Applications

UV831A is a three components of structure-stable UV light stabilizer and UV-light absorber,  It exhibited a bit better performance in both thermal aging, UV light aging and anti-yellowing properties compared to Cytec light stabilizer 3808 and v703. Therefore it can be used as an excellent light protection for polymer materials such as PP, PE, ABS, EVA, PS, TPO, PU, PA and so on.
