Calcium-Zinc Heat Stabilizers
for PVC & CPVC
Heavy-metal-free Ca/Zn stabilizer systems for rigid and flexible PVC processing — engineered for clarity, weatherability, and long-term regulatory compliance (RoHS / REACH). Supplied in granule, powder, and one-pack forms — ready-to-use blends that simplify dosing, reduce mixing errors, and improve batch consistency on your extrusion, calendering, or injection line.
Product forms
One chemistry, three deliverable forms
Each form is built on the same Ca/Zn base and adjusted for your intake equipment and dosing method.
Calcium-Zinc Heat Stabilizers for PVC & CPVC — Granule
Free-flowing granules for direct metering on extrusion and injection lines — low dust, consistent bulk density, easy automatic dosing.
Calcium-Zinc Heat Stabilizers for PVC & CPVC — Powder
Fine powder for compounding and masterbatch production — fast dispersion, suited to internal mixers and high-shear compounding.
Calcium-Zinc Heat Stabilizers for PVC & CPVC — One-Pack
One-Pack Ca-Zn stabilizers combine stabilizing additives in a ready-to-use blend, simplifying dosing, reducing mixing errors, and improving batch consistency.
Application field
Where CIVAL Ca/Zn stabilizers are specified
