the dose description
Add the amount of fluorescent whitening agent ob-1 per 100kg of polymer (reference amount)
Transparent: The amount added is 0.0025-0.005% (2.5g-5g)
The general dosage is: 0.0025-0.025% (2.5g-25g) Not more than 0.03% (30g)
When adding any UV absorber to the polymer, care should be taken to adjust the optimum amount of the optical brightener ob-1.
Since the amount of the fluorescent whitening agent added is small, the whitening agent should be thoroughly dispersed so that the whitening agent can be uniformly dispersed throughout the polymer. The whitening agent ob-1 may be uniformly mixed with the material before the molding process of various plastic products or before the spinning of the polyester fiber by 0.01-0.05% of the weight of the plastic or polyester pellets. If the brightener is used to concentrate the masterbatch, it is easier to achieve a sufficient dispersion effect.
