Oxidized Polyethylene Wax (OPE Wax) is polar‑modified low‑molecular‑weight polyethylene wax with carboxyl and hydroxyl groups on molecular chains. The introduced polar groups significantly improve resin compatibility. During PVC processing, it delivers balanced internal and external lubricating performance. In printing ink systems, it enhances rub‑resistance and surface slip of dried ink film. This multi‑functional industrial wax is widely used for plastic compounding and printing ink production

Product Detail

Product Overview Oxidized Polyethylene Wax (OPE Wax, CAS 68441‑17‑8) is obtained by controlled oxidation of low‑molecular polyethylene. Polar functional groups along the molecular backbone increase surface affinity towards polar polymer resins, pigments and fillers. For rigid PVC extrusion and calendering, it reduces melt friction, delays thermal decomposition and improves surface finish of finished profiles. When incorporated into solvent‑based and water‑based printing inks, fine wax particles migrate to the ink‑film surface during drying, forming a thin lubricating layer to boost abrasion and scratch resistance. It exhibits stable thermal performance under conventional industrial processing temperatures.

Key Features ‑ Polar modified polyethylene wax with improved compatibility for polar resin systems ‑ Balanced internal and external lubrication effect for rigid PVC processing ‑ Delivers remarkable abrasion‑resistant and slip‑improving properties for printing inks ‑ Good pigment wetting capacity, beneficial for color‑concentrated ink formulations ‑ Low volatility and favorable thermal stability during high‑temperature compounding

Typical Technical Properties ‑ Chemical Name: Oxidized Polyethylene Wax ‑ CAS No.: 68441‑17‑8 ‑ Appearance: Off‑white pellets or fine powder ‑ Melting Point: Refer to TDS ‑ Acid Value: Refer to TDS ‑ Melt Viscosity: Refer to TDS

Applications ‑ PVC processing: Internal‑external lubricant for rigid PVC pipe, profile and sheet production ‑ Printing ink: Anti‑abrasion slip additive for gravure, flexo and screen printing inks ‑ Color masterbatch: Dispersing agent for polar‑filled polyolefin masterbatch ‑ Industrial coating: Auxiliary slip and scratch‑resistant additive for solvent‑based coatings

Processing Recommendation For PVC compounding, add OPE wax during the hot kneading stage together with stabilizers and other processing aids. For ink production, incorporate wax powder at the grinding or high‑speed dispersion phase. Typical dosage ranges from 0.3‑4.2 wt% according to formulation requirements. Preliminary laboratory trials are strongly recommended before mass‑scale manufacturing.

Storage & Handling Store in cool, dry and well‑ventilated warehouse. Avoid direct sunlight and continuous high‑temperature storage. Reseal packages immediately after opening to prevent dust and moisture contamination. Wear proper gloves and dust‑proof mask when handling powdered wax.
