PUvaahto
PUvaahto, or polyurethane foam, is a polymer foam used mainly for insulation, sealing, and filling in construction and industrial applications. It is produced by the reaction of polyols with di- or polyisocyanates, often with blowing agents, catalysts, and additives that create a cellular structure and cure into a light, yet strong material.
There are two main forms. One-component polyurethane foam (OCF) expands in place when exposed to moisture and
Key properties of PUvaahto include low density, good thermal insulation, sound dampening, and strong adhesion to
Applications are broad but common in construction (thermal insulation, air sealing around pipes, doors and windows),
