6642 31 5 Overview

CAS No. 6642-31-5 is widely referenced in the plastic heat stabilization toolbox, particularly in modern calcium–zinc (Ca–Zn) systems for PVC and other halogen-containing polymers. As a performance component in heat stabilizer packages, 6642 31 5 contributes to maintaining initial color, slowing dehydrochlorination, and extending long-term thermal stability under demanding processing and service conditions. In B2B terms, it supports consistent extrusion and molding windows, reduces scrap risk, and protects polymer properties across a wide range of temperatures. For buyers searching by identifier, “cas no 6642 31 5” ensures easy cross-referencing in technical documentation and regulatory databases.

From a technical standpoint, 6642 31 5 is chosen for its synergy in Ca–Zn stabilizer packages, compatibility with co-stabilizers (such as epoxidized oils) and lubricants, and its low volatility profile that supports reduced plate-out and clean processing. Typical usage is optimized through lab screening and plant trials—often in the range common to Ca–Zn packages—balancing initial color with long-term heat stability. HEBEI GUANGXING CHEMICAL INDUSTRY CO., LTD. supplies this material within carefully engineered systems, backed by rigorous quality control, reliable lead times, and technical service tailored to PVC processors and compounders.

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

Across rigid and flexible PVC, 6642 31 5 helps stabilize thermal profiles during extrusion and calendaring, making it suitable for profiles, pipes, siding, wire & cable insulation, transparent films, and injection-molded parts. In wire & cable, it supports color hold and insulation integrity at elevated processing temperatures. In rigid profiles and pipes, it helps minimize discoloration, aids long-term heat aging performance, and maintains mechanical strength. Because it integrates well with Ca–Zn systems, it is a pragmatic choice in applications moving away from legacy heavy-metal stabilizers while preserving production efficiency.

• Competitive advantages include strong initial color control, low odor/low volatility behavior for clean tooling, and robust synergy with common co-stabilizers and lubricants.
• Broad compatibility across compounding platforms enables simplified inventories and easier formulation adjustments to meet regional requirements.
• HEBEI GUANGXING CHEMICAL INDUSTRY CO., LTD. leverages application know-how to recommend dosages and blends that balance heat stability, transparency (where needed), and cost-in-use.

Cost, Maintenance & User Experience

Total cost of ownership for heat stabilizers is driven by more than price-per-kilo. With 6642 31 5, processors typically see savings through reduced plate-out, fewer color corrections, and more stable cycle times—factors that directly lower scrap and unplanned downtime. The product’s clean-processing profile supports longer intervals between die and screw cleaning, translating into higher asset utilization. In a competitive environment, these operational efficiencies can outweigh marginal differences in unit cost, boosting ROI across multi-line facilities.

Feedback from Polymer material additives customers indicates that consistent lot-to-lot quality is a key differentiator: predictable heat stability shortens formulation adjustments and accelerates plant trials. HEBEI GUANGXING CHEMICAL INDUSTRY CO., LTD. focuses on stable supply, technical troubleshooting, and tailored packaging options to simplify inbound handling and storage. Whether you are qualifying 6642 31 5 for a new PVC compound or optimizing an existing recipe, the user experience centers on reliability, throughput stability, and straightforward integration with current additive packages.

Sustainability & Market Trends in chemical industry

Market trends continue to favor lead-free, tin-free solutions, reinforcing the transition to Ca–Zn stabilizer technology in rigid and flexible PVC segments. Regulatory frameworks, such as RoHS and REACH, along with heightened OEM sustainability goals, are accelerating the adoption of low-VOC, low-odor stabilizer chemistries that maintain performance without compromising worker safety or environmental stewardship. Within this context, CAS No. 6642-31-5–based packages are valuable tools for meeting evolving compliance requirements while safeguarding product quality and brand reputation.

HEBEI GUANGXING CHEMICAL INDUSTRY CO., LTD. aligns with these directions by prioritizing eco-conscious formulation strategies, supporting recyclate incorporation, and offering technical guidance to reduce energy use during processing. Forward-thinking development pipelines, continuous product stewardship, and close collaboration with converters enable the company to deliver high-performing stabilizer systems that help customers meet environmental targets and anticipate future standards—without sacrificing processing efficiency or end-use durability.
