Applications
YIPHOS® 2140 has the characteristics of low volatility, good heat resistance and compatibility, and is suitable for various polymers, such as polyurethane, polyolefin, epoxy, coating and rubber materials. Due to its good heat resistance and high antiox-idant efficiency, when the addition amount is 50% of the traditional phosphite dosage, YIPHOS® 2140 can provide better anti-yellowing performance. This prod-uct is used in polyurethane materials to effectively improve the initial whiteness of polyurethane, provide excellent heat resistance and long-term stability for polyure-thane materials, and effectively inhibit the surface yellowing (phenolic yellow) caused by phenolic compounds. When its addition amount is 50% of anti-yellowing agent 130, 150, it can improve the anti-fading(NOx) effect. Recommended dosage is 0.1~1.0%
