Molecular Weight: 4*0
CAS No.: ********5
C.I.: **4
Specifications:
Appearance: Yellowish or yellowish green crystal powder
Assay: *9% min.
Melting Point: ******3
Ash: 0.3% max.
Volatile Content: 0.3%max.

Max. Absorption Wavelength: **5nm(in ethanol)
Properties:
1. Optical Brightener Agent OB is highly effective in polymer substrates such as engineering plastics, e.g. PE, PC, PVC, PS, ABS, and PP, adhesive and other organic substrates.
2. Main applications include fibers, molded articles, films and sheets. And also can be used in clear lacquers, pigmented lacquers, paints, printing ink and synthetic leather. It will produce brilliant brightness with dyestuff, which is very efficient in directions for multicolor.
3. Optical Brightener Agent OB can be used as a tracer in a variety of applications.
4. OB features excellent resistance to heat, exceptional whitening properties, good light fastness and low volatility. It is readily soluble in organic solvents and features good compatibility in various substrates. The product is especially suitable for applications such as films and fiber.
OB enhances the whiteness of the substrate. In combination with dyes, the product produces particularly bright shades. Its excellent heat resistance renders OB suitable for all relevant
processing conditions. It is suitable for packing applications but local regulations must be observed.
Application (in each **0kg polymer):
PVC: White 0.***0.*5 (*0g**0g)
Transparent 0.*****0.**1% (0.1g*1g)
PS: White 0.**1% (1g)
Transparent 0.*****0.**1% (0.1g*1g)
ABS: Primitive color 0.***0.*5% (*0g**0g)
(effectively eliminate the intrinsic yellow color in ABS)
White 0.***0.*5% (*0g**0g)
PE, PP: Achromaticity 0.*****0.**1% (0.5g*1g)
White 0.****0.*5% (5g**0g)
Other Plastics: Refer to the directions given above.
When OB is used in PMMA polymerization, take care that the polymerization is conducted to full completion since interaction with residual monomer can cause discoloration in the final application.
Attention:
Please mix thoroughly to obtain best effect. OB concentrated master batch can be even better mixed.
Safety and Stock:
Keeping in stock as ordinary chemicals. Wear protective goggles and gloves while applying. Avoid direct contact with skin and eyes. Soap clean if skin contaminated.
