uv absorber & light stabilizer & antioxidant

We are the professional supplier of uv absorber & light stabilizer & antioxidant, main like LS 519 CAS 42774-15-2 / Nylostab S-EED Powder; and Photoinitiator TPO-L, etc…

For Nylostab SEED Powder/ LS 5519 acts as a tabilizer of melt or as a melt process modifier, due to its unique molecular structure. This effect is manifested by high stabilizer of polyamide melt pressure which leads to higher quality of injection and blow-molded or extruded PA articles, as well as lower rate of filament breaks during fiber spinning. It is characterized by: -Multi-functional additive for polyamides -Improved melt processing of polyamides -Enhanced long-term heat and photo-stability -Enhanced dye ability, Easy handling -Superb compatibility with polymers

For Light initiator (photoinitiator), also known as photosensitizer (photosensitizer) or light curing agent (photocuring agent), is a kind of chemical compounds which can absorb certain wavelengths of energy, produce free radical and cationic in the uv region (250 ~ 420 nm) or visible light area (400 ~ 800 nm) to initiation of monomer polymerization crosslinking curing.

TPO-L is an efficient free radical type I liquid photoinitiator, which is mainly used for UV curing of corresponding resins. It is especially suitable for curing of low yellowing, white system and thick film. Silk Printing Ink, Lithographic Printing Ink, Flexible Printing Ink, Wood Coatings.
