More about Fireblock Single Component Spray Polyurethane Foam

Single component polyurethane spray foam comes in a range of products with different properties for different applications. This product is supplied in a can for either direct application with a straw or application with a special gun. The general composition includes one or more isocyante, polyol, catalyst, hydrocarbon propellant/blowing agent, surfactant, and flame retardant. Typically, the isocyanate portion (MDI and/or PMDI) is mixed with the polyol portion, including additives, and then reacts to some extent in the can. This creates a prepolymer which further reacts with moisture in the air when applied on site. While there are many types of single component spray foam, the composition is typically similar, with minor differences in percentage of components. This CP covers specifically a fireblock spray polyurethane foam intended to fill gaps around HVAC penetrations and plumbing/electrical penetrations and through stud penetrations. These products are tested according to ASTM E814 (modified) and approved as a Type V residential fireblock. They are orange in color so as to be readily identifiable after installation. The formulations are similar to other single component SPF but typically contain a greater total precentage of flame retardant.
