The furans are a polymer family of thermosetting resins derived from furfural and furfuryl alcohol. There are a number of properties which make them attractive to the chemical process industry. In particular is their resistance to attack by either nonoxidizing acids or alkalies of any concentration. In addition, they are resistant to many hydrocarbons, both aliphatic and aromatic. They have excellent resistance to moisture and they can withstand continuous exposure to temperatures as high as 275°F. (135°C.) and intermittent temperature to 300°F. (150°C.). In spite of these properties -- which extend the usefulness of the furans in many areas beyond that of polyesters, vinylesters and epoxies, they have not been used extensively. There are two major reasons for the limited acceptance: One is the high cost of equipment, resulting from difficulties in fabrication. The second is the brittle nature of the cured system, which is due to the high degree of crosslinking in the molecular structure.
