Paraformaldehyde CAS 30525-89-4 yog dab tsi?

Polyoxymethylene (POM) yog ib tug polymer ntawm formaldehyde (siab molecular hnyav polyoxymethylene) nrog ib tug raug structural ntev ntawm yim mus rau ib puas ib txoj hauj lwm. Cov saw ntev polyoxymethylene feem ntau yog siv rau hauv kev tsim cov khoom siv hluav taws xob kub-resistant, tseem hu ua polyoxymethylene plastics (POE, Derlin tsim los ntawm DuPont). Polyformaldehyde decomposes sai thiab tso tawm me ntsis fouling formaldehyde.
