Paraformaldehyde CAS 30525-89-4 ke eng?

Polyoxymethylene (POM) ke polymer ea formaldehyde (high molecular weight polyoxymethylene) e nang le bolelele ba sebopeho sa maemo a robeli ho isa ho a lekholo a le mong. Polyoxymethylene ea ketane e telele e atisa ho sebelisoa ha ho etsoa lipolasetiki tse thibelang mocheso, tse tsejoang hape e le polyoxymethylene polasetiki (POE, Derlin e hlahisoang ke DuPont). Polyformaldehyde e bola ka potlako 'me e ntša formaldehyde e nkhang hampe hanyenyane.
