Tests showed that PF resin modification with diol esters makes it possible – when maintaining identical pressing parameters – to manufacture particleboards with improved mechanical properties and enhanced water resistance in comparison to the control board resinated with pure PF resin. The application of diol esters as modifiers of phenolic resin makes it also possible to produce – at reduced temperature or shortened pressing time – particleboards with good mechanical properties and high water resistance. However, no significant differences were observed in board properties depending on the type of diol forming the ester.
