Description

Diisotridecyl 4,4'-[(Dibutylstannylene)Bis(Oxy)]Bis[4-Oxobut-2-Enoate] is a high-performance organotin compound, specifically a dialkyltin maleate derivative, designed for demanding industrial applications. Its primary value lies in its exceptional efficacy as a heat stabilizer and catalyst, significantly enhancing the thermal processing stability and longevity of polymer materials. This product is essential for manufacturers in the PVC, polyurethane, and specialty polymer industries who require reliable additives to prevent degradation and maintain product integrity under high-temperature conditions.

Application

• Primary Heat Stabilizer for Rigid PVC: Used in the production of pipes, fittings, window profiles, and siding to prevent thermal degradation during extrusion and ensure long-term stability.
• Catalyst for Polyurethane Systems: Acts as a highly effective catalyst in the production of flexible and rigid polyurethane foams, coatings, and elastomers.
• Stabilizer for PVC Plastisols: Provides excellent heat stability in spread coatings, rotational moldings, and synthetic leather applications.
• Additive for Wire & Cable Compounds: Imparts critical thermal protection to PVC insulation and jacketing materials.
• Cross-linking Agent & Catalyst: Used in silicone rubber curing and as a catalyst in esterification and transesterification reactions.
• Stabilizer for Other Halogenated Polymers: Can be employed in formulations containing chlorinated polyethylene (CPE) or other halogen-containing resins.
