Mechanical, thermal and fire properties of sustainable rigid polyurethane foam derived from cashew nut shell liquid

  • Research Article
  • Published:
International Journal of Plastics Technology

Abstract

Global efforts to find renewable feed stocks for the chemical industry are aimed at replacing fossil reserves and a reduction in global warming by employing environmently friendly technologies (green chemistry approaches) for specialty chemical manufacturing. Cardanol obtained from “Cashew Nut Shell Liquid” (CNSL) is a renewable resource of immense potential. Present work describes the synthesis of bio-based polyol for rigid polyurethane foam via step wise oxazolidine route. Synthesized polyol was characterized by spectral analysis. The foaming characteristics were studied, and the polyol were successfully used in making rigid Polyurethane foams with good mechanical, thermal and fire properties.
