UV absorber is a widely used and well-known class of light stabilizers, according to its structure can be divided into Salicylate esters, Benzophenone, Benzotriazole, Triazines, etc., And quenching agent is mainly some bivalent organic nickel chelate, its organic part is substituted phenol and thiobisphenol.
Quencher can quickly and effectively quench the excited state molecules (single-linear state oxygen and three-linear state substances) through the intermolecular energy transfer, so that the conversion into heat or into fluorescence, and radiation dissipation, then back to the base state. Through this process, organic nickel quencher protect polymers from UV damage, so as to achieve the purpose of stabilizing the polymer materials. It is different from UV absorbers (which do not strongly absorb UV rays), and it is usually used in combination with UV absorbers, showing good synergistic effect.
OMNISTAB UV1084 is such an organic nickel quencher widely used in agricultural films!
OMNISTAB UV1084 is widely used in polyethylene shed film, agricultural film. It has excellent resistance to pesticides and acid, and has a wide range of applications in the field of polypropylene, polyethylene fibers, artificial turf and so on.
UV1084 can also work well with other stabilizers, especially UV absorbers, in polyolefin products with strong compatibility, in PE agricultural film and PP turf and other products with high stability, resistance to pesticides and acidic erosion. It is also suitable for PE and PP films, tapes and other products.
Besides UV1084, we also supply following UV absorbers and long-acting light stabilizers for agricultural films:
OMNISTAB UV3529 has dual functions of hindered amine group and triazine group. It has high temperature resistance, extraction resistance, low weight loss and good light stabilization efficiency. UV3529 is a long-lasting light stabilizer for polyolefin composites and films.
OMNISTAB LS783 is a synergistic mixture of LS944 and LS622. It's widely used in LDPE, LLDPE, HDPE films and package applications.
OMNISTAB LS119 is a kind of high molecular weight HALS widely used in PE and PVC ariculture films. It is worth mentioning that it's a low alkaline HALS so it is resistant to acids, alkalis and other extreme conditions.
