Nanjing Shuguang Chemical Group Antioxidant SG-R 3100 is a new type of p-phenylenediamine antioxidant, because the two aryl substituting groups are so large that it has low volatility, slow oxidation rate and long effective time. Used with the similar antioxidant like 4010A or 4020 it can make up for the antioxidant which is well efficient in early time but insufficient in the later time. At the same time, its anti metal-toxicity is better than 4010NA and 4020, and it is suitable for heavy loading tire, cross-country tire and car tire under harsh conditions.

Nanjing Shuguang Chemical Group Accelerant SG-R 705 is the rubber antioxidant. It is mainly used in such synthetic rubbers as SBR, NBR, chloroprene, chlorohydrin, chlorosulfonated polyethylene rubber and so on, and can prevent the cracking due to sunlight, ozone and enhance thermal stability for the chloroprene rubber and chlorosulfonated polyethylene. In plastic industry it serves as the UV stabilizer and the antiozonant of polymer material. It is used in polypropylene fiber, film and narrowband to provide good stability, but make the product appear yellow-green. The amount of dosage is 0.3 - 3 PHR.

Nanjing Shuguang Chemical Group Antioxidant SG-R 602 applies to nature rubber and synthetic rubbers such as SBR, NBR, chloroprene rubber, etc. with aging protection. It has protection from hot oxygen aging, flex fatigue and cracks. It can deactivate metals with various valences. SG-R 602 has remarkable heat anti-brittle function in chloroprene rubber, and strengthens the anti-ozone aging protection capability. It can reduce the Mooney viscosity of the chloroprene rubber, extend scorch time, enhance heat aging performance of the rubber material, increase the processing safety and the storage stability, so it is one of the most preferred antioxidants for chloroprene rubber.
