Polymethyl methacrylate ine mashoma emagetsi zvimiro pane asiri-polar epurasitiki senge polyolefins uye polystyrene nekuda kweiyo polar methyl ester boka padivi pecheni huru.Iyo polarity yeboka remethyl ester haina kunyanyokura, uye iyo polymethyl methacrylate ichine yakanaka dielectric uye magetsi insulating zvivakwa.Izvo zvakakosha kucherechedza kuti polymethyl methacrylate uye kunyangwe iyo yese acrylic plastiki ine yakanakisa arc kuramba.Pasi pechiito chearc, iyo yepamusoro haiburitse kabhoni conductive nzira uye arc track phenomena.20 ° C tembiricha yekuchinja yechipiri, inoenderana nekushisa uko divi remethyl ester boka rinotanga kufamba.Pazasi pe20 ° C, iyo yedivi methyl ester boka iri munzvimbo yakaomeswa nechando, uye zvemagetsi zvezvinhu zvinowedzerwa pamusoro pe20 ° C.
Polymethyl methacrylate ine yakanaka yakazara mechanicha zvivakwa uye iri kumberi kwese-chinangwa mapurasitiki.Kusimba kwekusimba, kusimba kwesimba, kudzvanya uye mamwe masimba akakwira kupfuura epolyolefins, uye akakwira kupfuura ayo epolystyrene uye polyvinyl chloride.The impact kuoma kwakashata.Asi zvakare zvishoma zviri nani pane polystyrene.Iyo yakakandwa yakawanda polymethyl methacrylate shiti (senge aerospace plexiglass sheet) ine yakakwira mechanic zvimiro zvakaita sekutambanudza, kukotama uye kudzvanya, uye inogona kusvika padanho reinjiniya mapurasitiki senge polyamide uye polycarbonate.
