Fluorescent Brightening Agent OB for Plastic

Fluorescent Brightener OB is an effective and multifunctional additive for plastic materials. As a Pvc Optical Brightener, it is colorless, reflects visible light on plastic, and at the same time absorbs ultraviolet light in sunlight, emitting blue-violet (415-466nm) fluorescence, which complements the yellow light reflected by PVC and forms white light, which makes PVC have obvious whiteness and makes the whiteness of PVC more pleasing to the eye than ordinary bleaching or bluing. At the same time, this Fluorescent Brightener Agent has good thermal stability, which enables it to withstand the high temperature usually encountered in plastic processing. This ensures that the brightening effect remains unchanged even after the manufacturing process.

Recommended dosage: about 20g of OB whitening agent is added to every 100kg of material, and the specific dosage is adjusted according to the formula.

Packaging and storage: packed in cardboard barrels lined with plastic bags, with a net weight of 25kg/ barrel, or packed according to customers' needs and stored in a cool and dry place.
