EVA Copolymer Wax is low‑molecular‑weight ethylene‑vinyl‑acetate copolymer, formulated as a direct replacement for A‑C 400A. The introduction of vinyl acetate polar segments brings balanced polarity and flexibility. This product improves interfacial compatibility between different polymer phases, enhances wetting for fillers and pigments. It is a versatile functional additive for hot‑melt adhesives, surface coatings and various plastic modification applications.

Product Detail

Product Overview EVA Copolymer Wax (CAS 24937‑78‑8) is a modified polyolefin wax serving as alternative to A‑C 400A. With flexible vinyl‑acetate groups distributed on the molecular backbone, the wax obtains moderate polarity, which bridges non‑polar polyolefin and more polar polymers, fillers or tackifier resins. It exhibits stable melting behavior and relatively low melt viscosity during thermal processing.

Key Features ‑ Excellent polymer compatibility, improves miscibility of blended plastic systems ‑ Good wetting performance for pigments and mineral fillers ‑ Moderate flexibility, reduces brittleness of hot‑melt adhesive formulations ‑ Fair thermal stability with low fume under standard processing temperatures ‑ Reliable drop‑in replacement of A‑C 400A to lower formulation costs

Typical Technical Properties ‑ Chemical Name: Ethylene‑Vinyl‑Acetate Copolymer Wax ‑ CAS No.: 24937‑78‑8 ‑ Appearance: Off‑white pellets ‑ Melting Point: Refer to official TDS ‑ Melt Viscosity: Refer to official TDS ‑ Vinyl Acetate Content: Refer to official TDS

Applications ‑ Hot melt adhesive: Improve flexibility, adjust open time and enhance tackifying effect ‑ Plastic modification: Compatibilizer for polyolefin blends and filled compounds ‑ Industrial coating: Improve leveling and substrate wetting property ‑ Color masterbatch: Assist pigment dispersion inside polyolefin carrier resins

Processing Recommendation Incorporate EVA copolymer wax at the melt‑mixing stage during extrusion or kneading. Typical addition dosage falls within 1‑6 wt% depending on individual formulation. Preliminary lab trials are highly recommended before large‑scale manufacturing.

Storage & Handling Keep stored inside cool, dry, ventilated warehouse. Protect products from direct sunlight and excessive heat. Reseal opened sacks to prevent moisture absorption. Follow standard personal protection guidelines for industrial chemical operation.
