Application area Classification Addition rate
Construction DIN 4102 5-10 parts Exolit AP 422 /
Class B2 100 parts polyol (blowing agent
pentane, NCO index 250, combined
with other non-halogenated liquid
flame retardants)
Class B1 15 parts Exolit RP 6580/100 parts
polyol (blowing agent R 141b,
high NCO index combined with
additional TCPP)
NF P 92-501 10-15 parts Exolit RP 6580/100 parts
Class M1 polyol (blowing agent R 141b,
high NCO index combined with
additional TCPP)
The addition rate to achieve a specific fire classification depends heavily on the polyol, blowing agent and foam density.
