Edemede a na-enyocha mmetụta nke ụdị platinum catalyst na itinye uche na crosslinking kinetics nke mgbakwunye silicone roba. Ụdị ihe na-akpata: Speier catalyst (chloroplatinic acid, Pt⁴⁺) chọrọ mbelata na ụdị ndị dị ala na-arụ ọrụ, na-arụ ọrụ dị ka precatalyst; Karstedt catalyst (Pt⁰ nwere divinyltetramethyldisiloxane) na-abanye ozugbo na okirikiri catalytic. Mmetụta ụdịdị: Speier na-egosi oge nnabata akpọpụtara ya na usoro ọgwụgwọ ụdị S (dị nwayọ ngwa ngwa, emechara ngwa ngwa) yana ike ịgbalite pụtara elu; Karstedt egosighi nnabata, ọnụego mmalite dị elu na exotherm dị nkọ, ike ịgbalite obere.

N'oge sintering, PTFE ahụ na fiberglass ákwà agbaze n'elu 327°C, na-ebibi mbụ apịaji-chain lamellae na urughuru ókè na-etolite amorphous gbazee. Mgbe jụrụ oyi, PTFE recrystallizes n'ime spherulites nke mejupụtara radially gbakwasara lamellae, na crystallinity sitere na 50-70%. Ọnụego jụrụ oyi na-ekpebi izu oke kristal: ngwa ngwa jụrụ oyi na-eme ka kristal dị elu, spherulites buru ibu, ike siri ike; Nkwụsị ngwa ngwa na-enye spherulites dị mma yana ime mgbanwe dị mma.
