It is antioxygen, which can be used in synthetic rubber, polyolefin plastic, and other high polymer materials, lubricant, fuel oil and other oils.

The preparation is compounded by phenolic antioxygen and other accessory antioxidants.

New-model SPJ-DKY antioxidant is compound preparation of phenolic antioxygen and auxiliary antioxygen. The system has favorable synergistic effect. The product is liquid antioxygen. Compared with traditional antioxidants 1076 and 2246, TNPP, it has longer oxidation induction time, better thermal and oxidative aging resistance, lower Mooney viscosity change, low gel production rate. The product is non-toxic, environment-friendly and high efficient antioxygen.
