PVC plastic is a kind of commonly used plastic decoration materials, abbreviated as PVC materials, PVC molecular weight, softening point, crystalline weight will change with temperature, PVC plastic has the advantages of heat preservation, heat insulation, moisture-proof, flame retardant, light weight, convenient construction and so on. Due to the variety of specifications, colors and patterns, they are widely used in decoration, production and life, such as PVC water pipes, PVC plastic doors and windows, PVC plastic toys, wires and cables, etc. PVC resin is made from polyvinyl chloride resin as the main raw material, adding suitable anti aging agent and modifier, and so on.
 
PVC plastic is a hard material. It uses more fluorescent whitening agent and titanium dioxide. The single use of titanium dioxide can only make the product reach a certain degree of whiteness. It just plays a role of covering. At this time, it needs whitening agent to achieve the whitening effect. Shanghai enmai recommends a fluorescent whitening agent, It can make PVC plastic whitening effect is remarkable, and the maintenance time is 2-3 times of the usual whitening agent, it is the whitening agent KCB
 
It is light green or yellow powder, with bright blue and white light, fineness greater than 300 mesh, use temperature less than 250 ℃, non-toxic and tasteless, soluble in fat, petrolatum oil, paraffin and other organic solvents, weather resistance, heat resistance, oxidation resistance, whitening, brightening, brightening performance is good, has a strong fluorescence. It is widely used in plastic film, compression molding material and injection molding material, which can make the product white and bright. When using, evenly dissolve in the solvent or product, pay special attention to the situation that excessive addition will cause yellowing.
 
At present, many manufacturers of PVC plastic products in China use brighteners from distributors. Few manufacturers are looking for manufacturers because of a single additive. Shanghai enmai suggests that you should not underestimate this additive. It can achieve unexpected results in a small amount. Therefore, we recommend the use of fluorescent brightener KCB, which is an indispensable additive for PVC plastic.,
