Traditional paraffin wax has obvious shortcomings such as single function, poor compatibility and low heat resistance, which easily cause uneven plasticization, mold residue, yellowing, blooming and precipitation in PVC production. With a unique polar molecular structure, OPE wax provides balanced internal and external lubrication, suitable for high-filled, transparent, rigid and soft PVC systems. It optimizes production conditions, improves product gloss and mechanical properties, reduces defective rates, and serves as an ideal substitute for traditional paraffin wax to upgrade formulas and cut costs.
