Applications
YIPHOS® 2050 is mainly used as chelating agent for PVC. It can inhibit the color change and increase the oxidation resistance & light stability. It can improve the color and weatherability when working with the metal soap in PVC processing. In polyolefin, polystyrene and polyamide, YIPHOS® 2050 can be used as a secondary stabilizer. Furthermore, it has lgnition resistance and color stability in the polyurethane foam.
