How To Deal With The Oxidation Reaction Of Polyethylene Sheet?

  The way to change the oxidation reaction of polyethylene sheet is to add reagents and antioxidants with anti-ultraviolet function, such as ultraviolet absorber or carbon black can significantly improve its resistance to aging changes.

    PE sheet is odourless, non-toxic, feels like wax, has excellent low-temperature resistance, is a kind of thermoplastic resin with high crystallinity, but under the action of ultraviolet rays in the atmosphere and sunlight, it will be aged, discoloured, cracked, brittle or chalked, and lose its mechanical properties.

    In the moulding processing temperature, also due to oxidation, so that its melt viscosity decreases, discolouration, streaks, so in the moulding process and the use of the process or selection of materials should be paid attention to.
