About HUAJIN Release the
Potential of Polymers

Huajin New Materials (Zhejiang) Co., Ltd. is a technology-driven manufacturer specializing in polymer lubrication and processing additives.

Oxidized polyethylene wax is one of our core product lines and technical strengths, supported by independently developed gas-solid phase oxidation technology. Together with our broader range of waxes and functional lubricants, it enables us to provide balanced lubrication solutions for different polymer formulations and processing conditions.

Our products are widely used in rigid PVC and CPVC applications, including foam board, WPC, SPC and other extruded products. In flexible PVC processing, they serve applications such as calendered films and heat-shrink films. They are also used in transparent PVC products, including transparent tubing and other applications requiring good clarity, compatibility and processing stability.

Beyond PVC, our additives are applied in masterbatch, engineering plastics, coatings, hot-melt adhesives and other polymer systems. By combining reliable products with application-oriented technical support, Huajin helps customers optimize fusion behavior, lubrication balance, dispersion, release performance, processing stability and overall product performance and quality.

Technology From Material Structure to Processing Performance.

Polymer lubricant performance is governed by molecular features and matrix compatibility. For oxidized polyethylene wax, oxidation degree and polar‑group distribution are also critical.

Huajin uses material characterization and application testing to evaluate additive impacts on key processing indicators and product performance. Correlating lab data with real‑world production results, we offer tailored additive solutions for rigid/CPVC, flexible, transparent PVC and other polymer systems.
Manufacturing Built for Consistency.
Ready for Scale.

Consistent product quality relies on standardized, repeatable manufacturing. Huajin implements full‑process control covering raw material inspection, batching, production, finishing, packaging and product release.

SOPs, process records, batch traceability and final inspection ensure stable lot‑to‑lot quality; each batch passes quality assessment prior to delivery. With mature oxidized polyethylene wax production and diverse wax & functional lubricant lines, Huajin delivers reliable supply, flexible options and prompt service.
