Polymers
PVC Stabilizers
Formula:
3PbO · PbSO4 · H2O
GOST/CAS:
Соответствует стандартам предприятия и международным нормам безопасности.
Complex stabilizers are balanced blends of metal salts, antioxidants, and lubricants. They are designed to prevent the thermal degradation of PVC during processing at high temperatures and shear stress, ensuring long-term stability and color retention in finished products.
Applications
PVC Profiles & Fittings: Used in the extrusion of window profiles, windowsills, and siding to provide structural rigidity and UV resistance.
Cable Industry: Applied in cable insulation compounds to ensure high dielectric properties and heat resistance.
Pipes & Tubes: Ensures dimensional stability and a smooth internal surface for pressure and sewage pipes.
Sheets & Films: Enables the production of high-clarity or uniformly colored materials by preventing pigment "burning."
Key Advantages
Synergistic Effect: The precisely formulated ratio of components replaces multiple individual additives, simplifying the dosing process.
High Thermal Stability: Effectively neutralizes released hydrogen chloride, preventing the polymer from darkening or becoming brittle.
Improved Processability: Reduces melt viscosity, which lowers the load on the extruder motor and increases production line output.
Eco-Friendly Options (Ca-Zn series): Heavy metal-free formulations suitable for products in contact with food or drinking water.
Storage & Transportation
- Store in a cool, dry, well-ventilated area away from direct sunlight.
- 12–24 months from the date of manufacture.
