Oxidized polyethylene wax used as sealing material

The extensive application of oxidised polyethylene wax in sealing materials
is primarily attributable to its unique physicochemical properties:
High melting point and hardness: Oxidised polyethylene wax exhibits a melting
point exceeding 100°C, with certain grades reaching approximately 130°C.
This enables it to remain solid at elevated temperatures, delivering stable
sealing performance without softening or migration. Concurrently, its high
hardness endows the sealing material with excellent resistance to extrusion
and wear.
Strong Adhesion and Compatibility: Oxidation treatment introduces polar
groups into its molecular chains, significantly enhancing compatibility with
polar resins and other sealing material components. Simultaneously, it
exhibits strong adhesion to substrates such as metals, forming a robust
sealing layer.
