Description

Dioctyltin(IV) Maleate, Polymer is a high-performance organotin compound widely recognized for its exceptional thermal stabilizing properties. This product is a critical additive in the manufacturing of polyvinyl chloride (PVC) and other halogenated polymers, where it effectively prevents degradation during high-temperature processing. It is an essential material for producers of rigid and flexible PVC products, synthetic leather, and wire & cable insulation seeking to enhance product longevity and performance.

Application

• Primary heat stabilizer for rigid and flexible polyvinyl chloride (PVC) formulations.
• Critical additive in the production of PVC pipes, fittings, and profiles for construction and industrial applications.
• Stabilizing agent for PVC films, sheets, and synthetic leather to prevent thermal degradation during calendering and extrusion.
• Essential component in wire and cable insulation compounds to ensure long-term thermal stability.
• Used as a catalyst or co-catalyst in specific polyurethane (PU) and silicone rubber curing systems.
• Stabilizer for other halogen-containing polymers beyond PVC.
