Polymethyl silicone resin feem ntau yog copolymer tsim los ntawm siloxane chain units xws li SiO3/2, CH3SiO3/2, (CH3)3SiO2/2, (CH)SiO1/2. Siv cov khoom siv raw nrog tsuas yog ob lossis tsawg dua methyl pawg txuas rau txhua lub silicon atom (xws li methyltrichlorosilane, dimethyldichlorosilane), polymethylsiloxane resin nrog cov qauv network tuaj yeem tau txais, uas tuaj yeem hloov mus rau hauv Insoluble infusible khoom.
