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)

Cd ≤ 100 ppm, Pb/Hg/Cr(VI)/PBBs/PBDEs ≤ 1000 ppm, ND in tests

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.
