This product is one of the few non-toxic, odorless, and light colored antioxidant varieties among amine antioxidants. Widely used in various elastomers. Applied to plastic masterbatch such as polyethylene, polypropylene, and polyvinyl chloride. It can be used as an antioxidant for polyurethane foam plastics, rubber wires, cables, food packaging materials and adhesives, especially in neoprene colored cable sheaths, the antioxidant KY-405 has remarkable heat resistance, light resistance and aging resistance. It can be used as light resistant and anti-aging antioxidant in polyether and its foam plastics, and also as lubricating oil antioxidant. Especially effective in protecting against aging caused by high heat, light, etc. in chloroprene rubber, acrylic rubber, polyether polyols, etc. It has a good synergistic effect with sulfur-containing antioxidants and a good synergistic effect with phenolic and phosphite antioxidants

Antioxidant KY-616

Mainly used to protect light colored and stain free compounds, such as natural rubber, sealants, ABS, BR, IR, NBR, NR, SBR, SBS, SIS and other derivatives. It can be used in the processing of polymers, such as elastic silk thread, carpet backing, foam rubber pad materials, shoe sole materials, household and surgical rubber gloves, medical products, baby pacifiers, rubber additives, thermos bottles, bathroom mats, auto parts, paper coatings, etc., to enhance stability. It can protect natural and synthetic polymers based on isoprene and butadiene chemistry, and can serve as an efficient tire (butyl) anti-aging agent. The antioxidant effect is superior to that of monophenols and bisphenol antioxidants.
