FR Foam Technical Specifications

Frequently Asked Questions About FR Foam

What is Fire retardant PU foam?

It means fire-retardant foam. In polyurethane applications, FR PU foam is formulated to provide fire-retardant performance in addition to sealing and insulation properties.

What is B1 FR PUF Sealant?

It is a polyurethane foam classified as B1 under DIN 4102. It is intended for applications where a higher level of fire-retardant performance is required.

Where is Fire rated PU foam used?

Fire rated PU Foam is commonly used for gap filling, sealing and insulation around doors, windows, walls, ceilings, panels, electrical installations, ducts and building penetrations.

Is Fire rated foam suitable for construction?

Yes. it can be used for sealing and insulating suitable gaps and cavities where fire-retardant and insulation properties are required.

Does FR puf sealant make a building completely fireproof?

No. It should not be considered a material that makes a structure completely fireproof. Its fire performance and suitability depend on the product classification, application, surrounding materials and overall fire-safety system.

How long does FR PU foam take to cure?

The curing time depends on temperature, humidity, application thickness and other conditions. Anaghafoam FR has a reported tack-free time of approximately 8–10 minutes and a cutting time of approximately 30–40 minutes.

Can cured foam be painted?

After the foam has fully cured, excess material can be trimmed and the surface may be finished with compatible coatings or plaster, subject to application requirements.
