Is your A-388 Brightening agent same as Optical brightener ? NO

Many people might think our plastic brightening agent A-388 is Optical brightener like OB-1, OB, CBS-X, AV-1 ,FBAs ect. 

But it's totally wrong.  Belowed please kindly check the difference in details : 

1. Appearance : 

Optical Brightener : Green Powder

JINDAQUAN A-388 brightening agent: White Powder

2. Concept : 

Optical brighteners, optical brightening agents (OBAs), fluorescent brightening agents (FBAs) or fluorescent whitening agents (FWAs) are chemical compounds that absorb light in the ultraviolet and violet region (usually 340-370 nm) of the electromagnetic spectrum, and re-emit light in the blue region (typically 420-470 nm) by fluorescence. Fluorescent emission is a short-lived period of light emission by a fluorophore, unlike phosphorescence, which is long-lived. These additives are often used to enhance the appearance of color of fabric and paper, causing a "whitening" effect; they make intrinsically yellow/orange materials look less so, by compensating the deficit in blue and purple light reflected by the material, with the blue and purple optical emission of the fluorophore.

Jindaquan A-388 Brightening Agent :

Our Brightening agent A-388 is mainly made of Palmitic oil polymer and the Zinc stearate . which gives great gloss and brightness on the surface of the plastic products , thus remove the the old dull color appearance and make it looks as new as brightening and shinning again .  Also Our Brightening agent will improve the plastics polymers inner flow and dispersion, thus makes the finished products looks very smooth and comfortable, no lines problem.
