- Functions:Optical Brightener
- Pigment Type:Inorganic Pigments
- Color:White
- Compatible Polymers & Resins:Polyethylene Terephthalate (PET), Polyamides, Polypropylenes (PP)
Articles made with thermoplastic polymers are often required to have an improved and brilliant white appearance. PP, PA, PET fibers, whether colorless or white-pigmented, can be produced in brighter and more attractive shades by incorporating selected additives based on optical brighteners. Optical brightner masterbatch enhance the whiteness and compensate the original inherently yellowish shade of many thermoplastic polymers.
