Tin Stabilizer for PVC

Organotin stabilizers represent an advanced generation of PVC stabilizers designed for formulations that are highly sensitive to color and heat. By precisely controlling thermal degradation reactions and neutralizing released HCl during processing, these stabilizers provide long-term thermal stability, bright initial color, and effective prevention of yellowing. Industrial Applications

Industrial Applications

Transparent PVC sheet and film Light-colored window and door profiles Transparent hoses and pipes Medical and food-grade products (depending on grade certification) High-speed calendering and extrusion processes

Formulation and Processing Notes

Tin stabilizers are incompatible with lead systems and sulfur-containing additives. High moisture levels reduce performance. Paraffin and stearate lubricants show the best compatibility. Alkaline fillers can accelerate yellowing and should be carefully controlled.
