RICHNOX 1010 is a processing and long-term thermal stabilizer system. It is a hindered phenolic type antioxidant.

RICHFOS 168 is a processing and long-term thermal stabilizer system. It is a solid phosphite type antioxidant.

RICHVIN 326 belongs to the family of substituted benzotriazole which protect against ultraviolet radiation. RICHVIN 326 has excellent stability to heat and is less likely to discolor with metal, make it particularly useful for stabilizing PVC, polyester coatings, and polyolefin.

RICHVIN 329 is a high molecular weight ultraviolet light absorber of the hy d roxyl Phenyl benzotriazole class. Its inherent off white color renders itself more suitab le fo r Application where light color is critical. Its low volatility and high lipophilicity makes it Especially useful where additive losses may occur during high temperature process.
