Description

Hydroxydimethyltin Oleate is an organotin compound that functions as a highly effective catalyst and stabilizer in various polymerization processes. Its unique structure provides excellent thermal stability and catalytic activity, making it a critical component for manufacturers seeking consistent and high-quality polymer outputs. This product is essential for industries involved in the production of polyurethane foams, PVC stabilizers, and silicone elastomers, where precise reaction control and material longevity are paramount.

Application

• Primary catalyst for the production of polyurethane (PU) foams, including flexible, rigid, and integral skin foams.
• Heat stabilizer and lubricant in polyvinyl chloride (PVC) processing for pipes, profiles, and films.
• Catalyst for silicone room-temperature vulcanization (RTV) and condensation cure systems.
• Intermediate in the synthesis of other organotin compounds used as biocides or polymer additives.
• Cross-linking agent and catalyst in esterification and transesterification reactions.
• Additive for improving the thermal and light stability of various polymeric materials.

Quality Control

Our Hydroxydimethyltin Oleate is manufactured under strict quality management systems to ensure batch-to-batch consistency and reliability. Each lot undergoes comprehensive analysis, including assay, identification, and impurity profiling. A Certificate of Analysis (COA) detailing all test results is provided with every shipment. We can support compliance with relevant standards such as REACH and other global regulatory frameworks upon request.

Storage

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