Technical & commercial reference
Calcium-zinc (Ca-Zn) thermal stabiliser — how buyers specify and compare offers
A Ca-Zn one-pack is selected against a specific PVC formulation and processing window; the same designation performs differently in rigid pipe, profile and flexible compounds.
Selection
How the right grade is chosen
- Static and dynamic thermal stability results for the actual compound, not for a reference recipe
- Processing temperature window and residence time of the line
- Lubrication balance already present in the formulation — one-packs differ in internal/external lubricant content
- Risk of zinc burning at long residence times, which drives co-stabiliser choice
- Early colour hold versus long-term stability priorities
Specification
What to state in the enquiry
- Form (powder / liquid) and recommended dosage range
- Reported Congo red or oven-ageing performance with the test method stated
- Lubricant contribution of the pack
- Regulatory requirement of the end use (e.g. potable-water contact), to be resolved before selection
Procurement
Sourcing considerations
- Share the base formulation and line conditions with the enquiry; a stabiliser cannot be selected from a product name
- Plan a compound trial with plaque testing before qualification
- Request TDS and batch COA for the offered pack
- Grade, specification, documentation, packaging, availability and delivery terms are confirmed against supplier documentation with each quotation.
Comparison
Comparing competing offers
- Stability performance in the buyer's own compound
- Dosage required to reach that performance
- Effect on fusion time and output rate

About this product
Eco-Friendly Calcium-Zinc (Ca-Zn) Thermal Stabilizers — product overview
ST-CZ200 is a calcium-zinc (Ca-Zn) thermal-stabiliser system for rigid PVC extrusion. It is a lead-free alternative to legacy Pb/Ba/Cd systems, adopted globally by rigid PVC pipe, profile and sheet compounders responding to RoHS and REACH restrictions on heavy metals. Its practical role is to hold initial colour through the extrusion window and preserve outdoor weatherability across the finished profile's service life. Because rigid-PVC recipes vary in filler load, impact modifier and lubricant balance, the optimum addition rate and any co-stabiliser (e.g. β-diketones or organic co-heat-stabilisers) are formulation-specific. Grade selection, addition rate and full TDS/SDS are confirmed at RFQ against the compound and the target extruder.
Document & COA status
- • TDS: Displayed properties are an Allzone technical reference; manufacturer documentation is available on request.
- • SDS: Safety data is subject to grade and supplier confirmation. One SDS does not necessarily apply to every grade or supplier.
- • COA: Certificate of Analysis is provided against the confirmed shipment, grade and batch. No stock, lead-time or regulatory claim is implied without written confirmation.
