 KY-405 for plastics is a highly effective non-discoloring aromatic amine type antioxidant finding utility as a thermal stabilizer in a wide variety of applications, including polyolefins, styrenics, polyols, hot melt adhesives, lubricants and polyamines.

Excellent performance at processing temperatures, strong synergy with other types of antioxidants, such as phenolics or phosphites, makes KY-405 for plastics an excellent choice as a component of a thermal stabilizer package.

KY-405 is a white powder that is relatively nondiscoloring during heat aging.

The combination of high amine antioxidant activity and good color make it an ideal antioxidant and heat stabilizer for rubbers and plastics. Especially effective in EPDM, Neoprene, nitrile (e.g. Paracril).

Hydrogenated nitrile and ethylene-acrylic rubber. As an amine antioxidant, it is susceptible to UV discoloration.

Antioxidant effect is similar to Uniroyal (US) Naugard445, Ouchi (Japan) Nocrac CD, BASF antioxidant L5
