Description

Strontium Dilaurate is a metal carboxylate salt derived from lauric acid, serving as a versatile and effective functional additive. Its primary value lies in its role as a heat stabilizer and lubricant, particularly in the processing of polyvinyl chloride (PVC) and other halogenated polymers. This compound is essential for manufacturers in the plastics, polymer, and specialty chemical industries seeking to enhance material performance and processing efficiency.

Application

• Primary Heat Stabilizer for PVC: Imparts excellent long-term thermal stability to rigid and flexible PVC formulations during processing and in the final product's service life.
• Lubricant and Processing Aid: Acts as an internal/external lubricant in PVC compounding, improving flow properties, reducing melt viscosity, and preventing sticking to processing equipment.
• Co-stabilizer in Composite Systems: Used synergistically with other metal soaps (e.g., calcium, zinc) or organic stabilizers to enhance overall stabilization performance and cost-effectiveness.
• Wire and Cable Insulation: A key component in stabilizer packages for PVC used in electrical insulation, ensuring stability under thermal stress.
• Profiles and Pipes: Critical for stabilizing PVC in construction applications such as window profiles, pipes, and siding, where weatherability and durability are paramount.
• Catalyst and Reaction Intermediate: Employed in organic synthesis and as a catalyst precursor in various chemical reactions.
• Grease and Thickening Agent: Functions as a thickener and gelling agent in the production of lubricating greases and related products.

Quality Control

Our Strontium Dilaurate is manufactured under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, metal content, and physical properties. A Certificate of Analysis (COA) detailing batch-specific results is provided to guarantee traceability, consistency, and compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from strong acids and oxidizing agents. The material is hygroscopic (moisture-sensitive); ensure containers are sealed after use to prevent moisture absorption and caking.
