About Grand Chemical
Grand Chemical is a manufacturer and exporter of optical brighteners based in Jinan, Shandong. The product line runs from the benzoxazole grades that plastics compounders buy by C.I. number, through the stilbene grades that cotton and paper mills use, to the distyryl-biphenyl grades the detergent industry specifies - plus the pigments, heat stabilisers, impact modifiers and nucleating agents that tend to travel on the same order.
We make and export optical brighteners for plastics, rubber, textiles, detergents, coatings and inks, and supply the polymer additives and pigments that go on the same orders.
