Kupatula kuchuluka kwa ma polymerization ndi magulu omaliza, kutentha kumakhudzanso kukhuthala kwa PDMS (mafuta a silicone ali ndi mawonekedwe a kachulukidwe kakang'ono -kutentha kokwanira, koma kukhuthala kwake kumatsikabe pakatentha kwambiri), koma uku ndikusintha kwakuthupi m'malo mosiyana ndi kukhuthala komwe kumachitika chifukwa cha kapangidwe kake.
Mlingo wa polymerization ndiye chinthu chofunikira kwambiri pozindikira kukhuthala kwa PDMS. Kusiyana kwa kutalika kwa unyolo wa ma cell kumabweretsa kusiyanasiyana kwa viscosity pakati pa mitundu yosiyanasiyana ya PDMS, pomwe chikoka cha magulu omaliza ndi kutentha ndi chachiwiri. Mu ntchito zothandiza (monga kupukuta pansi, mafuta odzola, etc.), ndikusankha PDMS yokhala ndi magawo osiyanasiyana a polymerization kuti magwiridwe antchito a viscosity agwirizane.
