Description

Strontium Didocosanoate is a strontium salt of behenic acid, a long-chain fatty acid, with the CAS registry number 14987-70-3. This specialty metal soap is valued for its role as a high-temperature stabilizer and lubricant in polymer processing. It is primarily utilized by manufacturers in the plastics and rubber industries seeking to enhance the thermal stability and processing characteristics of their materials.

Application

• Polymer Stabilizer: Acts as a heat stabilizer and lubricant in the processing of polyvinyl chloride (PVC) and other halogenated polymers.
• Plastics Additive: Used in rigid and flexible PVC formulations to improve long-term thermal stability during extrusion and molding.
• Rubber Industry: Functions as a processing aid and release agent in the manufacture of various rubber compounds.
• Grease and Lubricant Thickener: Serves as a component in the formulation of high-temperature greases and specialty lubricants.
• Cosmetics and Personal Care: May be employed as an opacifying agent or viscosity modifier in certain cosmetic formulations.
• Surface Coatings: Used as a flatting agent or matting agent in paints and varnishes to control gloss.
