Ultraviolet absorber UV-P is a UV absorber for 290-400nm, which has good photostability effect – converts ultraviolet rays into heat energy through photochemical action . It is a light yellow powder or crystal with good light stabilization effect – it converts ultraviolet rays into heat energy through photochemical action. Soluble in a variety of organic solvents such as gasoline, benzene, acetone, etc., and has very little solubility in water. Can be dissolved in alkali to form yellow salt.
The uses of ultraviolet absorber UV-P are as follows:
According to the supply of ultraviolet absorbers: UV absorber UV-P is effective for most polymers UV protection can be provided for polyvinyl chloride, polystyrene, polyester and acrylic resins, vinyl and vinyl/acrylic polymers, polyurethane, polycarbonate and fiber esters.
UV absorber UV-P has good thermal stability and can be used for high-temperature processing of plastics such as polycarbonate under normal processing conditions.
Ultraviolet absorber UV-P hardly absorbs visible light, and is especially suitable for colorless, transparent and colored products
In outdoor products, it can be combined with phenolic antioxidants and phosphites used together with antioxidants.
General dosage: 0.1-0.5% for thin products and 0.05-0.2% for thick products.
