Exaphen polyols are developed from renewable and natural chemical structures with an alkyl-phenolic skeleton, thus being characterised by unique properties related to their reactivity, compatibility with standard components and improved performances when compared to other Crude and Natural Oil Polyols. Examples are shown with the case studies section of our brochure.
Specifically, ExaPhen is based on the well-known structure of cardanol (Figure 1), an industrial oily alkyl-phenolic product (having up to 3 unsaturations in the flanking alkyl chain) obtained by vacuum distillation of “cashew nut shell liquid” (CNSL), extracted from the cashew of Anacardium Occidentale.
Select below the application for rigid PUR that you are interested in and find our specific recommendation of ExaPhen polyols for your case.
