Type of resin used to produce plywood which has extremely low formaldehyde emissions. It is made from any synthetic resins made by reacting phenol (an aromatic alcohol derived from benzene) with formaldehyde (a reactive gas derived from methane). Phenols are similar to alcohols but form stronger hydrogen bonds. Thus, they are more soluble in water than are alcohols and have higher boiling points which do not break down under exterior end use conditions. Information developed by numerous organizations have consistently shown that formaldehyde emission associated with phenolic resin-bonded plywood is extremely low.
