Ichi chinyorwa chinoongorora pesvedzero yeplatinamu catalyst mhando uye kutarisisa pane crosslinking kinetics yekuwedzera-kurapa silicone rubha. Catalyst types: Speier catalyst (chloroplatinic acid, Pt⁴⁺) inoda kuderedzwa kune inoshanda yakaderera-valent marudzi, inoshanda se precatalyst; Karstedt catalyst (Pt⁰ ine divinyltetramethyldisiloxane) inopinda zvakananga catalytic cycle. Mhando mhedzisiro: Speier inoratidza yakadudzwa induction nguva ine S-yakaita kurapa curve (inononoka kare, inomhanyisa gare gare) uye yakakwirira inooneka activation simba; Karstedt inoratidza hapana induction, yakakwirira yekutanga mwero ine inopinza exotherm, yakaderera activation simba.

Panguva yekunyunguduka, PTFE zvimedu pajira refiberglass zvinonyunguduka pamusoro pe327°C, zvichiparadza cheni yakapetwa-cheni lamellae uye miganhu kuti iite amorphous kunyungudika. Pakutonhora, PTFE inodzokorora kuita spherulites inoumbwa neradially oriented lamellae, ine crystallinity inotangira 50-70%. Chiyero chekutonhora chinogadzirisa kukwana kwekristaro: kunonoka kutonhora kunobereka crystallinity yakakwirira, spherulites yakakura, kuoma kukuru; kukurumidza kudzima kunopa yakanakisa spherulites uye yakagadziridzwa kuchinjika.
