Description

Bis(6-Hydroxystearic Acid)Calcium Salt is a specialized metallic soap derived from hydroxystearic acid, functioning as a versatile processing aid and stabilizer in polymer systems. Its primary value lies in its ability to act as an effective acid scavenger and lubricant, enhancing the thermal stability and processing characteristics of various materials. This compound is essential for manufacturers in the plastics, rubber, and coatings industries seeking to improve product quality and production efficiency.

Application

• Polymer Stabilizer: Acts as an acid acceptor and heat stabilizer in polyvinyl chloride (PVC) and other halogenated polymers to prevent degradation during processing.
• Internal Lubricant: Improves the flow properties and mold release characteristics of engineering plastics and thermoplastic compounds, reducing processing energy.
• Rheology Modifier: Used in grease and lubricant formulations to control consistency and provide structural stability.
• Coating Additive: Enhances the dispersion of pigments and fillers in paint and coating systems, improving finish quality.
• Rubber Processing Aid: Facilitates the mixing and calendering of rubber compounds, acting as a peptizer and homogenizing agent.
• Adhesive & Sealant Component: Imparts thixotropic properties and improves the thermal aging resistance of adhesive formulations.
