Description

Dibutyltinbis(N,n-Diethyldithiocarbamate) is an organotin compound that functions as a highly effective heat stabilizer and catalyst. This product is critical for enhancing the thermal processing stability and long-term performance of various polymer systems. It is primarily needed by manufacturers in the PVC, polyurethane, and silicone industries seeking to improve product durability and processing efficiency.

Application

• Primary Heat Stabilizer for PVC: Used in rigid and flexible PVC formulations, including pipes, profiles, cables, and films, to prevent thermal degradation during processing and extend service life.
• Catalyst for Polyurethane Foams: Acts as a gelling catalyst in the production of flexible, semi-rigid, and rigid polyurethane foams, promoting optimal reaction kinetics and foam structure.
• Cross-linking Agent for Silicone Rubbers: Employed as a catalyst in condensation-cure (tin-catalyzed) RTV-1 and RTV-2 silicone rubbers for adhesives, sealants, and molds.
• Lubricant Additive: Functions as an anti-wear and extreme pressure (EP) additive in industrial lubricants and greases.
• Stabilizer for Other Polymers: Provides thermal stabilization for other halogen-containing polymers and certain engineering plastics.
• Biocide Synergist: Used in combination with other biocides in material protection applications, leveraging its organotin properties.
