Polymethyl methacrylate waxay leedahay hanti koronto yar marka loo eego balaastikada aan polarka ahayn sida polyolefins iyo polystyrene sababtoo ah kooxda methyl ester polar ee dhinaca silsiladda weyn.Polarity ee kooxda methyl ester ma aha mid aad u weyn, iyo polymethyl methacrylate weli waxay leedahay sifooyin koronto oo wanaagsan.Waxaa xusid mudan in methacrylate polymethyl iyo xitaa balaastikada acrylic oo dhan ay leeyihiin iska caabin aad u fiican.Marka la eego ficilka arc, dusha sare kama soo saaro waddooyinka kaarboonaysan iyo dhacdooyinka raad-raaca.20 ° C waa heerkul kala-guurka labaad, oo u dhiganta heerkulka ay kooxda methyl ester-ka ay bilaabaan inay dhaqaaqaan.Ka hooseeya 20 ° C, kooxda methyl ester dhinaca waxay ku jirtaa xaalad barafaysan, iyo sifooyinka korantada ee walxaha ayaa kor u kacay 20 ° C.
Methacrylate Polymethyl waxay leedahay sifooyin farsamo oo dhammaystiran oo wanaagsan waxayna safka hore kaga jirtaa balaastikada ujeeddada guud.Awoodda xajinta, xoogga jilicsanaanta, cadaadiska iyo xoogga kale ayaa ka sarreeya kuwa polyolefins, oo ka sarreeya kuwa polystyrene iyo polyvinyl chloride.Saameyntu way liidataa.Laakiin sidoo kale wax yar ka fiican polystyrene.Xadhkaha bulk polymethyl methacrylate (sida xaashida aerospace plexiglass) waxay leedahay sifooyin farsamo oo sare sida kala jiidashada, foorarsiga iyo isku xidhka, waxayna gaadhi kartaa heerka balaastikada injineernimada sida polyamide iyo polycarbonate.
