Iyi ngingo irasuzuma ingaruka za catalizike ya platine hamwe no kwibanda kuri kinetics yo guhuza-gukiza silicone rubber. Ubwoko bwa catalizike: Cataliste (Acide chloroplatinic, Pt⁴⁺) isaba kugabanuka kubinyabuzima bikora bike-bifite agaciro, bikora nkibisanzwe; Cataliste ya Karstedt (Pt⁰ hamwe na divinyltetramethyldisiloxane) yinjira muburyo bwa catalitiki. Ubwoko bwingaruka: Umuvugizi yerekana igihe cyo kwinjiza hamwe na S-yo gukiza umurongo (buhoro buhoro, byihuta nyuma) nimbaraga zo kugaragara cyane; Karstedt yerekana nta induction, igipimo cyambere cyambere hamwe na exotherm ikarishye, imbaraga zo gukora hasi.

Mugihe cyo gucumura, ibice bya PTFE kumyenda ya fiberglass bishonga hejuru ya 327 ° C, bigasenya umwimerere wafunzwe-urunigi lamellae nimbibi zingana kugirango bibe amorphous. Iyo imaze gukonja, PTFE yongeye kwisubiramo muri spherulite igizwe na lamellae yerekanwe na radiyo, hamwe na kristu ya 50-70%. Igipimo cyo gukonjesha kigena gutunganirwa neza: gukonjesha buhoro bitanga kristu nyinshi, spherulite nini, ubukana bwinshi; kuzimya byihuse bitanga spherulite nziza kandi byoroshye guhinduka.
