In the rubber sulfur vulcanization system, in addition to various organic accelerators, zinc oxide is an essential inorganic active agent. Adding accelerators alone cannot achieve the best vulcanization effect. The activation system composed of zinc oxide, stearic acid, and accelerators (M/D/TS) has been a classic formula used in the rubber industry for many years.
Indirect method with 99.7% zinc oxide, high purity, low heavy metal impurities, uniform powder size, and excellent dispersibility during mixing. Its core function is to form zinc soap with stearic acid, activate the vulcanization accelerator, accelerate the vulcanization speed, improve the cross-linking density of rubber compound, significantly improve the tear strength, abrasion resistance and aging resistance of rubber, optimize the dynamic heat generation, and enhance the adhesive strength of rubber with steel cord and nylon skeleton material, which is very suitable for radial tire, thick section shock absorption rubber, conveyor belt and other products under dynamic working conditions.
High activity zinc oxide, with its larger specific surface area, can be used in formulations in reduced quantities, which is in line with the industry's development direction of zinc reduction, carbon reduction, and green production, and meets the environmental protection limits for overseas export products.
The current export orders in the rubber industry are increasing, and overseas customers have continuously raised their requirements for testing zinc oxide heavy metals, insoluble substances, and purity indicators. The market competitiveness of zinc oxide products with low impurities and stable batches is stronger. The industry is also continuously exploring zinc reduction formulas, reducing the total amount of zinc added while ensuring that the physical properties of rubber remain unchanged, and adapting to international environmental regulations.
Our company can provide rubber grade high-purity indirect method zinc oxide and activated zinc oxide, strictly controlling key indicators such as purity, heavy metals, and screen residue. The batch is stable and comes with TDS and MSDS testing data. We supply to domestic rubber factories and foreign trade customers. Welcome new and old customers to inquire and request samples by phone.
