Description

Fatty Acids, Tall-Oil, Lead Salts CAS NO 61788-54-3 are metallic soaps derived from tall oil fatty acids, a by-product of the wood pulping industry, reacted with lead compounds. This product serves as a highly effective and cost-efficient heat stabilizer and lubricant in the processing of polyvinyl chloride (PVC) and other halogenated polymers. It is primarily utilized by manufacturers in the plastics, coatings, and rubber industries seeking to improve the thermal stability and processing characteristics of their formulations while managing costs.

Application

• Primary Heat Stabilizer for PVC: Used in flexible and semi-rigid PVC compounds, including cables, profiles, hoses, and films, to prevent thermal degradation during processing and extend product service life.
• Lubricant and Processing Aid: Acts as an internal/external lubricant in PVC and other polymer processing, improving flow properties, reducing sticking to metal surfaces, and enhancing surface finish.
• Stabilizer for Chlorinated Polymers: Employed in chlorinated polyethylene (CPE) and chlorinated rubber formulations to provide thermal and light stability.
• Waterproofing Agent: Used in the production of waterproof fabrics, papers, and certain construction materials.
• Drier for Paints and Inks: Functions as a polymerization catalyst (siccative) in oil-based alkyd resin paints and printing inks to promote rapid drying through oxidation.
• Grease and Thickener Component: Serves as a component in the manufacture of certain specialty lubricating greases and as a thickening agent.
