Mbiri ya Plexiglass

Mu 1927, katswiri wa zamankhwala ku kampani ya ku Germany anatenthetsa acrylate pakati pa mbale ziwiri zamagalasi, ndipo acrylate polymerized kuti apange interlayer yofanana ndi mphira wa viscous yomwe ingagwiritsidwe ntchito ngati galasi lotetezera kusweka.Atapanga polymerized methyl methacrylate mwanjira yomweyo, mbale ya plexiglass yokhala ndi zowonekera bwino komanso zinthu zina zidapezeka, zomwe zinali polymethyl methacrylate.

Mu 1931, kampani ya ku Germany inamanga chomera chopangira polymethyl methacrylate, yomwe idagwiritsidwa ntchito koyamba pamakampani opanga ndege, m'malo mwa mapulasitiki a celluloid opangira ma canopies a ndege ndi ma windshields.

Ngati mitundu yosiyanasiyana imawonjezedwa popanga plexiglass, imatha kupangidwa ndi ma polymer mu plexiglass yamitundu;ngati fluorescer (monga zinki sulfide) iwonjezedwa, akhoza polymerized mu fulorosenti plexiglass;ngati pearl ufa wopangira (monga lead lead carbonate) wawonjezedwa, pearlescent plexiglass imatha kupezeka.
