Key Benefits
Low-odor, no blooming/plate-out, reduced heavy-metal residues
Strong heat stability, good light/long-term color stability
Works across calendering, sheet/film extrusion and blown film
RoHS-compliant (IEC 62321; full reports available on request)
Can reduce methyl-tin usage by ~30–60% depending on your quality targets and formulation; proven to lower overall processing cost
Typical Composition (guidance)
Calcium content: 8 ± 0.5 %
Zinc content: 19 ± 0.5 %
Typical Properties (reference values)
Melting range: 80–150 °C (GB 617-88)
Moisture: ≤ 2.0 % (GB/T 1034-1998) → 0.16 % (typ.)
Loss on heating: ≤ 2.5 % (ASTM D6980-09) → 0.55 % (typ.)
Compliance (RoHS / Restricted Substances)

Bisphenol A / Phenol: method-based limit 10 → ND
Documentation pack available upon request.
Recommended Use:
Begin near your current methyl-tin dosage and reduce 30–60% with Y-550 as the stabilizer backbone; finalize phr on line. Maintain a flat torque curve by fine-tuning internal/external lubricants and monitor die-lip cleanliness.
Typical Applications:
Rigid PVC calendered sheets & films, profile/pipe extrusion, blown-film operations.
Powder Calcium-Zinc (Ca-Zn) PVC Stabilizer
Lead-free performance for modern PVC processing.
Our powder Calcium-Zinc (Ca-Zn) stabilizers deliver thermal stability and clean processing without the heavy metals found in legacy systems. Formulated with sustainability in mind, they support high output, consistent color, and durable end-use properties across a wide range of PVC applications.
Why Choose Ca-Zn Stabilizers
Heavy-metal free: No lead, cadmium, barium, or organotin.
Compliance ready: Formulations available to support REACH and RoHS documentation.
Strong thermal stability: Maintains integrity under elevated processing temperatures.
Smooth processing: Balanced lubricity and dispersion for stable torque, clean die lips, and fewer changeovers.
Reinforced properties: Excellent coupling action that improves weld strength and overall mechanical performance.
Typical Applications
Wires & cables – reliable insulation and long service life.
Window & technical profiles – including foamed profiles with stable color and surface quality.
Pipes & fittings – soil and sewer pipes, foam-core pipes, land drainage, pressure pipes, corrugated pipes, and cable ducting, plus matching fittings.
What You Can Expect in Production
Fast start-ups with stable torque and minimal plate-out.
Consistent whiteness and gloss retention where required.
Good flow and dispersion in both extrusion and calendering.
Support for food-contact or low-odor targets (on request, depending on grade).
Documentation & Support
Compliance statements (e.g., RoHS/REACH) and lab data are available on request. Our technical team can recommend the right Ca-Zn grade and optimize phr & lubrication balance for your line.
