Application:
2-Hydroxy-4-n-Octyloxybenzophenone (Octabenzone; UV Absorber UV-531; Benzophenone-12) (CAS: 1843-05-6) is an ultraviolet light absorber (UVA) of the benzophenone class, imparting good light stability for plastics and other organic polymers. Due to its highly effective broad UV absorption properties and excellent polymer compatibility, UV- 531 offers maximum polymer protection and low color contribution, retards yellowing and loss of physical properties. UV531 is a highly efficient ultraviolet absorber with low volatility, resistance to migration and easy processing properties. It has excellent synergistic effect with antioxidant and light stabilizer. UV Absorber UV-531 is a light stabilizer with good performance, capable of absorbing the UV radiation of 240-340 nm wavelength with the characteristics of light color, nontoxic , good compatibility, small mobility, easy processing etc. It can protect the polymer to its maximum extent, helps to reduce the color. It can also delay the yellowing and obstacle the loss of its physical function. It is widely applied to PE,PVC,PP,PS,PC organic glass, polypropylene fiber, ethylene-vinyl acetate etc. Moreover, it has very good light-stability effect on drying phenol aldehyde, varnish of alcohol and acname, polyurethane, acrylate, expoxnamee etc.. The recommended dosage is 0.1%--0.5%. UV Absorber UV-531 acts as a UV absorber ,finds application in formulating color cosmetics and hair-, sun- and body care products. Its dosage is 0.1%-0.5%. 1. Polypropylene : 0.2-0.5wt% based on polymer weight 2. PVC: Rigid PVC : 0.5wt% based on polymer weight. Plasticized PVC : 0.5-2 wt% based on polymer weight.Sufficient Capacity: Sufficient facilities and technicians
OEM Package: Custom package and label available
