Passionate About Polyurethane

Pour in Place

Pour-in-place polyurethane foam systems from FSI provide superior thermal performance, robust processing characteristics and excellent finished properties for efficient manufacturing and high performance across a wide range of applications.


Ecofoam® rigid pour-in-place foam with Ecomate® blowing agent technology offers superior thermal insulation performance and other physical properties and wide processing latitude.



Ecostar rigid pour-in-place foam with Ecomate blowing agent technology is certified ASTM E84/UL-723 Class I (A) rated. It offers the same superior thermal insulation, physical properties and processing characteristics as Ecofoam systems but with the burning characteristics required by certain building codes and industry-specific requirements.

Ecostar rigid pour-in-place foam with Ecomate blowing agent technology is certified ASTM E84/UL-723 Class I (A) rated
Conti Foam


Conti-Foam rigid foam is designed for continuous double belt lamination applications such as architectural panels, garage doors and other metal- and foil-faced products.



Genfoam – 100% water-blown rigid pour-in-place systems which are suitable for producing molded parts where thermal performance is not critical, such as composite cores, flotation, decorative trim, artificial landscaping and taxidermy.
