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 703 is mainly used as ultra accelerator for natural and synthetic rubbers, and lattices. It is more active than ZDC in solid elastomer. The latex including this product can be used for a week without pre-vulcanization. It is excellent activator for thiazole accelerator. SG-R 703 is also antioxidant in rubber mixing. and It can improve aging resistance for vulcanized rubbers without discoloration, contamination, and gives excellent dispersion.

Nanjing Shuguang Chemical Group Antioxidant SG-R 601 has good anti-oxidation performance. It has both anti-oxidation as HALS has， and noncontamination as phenolic antioxidant has. It is widely used in natural or synthetic rubbers to replace antioxidants with contamination and toxicity. SG-R 601 is a highly effective, nontoxic, low cost rubber antioxidant, has excellent heat and oxidation resistance, can improve fatigue damage of crosslinked rubber under many cycles flexible distortion condition, and has good synergistic effect with antioxidant RD, 4010 to improve aging resistance and tear resistance, so it is used in manufacturing many kinds of rubber products such as tires, rubber hoses, rubber belts, rubber shoes and latex products. The common dosage is 1%-3%. It can also be applied to colored products of polyethylene, polyamide, polypropylene and cellulose. SG-R 601 also acts as stabilizer for various synthetic rubbers, the dosage is 0.5%~1.5%. In view of its poor anti-sunlight performance, it should be avoided to be used under sunlight.

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 330 is a kind of hindered phenol antioxidants with high efficiency, low toxicity, low volatility, and pollution free. Antioxidant 330 is white crystalline powder and stable at high temperature. It has low volatility, no pollution, no oral toxicity. Different from the other antioxidants, it can’t be absorbed by animals’ or human’s tissues after oral taking, and entirely vent from dejection. Approved by FDA, it is suitable for rubber products and plastic apparatus which are used in food, medical and health care areas. It is widely used as antioxidant and heat stabilizer in high or low density ployethylene, polypropylene, polystyrene, polyacetal, 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. It is also used in cable material, because of its low dielectric loss, the performance is obviously better than old antioxidants such as Irganox 1010.
