Polyvinyl chloride (PVC) is a kind of polymer polymerized by vinyl chloride monomer (VCM) in peroxide, azo compounds and other initiators or under the action of light and heat according to the mechanism of free radical polymerization. PVC used to be the most widely used plastic in the world. It is widely used in building materials, industrial products, daily necessities, floor leather, floor tiles, artificial leather, pipes, wires and cables, packaging films, bottles, foaming materials, sealing materials, fibers, etc.
Optical brighteners, also called optical brightener agent or fluorescent whitening agent, is a kind of fluorescent dye, or white dye, and it is a complex organic compound. It can absorb the invisible ultraviolet light and convert into the longer wavelength blue light, which superposed with the yellow light emitted by the plastic raw material itself, than give the white light after the complementation. So that the white light emitted by the plastic increases. The naked eye can feel that the white plastic becomes brighter and whiter obviously. Optical brightener has a group of products suit for different end using such as fiber, fabric, plastics, detergent, paint & coating, ink and so on.
Optical brightener 393 (OB-1) is kind of optical brightener for PVC (Polyvinyl chloride). It’s also suitable for various of polymers. In the family of optical brighteners for plastic, it’s especially good optical brightener for rigid PVC. The application of optical brightener OB-1 for PVC contains vast of products like PVC pipes and tanks (gutters, drinking water pipes, air duct, casing and so on), PVC profile (window frame), PVC decoration materials (buckle plate, floor & wall, garden fence and so on), PVC film and foamed PVC products, just named a few. Except the PVC products, it’s also an optical brightener for PVC master-batch.
