Yiphos™ 3019

Distearyl pentaerythritol diphosphite. Acts as an antioxidant. Is highly effective color and molecular weight stabilizer for polyolefins, polyesters, elastomers, styrenics and engineering thermoplastics. Also contributes to the thermal and UV stability of these polymers. Provides very good color stability during processing, fabrication and end use. Exhibits polymer protection from degradation during processing. Reduces discoloration of polymers containing pigments such as TiO2 and polymers that are stabilized with a sulfur-containing, nickel-organic complex and are processed at high temperatures. Shows synergism when used with light stabilizers such as benzophenones and benzotriazoles. Offers high performance at low loading levels for most cost effective formulations.
