Description

Butanedioic Acid Tin CAS NO 112131-12-1 is a specialized organotin compound derived from succinic acid, serving as a highly effective catalyst and stabilizer in advanced polymer synthesis. This compound is critical for manufacturers seeking to enhance the thermal stability and processing characteristics of polyvinyl chloride (PVC) and other polymeric materials. It is an essential raw material for the plastics, coatings, and specialty chemical industries where precise catalytic activity and material longevity are paramount.

Application

• PVC Stabilizer: Acts as a primary or co-stabilizer in rigid and flexible PVC formulations to prevent thermal degradation during processing and extend product service life.
• Polymerization Catalyst: Used as a catalyst in the production of polyesters, polyurethanes, and other condensation polymers, facilitating controlled molecular weight and structure.
• Crosslinking Agent: Employed in silicone rubber and other elastomer systems to promote crosslinking and improve final material properties like tensile strength and heat resistance.
• Lubricant Additive: Functions as an anti-wear and extreme pressure additive in advanced lubricating greases and oils.
• Coating Formulations: Imparts improved adhesion, weather resistance, and durability in high-performance industrial and marine coatings.
• Transesterification Catalyst: Catalyzes transesterification reactions, crucial in biodiesel production and the synthesis of plasticizers.

Quality Control

Our Butanedioic Acid Tin is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including assay, identification, and impurity profiling, to ensure it meets precise specifications for catalytic performance and material compatibility. Certificates of Analysis (COA) documenting purity, metal content, and other critical parameters are available upon request to support your quality assurance protocols.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed to prevent absorption of atmospheric moisture, which can affect product performance.
