[1] "Formvar" used to be the registered trade name of the polyvinyl formal resin produced by Monsanto Chemical Company in St. Louis, Missouri.

[2] Formvar is used in many different applications, such as wire insulation, coatings for musical instruments, magnetic tape backing, and support films for electron microscopy.

[3] Formvar is also used as a main ingredient for special adhesives in structural applications such as the aircraft industry.

[5] Most specimens used in transmission electron microscopy (TEM) need to be supported by a thin electron-transparent film to hold the sample in place.

Formvar resin has a high softening point and strong electric insulation properties.
