Physical Form & properties

*White powder

UV838 is astructure-stable  hindered Amine UV Light Stabilizer

* It's suitable for light and dark color polymer materials

*Melting Point: 51-75℃   TGA: 361.35℃ (50%)

* It can replace 3853 light stabilizer.

Applications

UV838 is a structure-stable hindered amine as UV light stabilizer, it's melting point is high enough for four season storage and conveniently usage. It exhibited higher performance in both thermal aging and UV light aging compared to Cytec light stabilizer 3853. Therefore it can be used as an excellent light stabilizer in PP, PE, ABS, EVA, PS, TPO, and so on.
