Dimethyltin dineodecanoate

Dimethyltin dineodecanoate (CAS 68928-76-7) is an organotin compound used as a heat stabilizer and catalyst in polymer processing.

Where is Dimethyltin dineodecanoate used?

• PVC and thermoplastics: protection from thermal degradation during high-temperature compounding and extrusion
• Rigid and flexible PVC: prevention of discoloration and chain degradation in pipe, profile and film production
• Polyurethane and silicone systems: catalyst accelerating cure rates in industrial coatings and sealants
• Rubber compounding: improved processing stability
• It extends service life in finished elastomeric components.
• Specialty polymers: long-term stabilization against oxidative and thermal breakdown

Good to know: Buyers sourcing for sensitive or regulated applications should confirm tin content and compatibility with their specific formulation system.

Commercial specifications

• Liquid, typically in bulk drums or intermediate bulk containers
• Purity specifications aligned to polymer and rubber processing requirements
