Description
Cyclopentane 99% (CAS No. 287-92-3) is a high-purity industrial grade. Specifically, it suits applications where tighter impurity control matters. Beyond standard PU foam blowing, this grade works well in higher-performance insulation systems, resin and adhesive formulation, and laboratory use.
Because trace impurities can affect process consistency and product performance in these applications, this grade meets tighter tolerances than the standard 95% commercial grade. However, for bulk-volume PU foam production where cost efficiency matters most, see Cyclopentane 95%.

Applications for Cyclopentane 99%
What’s more, because higher-performance PU/PIR foam systems and specialty applications are more sensitive to trace impurities, this grade supports demanding foam formulations along with resin, adhesive, and chemical intermediate production. It also works as a solvent and reference material for laboratory and analytical use. As a result, manufacturers with tighter process tolerances typically choose this grade over the 95% option.
