Nano-sized, highly active zinc oxide for rubber applications
The company’s products, such as LT-A501, LT-B501, and LT-A602, serve as vulcanization activators. Through a series of complex chemical reactions, these activators transform the rubber compound from a linear structure into a three-dimensional network structure, endowing the rubber with high elasticity and thereby imparting excellent physical and mechanical properties, as well as superior resistance to heat, solvents, and corrosion. This significantly enhances the utility value and application scope of rubber products.

Purpose (Function)
The company’s products, such as LT-B01, LT-A816, and LT-B816, serve as vulcanization activators. Through a series of complex chemical reactions, these activators transform the rubber compound from a linear structure into a three-dimensional network structure, endowing the rubber with high elasticity and thereby enhancing its excellent physical and mechanical properties, as well as its resistance to heat, solvents, and corrosion. This significantly boosts the utility value and application scope of rubber products. These products can be widely used in tapes, conveyor belts, V-belts, tires, and more. 
Rubber soles, rubber sheets, rubber rollers, rubber hoses, rubber mats, cables, foamed rubber products, and transparent rubber products.
Features (Advantages)
1. Relying on inorganic materials as the skeleton, we employ a mechanochemical method to modify the surface of zinc oxide nanoparticles, thereby increasing the reaction interface of the product, overcoming the agglomeration phenomenon caused by the nano-effect, ensuring the product’s vulcanization activity, and enhancing the strength of rubber products.
2. By adopting a wet-process modification technique and using organic zinc as a carrier, the product achieves more uniform dispersion within the rubber compound, improves the vulcanization system, lowers the vulcanization temperature, and accelerates the vulcanization rate. This not only enhances the inherent vulcanization activity of zinc oxide but also improves the resistance of natural rubber to post-vulcanization reversion.
3. After surface modification of zinc oxide, the reactions involving organic accelerators, stearic acid, sulfur, and other components in the rubber compound are more likely to occur on the surface of zinc oxide particles. As a result, under the action of stearic acid, zinc oxide readily forms soluble accelerator zinc salts that can dissolve in the rubber matrix, thereby enhancing its solubility and forming complexes that make the accelerators more active.
