CAS 30525-89-4?
Tus lej lej 30525-89-4 yog hais txogPararormaldehyde (Pfa). Nws yog cov polyoxymethyletylene, cov khoom lag luam polymerization ntawm formaldehyde nrog ib tug℃ntawm polymerization ntawm 8-100 units. Parma formaldehyde feem ntau muaj tsw me me ntawm formaldehyde vim kev txiav txim siab. Pararormaldehyde yog poly - acetal.
Pfa pararormaldehydeYog cov lag luam linear polymer ntawm formaldehyde. Pararormaldehyde yog qhov sib tov ntawm tsawg molecular hnyav ntawm polyoxymethylene glycols. Tus polymer no coj ua tshuaj lom li ib qho khoom ntawm formaldehyde. Nws yog ntau dua ruaj khov thiab haum rau ob qho tib si rau kev khaws ntaub ntawv thiab kev lag luam.
