(4)Application: optical brightener OB*1 is a highly efficient optical brightener used for lanon and widely applied to ABS,PS,HIPS,PA,PC,EVA and hard PVC etc. its features include admirable whitening effect,excellent thermal stability and very fewer usage amounts.
(5)Usage Amount: the dosage of optical brightener OB*1 should be added to per **0kg of polymer( just for reference)
Transparent: dosage0.*****0.**5%(2.5g*5g)
General Dosage:0.*****0.**5%(2.5g**5g) no more than 0.*3%(*0g)
When you append any ultraviolet absorbents,take care of adjusting the optimum dosage of your optical brightener.
(6)Usage:Because the little addition of optical brightener, you should separate the brightener drastically,ensure it will be homogeneous distributed in the whole polymer.if you use the concentrated grain,it can be easier to achieve the sufficient dispersion effect.
(7)Attention:When the optical brightener was applied to PE and soft PVC,you should take cake of the dosage control. the overfull dosage may cause brightener transport phenomenon.
