Description

 

Paraformaldehyde is the smallest polyoxymethylene. It is used as fumigant, disinfectant, fungicide, and fixation, and for the preparation of pure formaldehyde. Longer chain-length polyoxymethylenes are used as thermoplastic and are known as polyoxymethylene plastic. It was used in the past in the discredited Sargenti method of root canal treatment.
