ynene’s next generation of high performance product, ICYNENE LD-R-50®, is a renewable based,0.5 lb., spray foam insulation and air barrier material. ICYNENE LD-R-50 exceeds the renewable content specification set by the USDA BioPreferredSM program and ICC-SAVE. Using high-yield castor oil material, ICYNENE LD-R-50 reduces the need for petroleum-based polyol. Castor oil is a natural ingredient that is safe enough for use in personal care products such as lip balm.

CASTOR OIL: Environmental Overview*
Castor oil is 100% naturally filtered, no chemical additives required.
Castor crops are non-irrigated (relying only on natural rainfall), saving scarce water supplies.
Castor beans do not require pesticides or fungicides.
Production process has low energy dependence, consisting of simply de-husking and pressing. Harvesting is manual.
The castor oil used has a yield (by weight) of ~40% vs. ~17% yield with soya oil.
Castor beans do not compete with food crops, as castor plants can be grown on
marginal lands, which are not competitive with food production lands.
Castor is a rapidly renewable material, as per USGBC definition, requiring a 10-year
or less re-growth timeframe.
