Packed in kilograms/bag, inner packaging is plastic bag and outer packaging is woven bag. 6. Preparation method of stearic acid: High-quality stearic acid is obtained by high-pressure hydrolysis of solid fat, washing with acid and alkali water, and then treatment.
7. Application of stearic acid: High-quality stearic acid has good mutual solubility with natural rubber and synthetic rubber (except butyl), which can promote the uniform dispersion of carbon black, zinc oxide and other compounding agents in the rubber compound. It can also react with zinc oxide or alkaline accelerator to increase activity. Stearic acid can also be used in stearic acid esters and salt catalysts, soap lubricants, pharmaceutical and cosmetic dispersants and softeners, metal polishing pastes, protective coatings and food packaging industries.
8. Product application fields:
Plastic industry
Stearic acid is widely used in the manufacture of plastic pipes, plates, profiles, and films. Domestic stearic acid has good lubricity and good light and heat stability. High-quality stearic acid in plastic tubes. Stearic acid helps prevent coking during processing. Tertiary stearic acid is an effective heat stabilizer when added during film processing. High-quality domestic stearic acid also protects against exposure to vulcanization. Discoloration of the finished film caused by chemicals.
Rubber Industry
Stearic acid plays an important role in the synthesis and processing of rubber. Tertiary stearic acid is a widely used vulcanization active agent in natural rubber, synthetic rubber and latex. Stearic acid can also be used as a plasticizer and softener. In the process of producing synthetic rubber, domestic stearic acid needs to be added as an emulsifier. When manufacturing rubber, tertiary stearic acid can be used as a foaming agent. High-quality stearic acid can also be used as a release agent for rubber products.
