YIPHOS^® 3019 is very suitable for the polymer application which requires high temperature process because of its properties of pentaerythritol structure and high molecular weight. It contains diphosphite structure and the content of alkyl trivalent phosphorus is higher, so the antioxidation effect is more outstanding and effective. YIPHOS® 3019 is produced through the phenol free process, no free phenolic residue and it is environmental friendly. Synergism when used with hindered phenol antioxidants.
YIPHOS^® 3019 can be used in ABS, PS, HIPS, NBR, SBS, PP, PE, LLDPE, PVC, PC, PA, PET, UP etc.
