Resin Fenolik Cair
Perbedaan utama antara resin fenolik termoplastik (Novolac) dan resin fenolik termosetting (Resol) adalah sebagai berikut:
Perbedaan Struktur
Termoplastik: Struktur linear, larut dan dapat meleleh.
Termosetting: Struktur tiga dimensi (jaringan), membentuk produk yang tidak larut dan tidak dapat meleleh setelah dipanaskan.
Kondisi Sintesis
Termoplastik: Katalis asam, rasio formaldehida/fenol lebih rendah (0,8-0,86:1).
Termosetting: Katalis alkali, formaldehida berlebih (1,1-1,5:1).
Metode Pengerasan
Termoplastik: memerlukan bahan pengeras (misalnya, heksametilenetetramina) untuk penghubungan silang.
Termosetting: mengeras melalui reaksi mandiri gugus hidroksimetil saat dipanaskan.
Aplikasi
Termoplastik: Senyawa cetakan, alat penggilingan, dll.
Termosetting: Bahan tahan api (misalnya, bata magnesia-karbon), produk Bakelite, dll.
