Description

Tin(II) Stearate is a white, waxy solid belonging to the class of metal carboxylates. This compound serves as a versatile and effective catalyst, stabilizer, and lubricant in various polymerization and plastics processing applications. It is particularly valued in the PVC industry for its heat stabilizing properties and in the production of polyurethane foams. Industries such as plastics manufacturing, polymer synthesis, and specialty chemical production rely on this material for its consistent performance.

Application

• PVC Heat Stabilizer: Acts as a secondary stabilizer or co-stabilizer in polyvinyl chloride (PVC) formulations to prevent thermal degradation during processing.
• Polyurethane Catalyst: Used as a catalyst in the production of flexible and rigid polyurethane foams, promoting the gelling reaction.
• Polymerization Catalyst: Functions as a catalyst in various esterification and polymerization reactions.
• Lubricant & Release Agent: Provides internal and external lubrication in plastics processing, improving flow and mold release.
• Water Repellent: Imparts hydrophobic properties to textiles, paper, and construction materials.
• Cosmetics & Personal Care: Used as an opacifying agent and texture modifier in certain cosmetic formulations.

Quality Control

Our Tin(II) Stearate is manufactured under strict quality management protocols. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, metal content, and physical properties. A comprehensive Certificate of Analysis (COA) detailing assay, moisture content, melting point, and heavy metal limits is provided with every shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and should be kept under dry conditions to prevent caking and degradation. Keep away from strong oxidizing agents.
