Performance：

ER fluorescent whitening agent, also known as polyester whitening agent, is a bidystyrene compound, the appearance of yellow-green powder crystallization. Non-toxic, odorless, purity ≥99%, melting point 229-231 degrees C, non-ionic, can be soluble in most organic solvents,  similar as  Blankophor ER,which from Bayer, Germany.  With excellent heat resistance and light fastness aslo. 

Purpose：

ER fluorescent whitening agent powder, very suitable for polyester (polyester) fiber whitening, brightening, polyethylene, polypropylene, PVC and other plastics and products, but also has a good whitening effect. In the polyester slice and recycling polyester slice molding process to add ER fluorescent whitening agent concentrate powder, can significantly improve the product grade. It is also widely used in the coatings industry.

Usage：

The ER fluorescent whitening agent powder and polyester slices and other additives together into the mixing machine, the recommended dosage is 0.02-0.08% (with polyester weight ratio), the specific amount can be based on the whiteness requirements of the finished product. Mix well and evenly at 50-150°C and draw at 240-300°C.

③Melting point: ≥ 295 °C.
④Solubility: insoluble in water, soluble in high boiling point organic solvents such as trichlorinated benzene.

Purpose：

Fluorescent whitening agent KSN and OB-1 have a similar chemical structure, but the whitening effect of polyester and plastic products is better than OB-1, and the solubility with plastic is better than OB-1, very little dosage can produce a very good whitening effect, which is far from OB-1. KSN is not only high temperature resistant, but also excellent sun and climate resistance. Fluorescent whitening agent KSN is also suitable for the whitening of polymer fibers such as polyamide and polypropylene, and can also be used in films, injection molding and extrusion molding materials, where the addition of KSN to any processing stage of synthetic polymers has a good whitening effect.

Usage：

The fluorescent whitening agent KSN is 0.01-0.05% equivalent to the weight of plastic or polyester particles, and is fully mixed with the material before various plastic molding processes or polyester wired.

②Melting point: 357-359°C.
③Solubility: insoluble in water, soluble in high boiling point organic solvents such as trichlorinated benzene.
④Chemical Structure : Is a distyrene bistyrene whitening agent.
⑤Other characteristics: Because of the high melting point of the whitening agent, it has good heat and light resistance, and chlorine drift resistance is particularly good.

Purpose：

The whitening agent is particularly suitable for molding and processing of various plastics and plastic products at high temperatures, because of its good heat, light and chlorine drift properties, so the whitening of polyester fibers and polyester and cotton and other fiber blend textiles whitening effect is also particularly ideal, and can be used as polyester original whitening, similar as : Whitex SNK, Uvitex ERT, Eastobrite OB-1.

Usage：

The whitening agent is 0.01-0.05% of the plastic or polyester particles, before the molding of various plastic products or polyester fiber extraction, with the material fully mixed evenly.
