PS Brightener OB & OB-1 is a heat resistant and chemically stable fluorescent whitener that increases whiteness and provides brighter looking colors.

It is used to offset the yellowness of a polymer and to yield a whiter appearance. PS Brighteners create brilliance by a fluorescence process involving absorption of invisible UV light and emission of visible blue light.

PS Brightener OB & OB-1 is especially useful in PE, PP, polyester and nylon fibers as well in high temperature engineering plastics.

• Brilliant, bluish white effects that compensates for yellowing
• Good light fastness and low volatility.
• Exceptional whitening properties.
• Highly compatible with a wide range of organic substrates and solvents.
• Excellent resistance to heat.
