Fireblock Single Component Spray Polyurethane Foam

A Common Product profile (CP) is a type of data record originally developed as part of a collaboration called the Quartz Project. The profiles are not specific to any manufacturer, but list the substances that are most commonly present in a product type. The CPs include a general description of the product type, a list of the most common substances serving each function in the product, and the health hazards associated with these substances. See the CP methodology here for more information.

This CP presents research done by Healthy Building Network alone following the completion of the Quartz effort.

Description:

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.

This information reflects our best understanding of product composition in 2016.
