Isoexter

The ISOEXTER line consists of polyester polyols used in the production of rigid polyurethane insulating foams.

Materials in this line combine easy processability with excellent mechanical, fire resistance and thermal insulation properties.

End-use applications include insulating panels (continuous and discontinuous), appliances, block foams, one-component foams (OCFs), sprays and imitation wood.

COIM is committed to sustainable product development, environmentally responsible operations, and supporting our customers in their sustainability efforts. Nearly all ISOEXTER products contain pre-consumer recycled and rapidly renewable content, with many of the core materials carrying Underwriters Laboratories (UL) validated claims.
