Pennsylvania, US – PU additives manufacturer Evonik, has introduced new products for the spray polyurethane foam (SPF) industry. The new product from the German company – which has its PU innovation lab in Allenstown, Pennsylvania – is called Dabco PM 301.
The new product – designed to be used in combination with Opteon 1100 and Opteon 1150 blowing agents from global chemical manufacturer Chemours – is said to offer improved thermal performance and increased efficiency.
With the industry looking to phase out traditional, greenhouse-gas hydrofluorocarbon (HFC) blowing agents, Chemours’ Opteon hydrofluoroolefin (HFO) blowing agents offer an alternative which the company says significantly reduces global warming potential (GWP) and optimises the end-of life contribution of SPF.
According to the World Meteorological Organisation’s (WMO), 2018 Scientific Assessment of Ozone Depletion Research and Monitoring project, Opteon 1150 has a GWP of 16, which is 100 times lower than traditional HFC blowing agents.
“The need to reduce the GWP footprint and ozone depleting building emissions, while at the same time maintaining blowing agent compatibilization for SPF systems, requires innovative tools to help the industry best optimise new HFO blowing agents,” said Christian Eilbracht, head of the PU insulation business at Evonik.
“Dabco PM 301 significantly increases the efficiency and drives the thermal performance of our Opteon 1100 and Opteon 1150-based SPF systems,” said Joseph Martinko, a senior business director at Chemours. “Our portfolio of low GWP, non-flammable foam blowing agents made with HFO technology offer high performance insulation and thermal resistance in foam blowing applications to help our customers achieve the product reliability they demand with sustainable and energy efficient products.”
Dabco PM 301 is nonflammable and offers a reduction in the required use level of the blowing agent while maintaining foam physical properties.
