Usibye urwego rwa polymerisation hamwe nitsinda ryanyuma, ubushyuhe nabwo bugira uruhare runini mubwiza bwa PDMS (amavuta ya silicone afite ibimenyetso biranga ubukonje buke -, ariko ubukonje bwayo buracyagabanuka kubushyuhe bwo hejuru), ariko iyi ni ihinduka ryimiterere yumubiri aho kuba itandukaniro ryimiterere yimiterere iterwa nuburyo bwimiti.
Urwego rwa polymerisation nicyo kintu cyingenzi kigena ubwiza bwa PDMS. Itandukaniro ryuburebure bwa molekuline riganisha ku buryo butaziguye bwo guhindagurika hagati yubwoko butandukanye bwa PDMS, mugihe ingaruka zitsinda ryanyuma nubushyuhe ari ubwa kabiri. Mubikorwa bifatika (nka polish hasi, lubricants, nibindi), mubyukuri muguhitamo PDMS hamwe na degere zitandukanye za polymerisiyoneri nibikorwa bya viscosity bisabwa bihuye.
