6642 31 5 Overview

CAS No. 6642-31-5 (often referenced as cas no 6642 31 5) is an organic additive widely adopted as a co-stabilizer in calcium–zinc systems for PVC and other chlorine-containing polymers. Within Polymer material additives, it enhances Plastic heat stabilizer packages by improving initial color, lengthening thermal stability time, and helping to control HCl evolution during processing. In practical terms, it supports cleaner processing, a wider operating window, and more consistent product quality across extrusion, calendaring, and injection-molding lines.

From a technical standpoint, 6642 31 5 is valued for its compatibility with Ca–Zn stabilizers, organophosphites, ESBO, and selected lubricants. Typical use levels are low (commonly 0.2–0.6 phr depending on formulation and substrate), enabling formulators to optimize cost and performance. Many processors prefer its fine particle size and easy dispersion, which contribute to uniform stabilization and reduced plate-out tendencies. HEBEI GUANGXING CHEMICAL INDUSTRY CO., LTD. manufactures and supplies this material with rigorous quality control, providing consistent purity, reliable lead times, and technical support tailored to B2B decision makers who manage complex PVC product portfolios.

Benefits & Use Cases of 6642 31 5 in Plastic heat stabilizer

In Plastic heat stabilizer systems, 6642 31 5 serves as a performance amplifier for Ca–Zn packages. It is used across rigid and flexible PVC: window profiles, siding and trim, pipes and fittings, cable insulation and sheathing, calendared films and sheets, flooring, and injection-molded parts. By promoting better control over thermal degradation, the additive helps maintain brightness, reduces yellowing, and stabilizes melt viscosity during long production runs. These attributes translate into fewer off-spec reels, less scrap, and more predictable start-up and color hold.

Key advantages for B2B processors include low dosage efficiency, strong synergy with calcium–zinc stabilizers, and compatibility with common plasticizers and co-additives. Compared with conventional approaches, many users observe cleaner dies and screws, less plate-out, and improved gloss on finished parts. HEBEI GUANGXING CHEMICAL INDUSTRY CO., LTD. brings deep formulation know-how to help customers right-size dosage, balance lubrication, and pair 6642 31 5 with the appropriate stabilizer backbone for region-specific regulations and target mechanical/optical performance.

Cost, Maintenance & User Experience

Total cost of ownership matters for high-throughput PVC lines. Because 6642 31 5 works effectively at low phr, it can reduce the overall stabilizer cost while preserving or improving heat stability. Better color retention and a wider processing window help cut scrap rates and shorten changeovers, which improves line utilization. Process cleanliness—manifested as reduced plate-out and fewer unplanned purges—lowers maintenance hours and helps protect tooling, further supporting ROI for converters and compounders.

Feedback from Polymer material additives customers typically highlights smoother start-ups, more stable torque profiles, and improved lot-to-lot consistency after adopting CAS No. 6642-31-5 in Ca–Zn stabilizer packages. While results vary by formulation and equipment, many users value the additive’s ability to deliver predictable processing and consistent product aesthetics across long runs. HEBEI GUANGXING CHEMICAL INDUSTRY CO., LTD. complements the product with application support, helping teams evaluate TCO through tailored trials and data-driven optimization.

Sustainability & Market Trends in chemical industry

PVC stabilization continues to migrate from legacy heavy-metal systems to calcium–zinc and organic solutions. This shift is driven by global regulatory frameworks, brand-owner requirements, and circular-economy targets. Within this context, 6642 31 5 supports heavy-metal-free formulations and contributes to recyclability by mitigating thermal degradation during both first processing and reprocessing cycles. As markets demand higher recycled content and lower VOCs, choosing efficient co-stabilizers becomes a strategic lever for compliance and performance.

HEBEI GUANGXING CHEMICAL INDUSTRY CO., LTD. positions CAS No. 6642-31-5 within a forward-looking portfolio. The company emphasizes consistent quality, tight impurity control, and supply reliability to help customers meet RoHS- and REACH-conscious market expectations (application-specific assessments recommended). By aligning technical support with sustainability goals—such as longer tool life, fewer rejects, and stable processing at lower temperatures—HEBEI GUANGXING enables B2B decision makers to scale greener formulations without sacrificing throughput or product performance.
