Icynene Introduces Spray Foam with Rapidly Renewable Content

Icynene, maker of the widely used and first open-cell polyurethane spray foam insulation of the same name, has launched a new product with some rapidly renewable content. Icynene LD-R-50 is formulated with a polyol derived from the castor plant—a shrub with two annual growing cycles that thrives on marginal land.

EBN that the product would contain a minimum 7% renewable content by weight. Like its petroleum-derived counterpart, Icynene LD-R-50 is a water-blown, HFC-free product that functions as an air barrier as well as insulation. According to Icynene, the new formula offers a slightly higher insulation value—R-3.7 vs. R-3.6 per inch—at a comparable cost. Visit www.icynene.com for more information.
