Optical brighteners are designed to brighten colors or mask yellowing of plastic products. They work through a fluorescent mechanism, absorbing light in the UV spectrum and emitting it in the blue range of the visible spectrum, resulting in a brighter, fresher appearance : e.g. white colored products appear whiter to the human eye.
INTABRIGHT is supplied in pellet form to obtain effective and homogenous distribution in the raw material mixture during processing.
INTABRIGHT is suitable for products such as plastic films, woven bags, bottles, houseware, containers especially cosmetic containers, etc.
