Due to its large branching, polymethyl methacrylate has a high viscosity, so the processing speed is slow when using the hot working method. The plexiglass can be cut not only by a lathe, but also by a drilling machine, and acetone can be used. The chloroform and other materials that are bonded into various shapes can also be processed into plastic hulls, such as blow molding, injection, extrusion, and the like, from small cockpit covers to dentures and trays.
The cyanoacrylate, methylene chloride or chloroform can dissolve the plexiglass slightly, and then the two plexiglass can be firmly bonded together.
Producing 1 kg of PMMA requires about 2 kg of oil. In the presence of oxygen, PMMA begins to burn at 458 ° C and burns to produce carbon dioxide, water, carbon monoxide and some low molecular compounds including formaldehyde.
