Lesi sihloko sihlola umthelela wohlobo lwe-platinum catalyst kanye nokugxila ku-crosslinking kinetics yerabha ye-silicone yokwelapha. Izinhlobo ze-Catalyst: I-Speier catalyst (i-chloroplatinic acid, i-Pt⁴⁺) idinga ukuncishiswa kwezinhlobo ezisebenzayo ze-low-valent, ezisebenza njenge-precatalyst; I-Karstedt catalyst (Pt⁰ ene-divinyltetramethyldisiloxane) ingena ngokuqondile kumjikelezo we-catalytic. Imithelela yohlobo: I-Speier ibonisa isikhathi sokungeniswa esishiwo ngejika lokuphulukisa elimise okuka-S (ihamba kancane ngaphambi kwesikhathi, isheshiswe kamuva) namandla okuqalisa abonakala aphezulu; I-Karstedt ayibonisi ukungeniswa, izinga eliphezulu lokuqala eline-exotherm ebukhali, amandla okuvula aphansi.

Ngesikhathi sokucwiliswa, izinhlayiya ze-PTFE endwangu ye-fiberglass zincibilika ngaphezu kuka-327°C, zicekela phansi i-lamellae egoqiwe yoqobo kanye nemingcele yezinhlayiyana ukuze zakhe ukuncibilika kwe-amorphous. Lapho ipholisa, i-PTFE iphinda icwebe ibe ngama-spherulites akhiwe ama-lamellae amise okwe-radially, anobukristalu obusukela ku-50–70%. Izinga lokupholisa linquma ukuphelela kwekristalu: ukupholisa kancane kukhiqiza icrystallinity ephakeme, ama-spherulite amakhulu, ubulukhuni obukhulu; ukucisha ngokushesha kunikeza ama-spherulites amahle kanye nokuguquguquka okuthuthukisiwe.
