Ingabe ifilimu enamathelayo encibilikayo eshisayo iqukethe izinto eziyingozi njenge-formaldehyde?
Izingxenye eziyinhloko zefilimu yokunamathisela encibilikayo eshisayo yi-polymers yamangqamuzana aphezulu, okungukuthi, i-polyamide, i-polyurethane nezinye izinto.
Zinezinga eliphezulu le-polymerization, ngakho-ke azilimazi emzimbeni womuntu. Ngesikhathi esifanayo, ifilimu yokunamathisela eshisayo eshisayo iyamanzisa
ubuso bezinto ezinamathele ngokufudumeza nokuncibilika, futhi ayidingi i-solvent ukusiza ukumanzisa impahla.
Ngakho-ke, ifilimu ye-adhesive eshisayo encibilikayo iyi-adhesive enobungani bemvelo engenawo i-formaldehyde noma i-solvents.
