OPTICAL BRIGHTENERS

The REPI OPTICAL BRIGHTENERS are organic additives that absorb ultraviolet light and re-emit most of the absorbed energy in the visible spectrum, giving polyurethane products a brighter and fresher appearance. They are specifically designed for flexible, rigid, and semi-rigid foams, as well as for C.A.S.E. applications used in the automotive, furniture, footwear, construction, marine, and offshore industries. Suitable for neutral, white, and colored foams, REPI OBs can be used as a component in the polyol or added separately in the mixing head.
