Qingdao East International Corp. wrapped up a successful run at CHINAPLAS 2026 in Shanghai, showcasing its full range of products including PE wax, oxidized wax, thermal crack wax, GMS, PTFE, and more. With 30+ years of expertise as a professional agent and manufacturer, the company delivers internationally certified quality to support the sustainable development of the plastics and rubber industry.

PVC Processing‌: The ‌acid value‌ of oxidized wax is the key parameter controlling the balance between internal and external lubrication. A ‌high acid value enhances polarity, promoting resin molecular chain slippage and significantly improving plasticization rate—ideal for highly filled, complex products like SPC flooring. A ‌low acid value is dominated by non-polar segments that enrich at the melt surface, strengthening mold release performance. For transparent products, ‌low-migration, FDA-compliant grades‌ must be selected to prevent blooming, haze, or safety risks. ‌Color & Filler Masterbatches‌: The ‌carbonyl and hydroxyl groups‌ in oxidized wax adsorb onto high-surface-area fillers such as carbon black, titanium dioxide, and calcium carbonate, reducing interfacial tension to achieve efficient wetting and dispersion, significantly lowering shear energy consumption. However, exceeding ‌8% loading‌ may saturate the polymer matrix, triggering a "reverse dispersion" effect. The critical threshold should be determined experimentally, and compatibility with the carrier resin’s polarity must be prioritized. ‌Coatings & Inks‌: ‌Micronized oxidized wax‌ migrates to the film surface during drying, forming a nano-scale protective layer that greatly enhances abrasion resistance, scratch protection, and anti-blocking properties. ‌Emulsified oxidized wax‌ disperses uniformly in water-based systems, improving leveling and tactile feel. Dispersion stability is crucial—micropowders require pre-grinding to prevent agglomeration, while emulsions must match the system’s pH and ionic strength to avoid coagulation or phase separation. ‌Leather & Textile Finishing‌: Oxidized wax emulsions form a film after application via spraying or padding, imparting ‌waxy, glossy, or matte finishes‌, while building a hydrophobic barrier to improve wear and stain resistance. ‌Non-ionic emulsions‌ are recommended for their broad compatibility and low reactivity with dyes or softeners. A ‌solid content of 30–40%‌ prevents sticky films and is ideal for high-friction applications such as shoe uppers and synthetic leather. ‌Hot Melt Adhesive Viscosity Modification‌: Oxidized wax acts as an efficient diluent, significantly reducing the melt viscosity of EVA, PO, or APAO-based systems, extending open time and improving sprayability. At ‌10–30% loading‌, compatibility with tackifying resins (e.g., rosin esters, C5/C9 terpene resins) must be carefully verified to prevent phase separation during high-temperature storage or loss of initial tack. ‌High-melting-point grades (>100°C)‌ are better suited for high-temperature application environments.
