Lightweight rigid board for creative work

Pacon 5557 foam core board is a polystyrene sheet laminated between two paper faces, giving a smooth satin surface that accepts paint, markers and adhesives. Each sheet measures 22 by 28 inches at 187.5 mil thickness and cuts cleanly without warping or denting. The five-pack supplies enough material for classroom activities, mounting, framing or display projects.

Buyers needing heavy structural panels

This board suits teachers, students, artists and exhibitors who want a light, easy-to-cut surface for indoor graphics and crafts. It is not designed for load-bearing construction, outdoor exposure or applications that require waterproof or fire-rated substrates.

187.5 mil thickness defines rigidity

The 3/16 inch foam core determines how stiff the sheet feels, how cleanly it scores and whether it fits standard poster racks. Match this dimension to your project requirements before ordering.

Questions about this item

How do I cut the 187.5 mil foam board cleanly without crushing the polystyrene core?

Score the paper liner with a sharp utility knife and metal straightedge, then snap the sheet along the score line; the polystyrene core breaks cleanly when the cut is deep enough.

Will the paper facing yellow or delaminate if the board is displayed long-term?

The polystyrene core resists warping and denting, but the paper liners are not acid-free, so prolonged UV exposure can cause gradual yellowing and brittleness.

At what span does a 22 x 28 inch sheet start to bow under its own weight when mounted vertically?

The 3/16" thickness keeps the board rigid for typical signage, but unsupported vertical spans approaching the 28-inch width may show a slight bow over time.
