phenol-formaldehyde resin

[′fē‚nȯl fər′mal·də‚hīd ‚rez·ən]
(organic chemistry)
Thermosetting resin made by the reaction of phenol and formaldehyde; has good strength and chemical resistance and low cost; used as a molding material for mechanical and electrical parts. Originally known as Bakelite.

phenol-formaldehyde resin, phenolic resin

A thermosetting, waterproof, low-cost, mold-resistant, high-strength synthetic resin made from phenol and formaldehyde; has good resistance to aging; used extensively in the manufacture of adhesives, exterior and marine plywood, laminated products, and molded articles.

* Use of high-density polyethylene, polyurethane, and polyamide-6 textile fibre waste hot-melts for wood veneer gluing guarantees the shear strength (5.6-10 MPa) of the material that considerably exceeds the adhesive strength of industrial plywood (2.5-3.7 MPa) glued with phenol-formaldehyde resins.
There is less pressure to convert exterior-grade wood products because they use phenol-formaldehyde resins, which offgas formaldehyde at a much lower rate than the urea-formaldehyde resins.

These adhesives include thermoplastic adhesives, such as polyvinyl acetate, and thermosetting adhesives, such as urea-formaldehyde, melamine-urea-formaldehyde, and phenol-formaldehyde resins. Thermoplastic adhesives are widely used in the furniture industry, while thermosetting adhesives are widely used in manufacturing plywood and particle board.
