Performance & Applications

1. SP is soluble in ethanol, acetone, benzene, and hydrocarbon solvents.

2. SP is a non-polluting antioxidant used in natural and synthetic rubber products. It does not extract and has good dispersibility. Suitable for white and light-colored products. Mainly prevents thermal aging and cracking due to flexing. Dosage: 0.5~3%.

3. Used as antioxidant for polyolefins and polyformaldehyde; polyolefin addition is 0.01~0.5%.

4. SP can also be used as a stabilizer for styrene-butadiene, isoprene, ethylene propylene, and other synthetic rubbers, with a dosage of 0.01~0.5%.

5. Used as an intermediate for chemical synthesis.
