Description:


This EPA SBIR Phase I Research and Development proposal will demonstrate feasibility of reduction
in halogenated flame retardant use in polyisocyanurate foams prepared from lignin- content rPET
polyols.  The study will show whether or not the lignin rPET polyol formulations meet ASTM flame
retardancy standards and thus reduce or eliminate the need for halogenated fire retardants (HFRs}
in spray foams used for insulation in interior building construction.

The Resinate novel material may reduce harmful environmental toxins that studies show affect human
health. Since their introduction in the 1970's, halogenated flame retardant chemicals have become
widespread global contaminants. In humans, these substances are associated with abnormalities
(Meeker & Stapleton 2009}, diabetes (Lim et al. 2008}, thyroid dysregulation (Turyk et al. 2008,
Meeker et al. 2009}, cognitive changes (Roze et al. 2009, Herbstman et al. 2010}, and
cryptorchidism (Main et al. 2007.}

Lignin is the second most abundant biorenewable agricultural material on earth and is often
discarded as waste material from pulp and paper production. The research may result in greater than
90% of recycled and biorenewable content in spray foam market applications without the use of
halogenated flame retardants in addition to biobased content that meets the USDA

Biopreferred labeling standards.
