Applications

YIPHOS® 2020 is not only an excellent catalyst for esterification, but also provides superior color protection performance in the polymer synthesis process.YIPHOS® 2020 is a phosphite processing stabilizer, it can b e wi-dely applied as a non-stain & non-discoloration stabilizer and ant-ioxidant due to its more rapid decomposition capacity of peroxide. With excellent processing
heat stabilization in elast-omers, adhesives, engineering plastics, synthetic resins, miner -al oil and other organic matrix,it can improve the color and brightness of the products.YIPHOS® 2020 also can improve the plateoutperformance of the PVC products.
