Talca, Chile – A group at the Universidad Catolica del Maule has developed a novel eco-friendly polyurethane foam. It is based on a polyol made from oil derived from Lesquerella fendleri (A. Grey). This is a member of the mustard family, otherwise known as Fendler’s Bladderpod or Popweed.
Chilean group creates alternative biopolyol
The polyol was made in a one-step reaction from the plant oil, and then reacted with MDI and used to make PU foam. Analysis showed that the foam had a microporous structure with a combination of both open and closed cells.
According to the group, the foam has the potential to be an ‘ecological and cheap substitute for petroleum-based polyurethane foams’.
