Fluorescent whitening agent KCB is mainly used for whitening synthetic fibers and plastic products, and has a significant brightening effect on colored plastic products. It can be widely used in plastic films, laminating materials, and injection molding materials. For polyolefins PVC、 Foamed PVC, TPR, EVA, PU foam, synthetic rubber, etc. have good whitening effect.

Product Usage: Due to the small amount of fluorescent whitening agent added, it should be thoroughly dispersed to ensure that the whitening agent can be evenly dispersed throughout the entire polymer. If whitening agents are used to concentrate the masterbatch, it is easier to achieve sufficient dispersion effect. Fluorescent whitening agent KCB is an upgraded product of many fluorescent whitening agents, which has the characteristics of easy use, small dosage, and good effect.

Polyethylene: Polyvinyl chloride (PVC); Polystyrene; ABS; Polyethylene resin; In EVA foam products, the dosage is 0.03%, which means that the amount of plastic raw material input per 100KG is about 30g. Users can make appropriate adjustments according to product requirements.

Packing and storage can also be packaged according to customer requirements (25 kg × 1) cartons, paper drums, (1 kg × 1) bags. Can also be packaged according to customer requirements. Store in a dry place away from light.
