Polymer Additives
UV-90 is a monomeric hindered amine light stabilizer (HALS). It functions by capturing free radicals and inhibiting photo-oxidation reactions, thereby protecting materials from damage caused by ultraviolet radiation.
[Molecular weight] 450
Appearance: White to off white crystalline powder
Melting point: 155°C - 158°C
Content: 99% min
Volatile: 0.8% max
Recommended for PA, PP, HDPE
1.UV-90 is beneficial for the extrusion of ABS, PA, and polyolefin products. 2.Particularly when used in chemical fibers, PET, and PP spinning, it ensures no crystal spots, no burrs, and no clogging of the spinneret.
3.In PE and HDPE, it significantly maintains the material's light resistance and environmental durability.
4.When applied in ABS, it greatly reduces product yellowing.
5.It shares the same amide functional groups as nylon, resulting in better compatibility
