a minimal expense substitute for precipitated silica and carbon-black in specific compounds without forfeiting actual physical properties.

Kaolin Clay is utilized to enhance the modulus and tensile of ground calcium carbonate based rubber compounds. ‘Soft’ kaolin has bigger grain measures and are utilized where high loadings (for economy) and quicker expulsion rates are a higher priority than strength. ‘Hard’ kaolin clay with more modest molecule sizes proclaims high modulus, high rigidity, solidness, and great abrasion resistance to rubber compounds. 80% of the clays utilized in rubber creation are Air Float hard clays, which are air isolated to eliminate pollutants. Surface-treated hard clays give shockingly better support than untreated clays and have the ability to substitute carbon-black in specific applications.

Uncommon functionalities, for example, improved air-penetrability can be proclaimed in hydrous kaolin through the interaction of delamination. Calcined kaolin or water-washed clay is utilized in specific applications, for example, wire and cable production as it gives great support, higher volume resistivity, and better color.
