Different from the other antioxidants, it can't be absorbed by creatural tissues after oral taking, and entirely vent from dejection. Approved by FDA, it is suitable for rubber produce and plastic apparatus which are used in food and medical health field, widely used as antioxidant and heat stabilizer in high or low pressure ployethylene, polypropylene, polystyrene, polyformaldehyde, chlorinated polyether, polyamide, natural or synthetic rubber, adhesive and lubricating oil with high melting point. It can improve aging resistance, high temperature resistance, withstanding pressure, abrasion resistance, oxidation resistance of the product to keep good luster and prolong lifetime. It can be applied to package of food to keep good luster of plastic. Used in cable material, because of its low dielectric loss, the performance is obviously better than old antioxidants such as 1010.
