UV326 is a UV absorber of 300-400nm, with good light stabilization effect, converting ultraviolet light into heat energy through photochemical action; the product has more effective absorption of long band, good compatibility with polyolefin, low volatilization and inhibiting phenol ionization; the product has good alkaline resistance and will not cause color change due to metals. Due to its high ionization constant, metal drying agent, catalyst on its low influence; in outdoor products, can be used with phenolic antioxidant and phosphite antioxidant.
It is mainly used in polyvinyl chloride, polystyrene, unsaturated resin, polycarbonate, polymetl methacrylate, polyetlene, ABS resin, epoxy resin and so on.
Recommended amount: 0.1% -1.0%, the specific amount is determined according to the customer application test
Packed in 20 or 25 Kg / carton.
