How To Deal With The Oxidation Reaction Of Material Pe Uhmw ?
The method of changing the oxidation reaction of the material pe uhmw is to add a reagent having an anti-ultraviolet function and an antioxidant, such as an ultraviolet absorber or carbon black, to significantly improve the aging resistance.
Material pe uhmw is odorless, non-toxic, waxy, and has excellent low temperature resistance. It is a kind of high-crystallinity, non-polar thermoplastic resin, but it will age and discolor under the action of ultraviolet rays in the atmosphere and sunlight. Cracked, brittle or powdered, losing its mechanical properties.
At the molding processing temperature, the viscosity of the melt is also lowered due to oxidation, discoloration occurs, and streaks appear, so care should be taken during molding, use, or material selection.
