He article hian addition-cure silicone rubber crosslinking kinetics-a platinum catalyst type leh concentration-in nghawng a neih dan a zirchiang a ni. Catalyst chi hrang hrang: Speier catalyst (chloroplatinic acid, Pt4+) hian active low-valent species-ah tihtlem a ngai a, precatalyst angin a thawk a; Karstedt catalyst (Pt0 leh divinyltetramethyldisiloxane) chu direct in catalytic cycle ah a lut a. Type effects: Speier hian induction period langsar tak a nei a, S-shaped curing curve (slow early, accelerated later) leh apparent activation energy sang zawk a nei a; Karstedt hian induction a nei lo a, initial rate sang tak a nei a, sharp exotherm a nei a, activation energy a hniam zawk bawk.

Sintering lai hian fiberglass fabric-a PTFE particle te chu 327°C aia sangah an melt a, original folded-chain lamellae leh particle boundary te chu a tichhia a, amorphous melt a siam a ni. A lum chuan PTFE chu radially oriented lamellae atanga siam spherulites ah a recrystallize leh a, crystallinity chu 50–70% inkar a ni. Cooling rate hian crystal perfection a tichiang a: slow cooling hian crystallinity sang zawk, spherulites lian zawk, hardness sang zawk a pe chhuak a; rapid quenching hian spherulites finer a pe a, flexibility a ti tha zawk bawk.
