Oxidized Polyethylene Wax (OPE) CAS 68441‑17‑8 is functional polyethylene wax manufactured by controlled oxidation of low‑molecular‑weight polyethylene. Carboxyl and hydroxyl polar groups are introduced onto the hydrocarbon molecular chain. Compared with conventional non‑polar PE wax, OPE shows better compatibility with polar polymer resins and inorganic fillers. It provides combined internal‑external lubricating and releasing functions. Inside the polymer matrix, internal lubrication decreases

Product Detail

Product Detail Page: Oxidized Polyethylene Wax (OPE) is produced via controlled thermal‑oxidation reaction of low‑molecular‑weight polyethylene. The molten crude material passes through filtration, refining, cooling and solidification, then processed into flakes, granules or fine powder. Each production batch is strictly tested for softening point, acid value, melt viscosity, ash content and lubricating‑dispersion performance, to guarantee stable processing properties for polyolefin and polyester extrusion compounding.

Extrusion production of PE, PP, PS, ABS and polyester materials faces typical processing difficulties. Non‑polar ordinary PE wax exhibits poor wetting capacity towards inorganic fillers and polar resin systems. Insufficient internal lubrication causes high melt viscosity and sharply rising extruder torque. Without proper external lubrication, molten polymer adheres continuously to screw surfaces and die lips. Degraded resin residues gradually build stubborn plate‑out deposits. These deposits generate surface streaks, dark spots and gloss defects on extruded profiles, sheets and pellets, forcing frequent machine shutdown for die cleaning. In masterbatch and filled modified compounding, poor pigment‑filler wetting leads to particle agglomeration, speckles and uneven color distribution on finished plastic products.

When uniformly blended into plastic formulations at the recommended dosage, OPE wax melts under processing heat. The polar segments of OPE molecules improve wetting towards pigment and inorganic filler particles, helping break up filler agglomerates and promoting homogeneous dispersion inside resin matrix. The internal‑lubricating fraction reduces intermolecular friction within molten polymer, lowering shear resistance and stabilizing extrusion torque during continuous running. A portion of OPE wax gradually migrates to the contact boundary between hot polymer melt and metallic equipment surfaces, forming a continuous low‑friction slippery boundary film. This boundary layer effectively reduces resin‑metal adhesion, suppresses plate‑out buildup on die lips and extruder components, facilitates auxiliary mold‑release for occasional injection‑molding operations, and improves surface gloss of extruded PE, PP, PS, ABS and polyester finished articles.

Precise dosage control is essential for formulation development. Under‑dosage results in insufficient lubrication, poor filler dispersion, high extrusion torque and severe plate‑out defects. Excessive addition will weaken mechanical properties of finished plastic goods and may trigger surface blooming. Preliminary laboratory compounding and extrusion trials are strongly recommended before mass‑scale manufacturing. OPE wax can be used synergistically with antioxidants, thermal stabilizers and mineral fillers for polyolefin, ABS and polyester modification systems.

For compounding operations, flaked, granular or powdered OPE wax is added during high‑speed premixing with base resin, pigment and fillers prior to twin‑screw extrusion pelletizing or direct profile‑sheet extrusion.

Store the sealed product away from moisture and foreign contaminants. Long‑term high‑temperature storage may cause softening and partial caking of wax particles.

Major application fields: lubricating and release processing wax for PE, PP extrusion and filled polyolefin modification; anti‑plate‑out auxiliary additive for PS and ABS extrusion compounding; pigment‑filler dispersing and releasing aid for polyester extrusion and modified engineering‑plastic compounding.

Store the product in tightly‑sealed original bags within 15‑30℃, maintain dry storage and avoid direct sunlight.
