Chemical Name:2-hydroxy-4-(octyloxy)benzophenone Synonyms:[2-Hydroxy-4-(octyloxy)phenyl]phenylmethanone Molecular Formula C21H26O3 Molecular Weight 326 Structure
CAS Number 1843-05-6
Specification Appearance:light yellow crystal powder Content:≥99% Melting point:47-49°C Loss on drying:≤ 0.5% Ash:≤ 0.1% Light transmittance:450nm≥90%; 500nm≥95%
Applications: This product 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
Dosage: 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
