Furfural or Furfuryl Alcohol Suppliers Manufacturers

Furfuryl alcohol has been used in rocketry as a fuel which ignites hypergolically (immediately and energetically in contact) with white fuming nitric acid or red fuming nitric acid oxidizer Because of its low molecular weight furfuryl alcohol can impregnate the cells of wood where it can be polymerized and bonded with the wood by heat radiation and/or catalysts or additional reactants
