Characteristics of Optical Brightener

OB-1 additive dissolves into plastic during the production process, helping products maintain their whiteness and brightness longer compared to other bleaching methods.

OB-1 additive belongs to the fluorescent agent category, absorbing ultraviolet light and emitting blue light. The blue light reflected from the product to the human eye masks the orange-red area, making the product appear whiter.

Applications

Optical brightener can be used for common plastics such as PE, PP, PS, etc.

Used in manufacturing industries: film blowing, foam bags, woven PP bags, non-woven fabric bags, etc.
