Essen, Germany - Evonik is due to deliver two technical papers on polyurethane additives at this year's US Centre for the Polyurethane Industry (CPI) conference in Nashville, Tennessee.
Evonik's Comfort & Insulation business unit, previously known as the Polyurethane Additives unit, will present papers on the benefits additives can bring to the rigid boadstock and flexible slabstock industries.
In a 5 July announcement, Evonik said the first paper is "targeting changes taking place in the rigid boardstock industry" whereas the second one is related to "conventional flexible slabstock applications based on renewable resources."
The first paper deals with Evonik's observation that more producers are switching to hydrocarbon blowing agents due to growing concerns about climate change and ozone depletion. Evonik said the paper addresses the challenges related to the different properties that these materials bring to the foam system.
The second paper focuses on the increased interest within the PU industry to use natural oil-based polyols, which can change the processing and physical properties of flexible slabstock foam.
Evonik will be giving the papers at the 2011 CPI technical conference, held 26-28 Sept, in Nashville, Tennessee.
