Imyenda yubushyuhe bwo hejuru ya PTFE (fiberglass ya PTFE) ni nziza kumukandara utanga ibiryo kubera ubushyuhe bwayo 260 ° C, -70 ° C ubukonje bukabije, ubuso butari inkoni, hamwe na FDA. Ibyingenzi byingenzi: amashyiga yimigati (ibisuguti, umutsima, pizza), ibyokurya bikaranze, imirongo ikonjesha bombo, tunel ikonjesha, ibyuma bifata ubushyuhe, hamwe no kuzinga. Kugabanya imyanda nigihe cyo gukora isuku.

Calendering - gukanda umwenda ushyizweho na PTFE hagati yindorerwamo zishyushye zishyushye kuri 360-380 ° C - uhindura kuburyo bugaragara imiterere yimiterere, kurekura ibintu, kudahinduka, hamwe nubukanishi. Igabanya ubukana kuva kuri Ra 0.5-1.0 mkm kugeza kuri <0,05 mm, ifunga pinholes, itezimbere imyambarire, ariko igabanya imbaraga zamarira no guhinduka. Ibyingenzi kurekura imirongo hamwe no gukwirakwiza amashanyarazi.

Imyenda ya PTFE yubushyuhe bwo hejuru (PTFE membrane material) ni ihitamo ryiza kubwubatsi bubi. Ibyiza byingenzi: ubuzima bwimyaka 30+ yo hanze, kwisukura hejuru (amazi yimvura yoza umwanda), kohereza urumuri rworoshye (6-13%), Urwego rwumuriro A, nimbaraga zisa nicyuma munsi ya 1.5 kg / m². Ikoreshwa muri stade, ibibuga byindege, ninyubako zishushanyije kwisi yose.
