2-hydroxy-4-(octyloxy)benzophenone; BP12; Octabenzone
Yes
Non-hazardous
10 MT for net 25 kg carton
Specification
Item | Specification |
Appearance | light yellow crystalline powder or flakes |
Purity | 99.0% min |
Melting point | 47.0 - 49.0 °C min |
Loss on drying | 0.5% max |
Residue on ignition | 0.1% max |
Transmittance 450nm | 90.0% min |
Transmittance 500nm | 95.0% min |
Application
UV 531 is an ultraviolet absorber 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, polyurethane, acrylate and etc. Usage: 0.1%-0.5% based on polymers weight
Packing and Storage
Packing In 20 or 25kgs net carton
Storage Keep tightly closed and store in cool and dry place
Safety Information
Non-hazardous for air, sea and road freight
