K-FLEX LS
Closed Cells Flexible Elastomeric Foam

K-FLEX® LS is a flexible, closed-cell elastomeric insulation product used to conserve energy and prevent condensation on piping applications. The product's closed-cell structure creates exceptional thermal properties (k-value of 0.245 at 75F and wvt of 0.03 perm-in) that protect against moisture penetration in applications within a -297°F to +220°F temperature range.

K-FLEX® LS is widely used in the commercial and industrial markets for its cold weather flexibility, durable skin surface, exacting manufacturing tolerances and lasting performance. K-FLEX® LS Tube is non-porous, non-fibrous and resists mold, fungal and bacterial growth. For added protection, it is protected with an EPA-approved antimicrobial agent. K-FLEX® LS Tube is GREENGUARD® certified under the Children and Schools classification, is approved through supervision by the Factory Mutual Research Corporation, and is 25/50-rated up to 2" wall thickness when tested to ASTM E 84 standards.
