iBright® optical brightener agent for polymer

iBright® 393 OB-1

Optical Brightener Agent for Plastics and Synthetic Fibers

iBright® 393 OB-1 is optical brighteners create brilliance by a fluorescence process involving absorption of invisible UV light and emission of visible blue light. iBright® 393 OB-1 is especially useful in polyester and nylon fibers, as well as in high temperature engineering plastics, and  also applicable for polyolefin plastics.

Main Advantage

• Improves whiteness wither than white
• Provides brighter looking colors
• Low volatility and excellent heat resistant, ideal for use in polyester fibers, nylon fibers and in engineering plastics processed at high temperatures
• Good light fastness
• Chemically stable

Main Application

iBright® 393 OB-1 is recommended to increase the whiteness of polyester and polyamide fibers as well as high temperature engineering plastics, including polycarbonates, polyesters, and polyamides (nylon). The product can also be used in styrenic and acrylic polymers.
