STI SSWBLU BLU Wrap Strip 12' x 2" x 3/16" Roll

STI SSWBLU BLU Wrap Strip 12’ x 2” x 3/16” Roll

SpecSeal Wrap Strips are highly flexible, elastomeric strips designed to firestop combustible penetrations in fire-rated floors, floor/ceilings, and walls. Convenient 12 ft (3.7 m) rolls.

These products utilize STIs fast responding intumescent technology, providing very responsive and highly directionalized expansion. Rapid expansion provides quick closure for burning combustible penetrants.

When exposed to temperatures in excess of 250deg F (121 deg C), the SpecSeal® Wrap Strip begins to expand (intumesce) rapidly to form a dense, highly insulative char. Free expansion varies according to the grade utilized (See Table A). Expansion continues up to temperatures of 1,000deg F (538 deg C).
