OPE wax for film processing

Oxidized polyethylene wax plays multiple critical roles in film processing.
The carbonyl and hydroxyl groups on its molecular chain confer exceptional
polarity, enabling it to form strong complex bonds with polar resins such as
PVC, thereby significantly enhancing lubrication performance. Functioning as
both an internal and external lubricant, it reduces friction between
materials and equipment to prevent roller adhesion while also diminishing
intermolecular friction, improving plasticisation efficiency and balancing
internal and external lubricity. Its low viscosity and high dispersibility
further promote uniform filler distribution, resulting in smoother, flatter
film surfaces with enhanced gloss and transparency. Concurrently, OPE wax's
high softening point and hardness strengthen the film's heat resistance and
structural integrity, preventing deformation at elevated temperatures.
Moreover, its non-toxicity and thermal stability facilitate widespread
application in sectors like food packaging, while its environmental
credentials align with industry trends. Overall, OPE wax effectively enhances
film processing efficiency and product quality through mechanisms including
lubrication, dispersion, and compatibility.
