Bright White Acid-Free Foam Board

The Professional Framer's Choice – Totally Acid-Free

EnCore® Bright White Acid-Free Foam Board is whiter than the whites you’ve used before. As a result, it dramatically enhances colors of any artwork.

Its pH between 7.7 and 8.5 calcium carbonate buffer prevents acid migration from the foam board that would cause irreparable damage to the paper items being mounted.
