Optical Brightener KCB 367 CAS NO 5089-22-5 KCB dosage and usage:


The commonly used amount of optical brightener KCB is 0.01~0.03%. that is, the optical brightener KCB to add 10-30g for plastics is added to every 100kg of plastic raw materials, which can be adjusted according to different formulations and requirements for whiteness.


When adding any ultraviolet absorber to the polymer, pls adjust the dosage of optical brightener KCB,.


Because the amount of optical brightener KCB  added is small, the brightener should be dispersed thoroughly so that the brightener can be evenly dispersed in the entire polymer. If a brightener is used as the optical brightener masterbatch, it is easier to achieve a sufficient dispersion effect.

Optical Brightener KCB 367 CAS NO 5089-22-5 KCB Price Trend:


Although the total demand for optical brightener KCB is not very large, but it is very important for foam EVA. In the past two years, optical brightener KCB's raw material  has been in short supply, and the pressure on environmental protection has increased. Many optical brightener KCB manufacturers have stopped production. The stock of optical brightener  KCB on the market is limited, so the optical brightener KCB  price is rising.
