Hot-wire foam cutter. simple styrofoam cutter. A hot-wire foam cutter is a tool used to cut polystyrene foam and similar materials. The device consists of a thin, taut metal wire, often made of nichrome or stainless steel, or a thicker wire preformed into a desired shape, which is heated via electrical resistance to approximately 200Â°C.
The plastic is polymer. Polymers can be thermal and electrical insulators. For example, pots and pans handles are made of polymers, so are insulated cups, coolers, and microwave cookware. Remember that styrofoam is a trademarked name of the Dow chemical company for its brand of polystrene foam. It works by reducing a process known as heat transfer.
