Appendix X Open-Cell

UPC’s 500 OCX is taking the Appendix X spray foam market by storm! A sucrose-based formula that sprays just like a traditional open-cell foam, with no fuss, without clogging the gun, and with exceptional yield. The chemistry gives you the ability to spray consistently on-ratio and with exceptional controllability. Sprayers find the 500 OCX is the easiest “sugar” based foam they’ve ever worked with. For design professionals, the 500 OCX is one of the few low-density fire-rated formulas to pass the AC377 Appendix X - enabling you to leave the foam exposed in design assemblies where ignition barriers are required.
