ABSTRACT

The conversion from R-14IB to suitable alternate blowing agents in the rigid foam markets has accelerated as the deadline for its disappearance nears. Pentanes have been selected by the flexible faced laminate industry to replace R-141B. Plant conversions are underway. Other foam applications are considering pentanes. One such large application is the metal faced panels using pour-inplace systems.

The work reported here will show that if properly formulated, systems containing pentanes can be used in this application. The paper will show several fire retardant combinations needed to reach the desired results in the E-84 Tunnel Test.
