What is Polyurethane?

According to Google, it’s a “synthetic resin in which the polymer units are linked by urethane groups, used chiefly as constituents of paints, varnishes, adhesives, and foams.” Its application ranges from building insulation, mattresses, coatings, adhesives, composite wood panels, shoe soles and even mudjacking. While polyurethanes are marketed as “versatile, modern and safe,”¬†some manufacture safety data sheets show that polyurethanes are ‘extremely flammable aerosols, may cause allergic skin reactions, causes serious eye irritation, harmful if inhaled, suspected of causing cancer,’ and much more

A simple Google search suggests this stuff is nasty, still, companies who use it as a daily application for ‘solutions,’ continue to deny the claims.

To be sure, we’ve reached out to the EPA for an official comment. We’ll update this post once we’ve received¬†an update.
