I-Polymethyl methacrylate inezinto zikagesi ezincane kunezipulasitiki ezingezona ze-polar njenge-polyolefin ne-polystyrene ngenxa yeqembu le-polar methyl ester eceleni kweketango eliyinhloko.I-polarity yeqembu le-methyl ester ayinkulu kakhulu, futhi i-polymethyl methacrylate isenezici ezinhle ze-dielectric kanye ne-electric insulating.Kuyaqapheleka ukuthi i-polymethyl methacrylate kanye nayo yonke ipulasitiki ye-acrylic inokumelana okuhle kakhulu kwe-arc.Ngaphansi kwesenzo se-arc, indawo engaphezulu ayikhiqizi izindlela ze-carbonized conductive kanye ne-arc track phenomena.I-20 ° C izinga lokushisa lesibili lokuguquka, elihambisana nezinga lokushisa lapho iqembu le-methyl ester liqala ukuhamba.Ngaphansi kuka-20 ° C, iqembu le-methyl ester eseceleni lisesimweni esiqandisiwe, futhi izakhiwo zikagesi zezinto ezisetshenziswayo zenyuka ngaphezu kuka-20 ° C.
I-Polymethyl methacrylate inezici ezinhle zokuhlanganisa eziningi futhi iphambili kumapulastiki enhloso evamile.Amandla aqinile, amandla okuqina, ukucindezela namanye amandla aphakeme kunalawo e-polyolefin, futhi aphakeme kunalawo e-polystyrene ne-polyvinyl chloride.Ukuqina komthelela kubi.Kodwa futhi kancane kancane kune-polystyrene.Ishidi eliyinqwaba ye-polymethyl methacrylate (elifana neshidi le-plexiglass ye-aerospace) linezinto zomshini eziphakeme ezifana nokunwebeka, ukugoba nokuminyanisa, futhi lingafinyelela izinga lamapulasitiki obunjiniyela njenge-polyamide ne-polycarbonate.
