A Tufflam Green Phenolic FRP Sheet refers to a type of phenolic resin-based laminated sheet, typically characterized by its green color and 5mm thickness. Tufflam is a brand or variation of phenolic plastic sheets, known for their excellent mechanical, electrical, and chemical properties.

This GPO 1 Tufflam FRP Sheet is composed of random mat (non-woven) fiberglass reinforcement held together by a polyester resin binder. (Polyesters are versatile resins, which handle much like epoxies. Of course, the basic resins are chemically different. It is their physical application forms, which make them similar. Despite lower costs, the important disadvantages of polyesters, as compared with epoxies, is lower adhesion to most substrates, higher polymerization shrinkage, and a greater tendency to crack during cure or in thermal shock and greater change of electrical properties in a humid environment.) GPO-1 offers the least arc resistance.
