Description

REVA™ BBU 250% is positioned as a concentrated optical brightener grade. Concentrated grades can help manufacturers achieve target brightness levels using a suitable addition rate, provided the product is compatible with the production process.

The manufacturer’s published textile page lists a REVA BBU 250 grade with an E Value of 440 ± 25 and active content of 78–82%. However, those values should not automatically be applied to a paper-specific product listing without confirming the exact grade and application.
