A basic (alkaline) catalyst and, usually but not necessarily, a molar excess of formaldehyde is used to make resol resins.
Special phenolic resins in combination with the proper cure catalysts, surfactants and blowing agents produce foam products. Phenolic foam has a unique set of properties such as excellent fire and heat resistance and a low smoke and toxicity rating when burned. Proper surfactants produce closed cell foams with excellent insulating R-values. Other surfactants produce open cell foams demonstrating unique water absorption properties. Typical application fields are:
Resole phenolic resins are widely accepted by the foam industry for their superior consistency, crucial for the challenging production process.
