Powder Calcium-Zinc Product Features
1.Lubricity & Flowability
Excellent lubricity and flowability ensure superior processability, even under harsh processing conditions (e.g., high-temperature extrusion or high-shear molding).
2.Unique Structure & Thermal Stability
Features a novel molecular structure with outstanding heat resistance, effectively suppressing thermal decomposition of PVC during processing.
3.Color Stability
Provides excellent initial color retention and long-term heat resistance, maintaining consistent color performance over time.
4.Printing Adhesion
Ensures superior surface printing adhesion and strong ink compatibility, with no ink detachment issues in high/low temperature environments (e.g., -40°C to 80°C).
5.Formulation Compatibility
Works seamlessly with various PVC (formulation systems), preventing blooming, migration, and sulfur contamination in finished products.
6.Odorless & Antioxidant
Offers excellent antioxidant properties and is completely odorless, meeting strict hygiene requirements for food-contact applications.
Application Fields
Calcium-zinc and barium-zinc heat stabilizers are synthesized via a special compounding process using calcium salts, zinc salts, lubricants, and antioxidants as key components. They deliver:
Exceptional thermal stability, light stability, transparency, and colorability
Ideal for rigid/flexible PVC products requiring high visual and mechanical performance
