Endowed with properties like alkalinity and filling capacity, calcium hydroxide can exert multiple pivotal functions when used as an industrial additive in the rubber and plastic sectors.

Rubber Industry

Neutralization and Impurity Removal: Trace acidic impurities may remain in rubber production raw materials, such as natural rubber latex and synthetic rubber monomers. These impurities can undermine the stability of rubber and the effectiveness of vulcanization. Thanks to its alkalinity, calcium hydroxide is capable of neutralizing acidic substances and eliminating impurities. This not only ensures the smooth progression of subsequent rubber processing procedures but also prevents acidic substances from impairing the performance of rubber products.

Assisting Vulcanization and Performance Regulation: During the rubber vulcanization process, calcium hydroxide can act as an activator or auxiliary accelerator. When used in conjunction with vulcanizing agents and accelerators, it enhances vulcanization efficiency and promotes more uniform cross - linking of rubber molecules. Additionally, as an inorganic filler, it can be appropriately incorporated into the rubber matrix. While cutting down on costs, it also improves the hardness, wear resistance and aging resistance of rubber products to a certain extent. It is commonly utilized in the manufacturing of rubber products including tires, seals and rubber hoses.

Enhancing Compound Processability: The fine powder property of calcium hydroxide can optimize the mixing performance of rubber compounds. It enables the even blending of various components, mitigates the adhesion issue of compounds during mixing and molding processes, and thereby boosts production efficiency.

Plastic Industry

Core Application in the PVC Industry: Calcium hydroxide is a crucial auxiliary additive in the production of polyvinyl chloride (PVC). When processing PVC resin, residual vinyl chloride monomers in raw materials or slight decomposition occurring during the processing may generate acidic substances. Calcium hydroxide can neutralize these acidic components, which prevents PVC products from degradation, discoloration, embrittlement and other problems caused by acid corrosion, thus extending the service life of the products. Meanwhile, it can be used as a filler for PVC products to reduce raw material costs. It also enhances the heat resistance and dimensional stability of PVC materials, and is frequently employed in the production of PVC pipes, sheets, profiles and other products.

Auxiliary Modification for Other Plastics: In some thermoplastic or thermosetting plastics, calcium hydroxide can be used as a functional filler in combination with other additives. It not only lowers production costs but also improves the flame retardancy and weather resistance of plastics. For instance, in certain plastic components used outdoors, the addition of calcium hydroxide can reduce the corrosion of plastics by acidic substances in the environment and slow down the aging process.

The applications of calcium hydroxide :

• Flue Gas Desulfurization: Widely used for exhaust gas treatment in power plants.

• Water Treatment: Effective in water purification and sewage treatment processes.

• Industrial Use: Widely used in the construction, environmental protection, and chemical industries.
