Calcium-Zinc Stabilizer for SPC, also known as Ca-Zn Stabilizer for SPC Flooring, is a high-performance PVC heat stabilizer developed for stone plastic composite flooring. It combines calcium and zinc soap systems with selected co-stabilizers, antioxidants, and lubricants. This formulation absorbs hydrogen chloride and replaces unstable chlorine atoms in PVC. As a result, it prevents thermal degradation and discoloration during the high-temperature processing of SPC core layers. Its excellent compatibility with high calcium carbonate loadings and PVC resins helps manufacturers produce cleaner, safer, and more sustainable SPC flooring.
Where It Performs
In the SPC flooring industry, Calcium-Zinc Stabilizer supports rigid PVC core layers, click-lock planks, rigid vinyl tiles, and related stone plastic composite profiles. It performs well in extrusion, calendering, lamination, embossing, annealing, and downstream cutting or slotting processes. Furthermore, it helps maintain initial whiteness, color consistency, surface finish, mechanical properties, and dimensional stability in high-filler SPC systems.
Processing Advantages
Calcium-Zinc Stabilizer for SPC offers a broad processing window. It performs well in high-speed extrusion and calendering lines for rigid SPC flooring. In addition, it is compatible with calcium carbonate, processing aids, lubricants, pigments, and other additives. Therefore, formulators can achieve the right balance of stability, lubrication, melt flow, and cost efficiency. It also helps reduce plate-out, discoloration, and surface defects during continuous production. Available forms include powder, flake, and liquid. You can also request lubricating or non-lubricating grades, as well as custom grades for SPC core formulations.
Safety and Compliance
What makes TOPLUS® Calcium-Zinc Stabilizer truly remarkable is its ability to combine safety and performance. It contains no lead and no cadmium, and it delivers low odor and low migration. Depending on the grade, it can support compliance with RoHS, REACH, EN71-3, and other restricted-substance requirements commonly requested for flooring applications. However, it is an industrial additive for PVC and SPC processing, not a food additive. Therefore, customers should confirm actual compliance against the specific grade and certification.
Why Choose It
Choose TOPLUS® Calcium-Zinc Stabilizer for SPC for its versatility, reliability, and superior performance in rigid stone plastic composite flooring. Trust it to deliver consistent, high-quality results every time. In short, it is a premium, lead-free heat stabilizer designed for SPC flooring production. It delivers excellent thermal stability, outstanding initial color, and reliable long-term performance. Consequently, it provides an ideal eco-friendly alternative to traditional lead-based stabilizers.
