Styrenated phenol is a stabilizer for synthetic rubbers and natural rubbers such as styrene-butadiene, chloroprene, and ethylene-propylene. It has excellent anti-aging effects in rubber and latex products. It can improve the heat and oxygen aging resistance of products. It is non-toxic and pollution-free. The dosage is generally 2.0-5.0. In the plastic industry, it is used as an antioxidant for polyalkanes and polyformaldehyde, and the dosage is generally 0.5-2.0.
