Oxidized polyethylene wax

Oxidized polyethylene wax (CAS 68441-17-8), commonly referred to as OPE Wax, is produced by controlled oxidation of polyethylene to introduce polar functional groups.

Where is Oxidized polyethylene wax used?

• Plastics processing, coatings and printing: lubricant, surface modifier and rheology agent
• PVC and thermoplastic compounding: external lubricant and processing aid
• Coatings and polishes: surface slip, scratch resistance and matting effect
• Printing inks: control of rub resistance and gloss on flexible packaging substrates
• Rubber and tire manufacturing: mold release and dispersing agent for carbon black and other fillers
• It reduces die buildup and improves mold release without compromising mechanical properties.

Good to know: These polar groups improve compatibility with polar substrates and dispersibility in aqueous systems. Standard grades are differentiated by acid value, melt point, and viscosity.

Commercial specifications

• Emulsifiable grades for water-based coating and polish applications
• Specifications typically align to customer-defined acid value ranges and melt point windows
