Low Pressure polyurethane one component foam systems (OCF) and two component foams systems (LP SPF) are primarily used to stop air infiltration by sealing or adding insulation to the building envelope. The use of these products includes but is not limited to, insulation, adhesives, gap fillers, air sealants, and patching products. Currently, HFC-134a is used extensively as a propellant and blowing agent in these products. However, there is a growing interest in environmentally friendly building products within the building community, specifically materials with a smaller environmental foot print. One consideration is the global wanning potential (GWP). Solstice GBA (HFO-1234ze(E)), an alternative to HFC-134a, has a GWP of less than 1 and can be an ideal replacement for HFC-134a. The transition from HFC-134a to Solstice GBA is expected to represent a 99.9% reduction in the GWP of these products. The focus of this poster will be the inclusion of Solstice GBA into these products via shelf life, product quality and product field performance evaluations.
