Imyenda ya PTFE yubushyuhe bwo hejuru (PTFE isize fiberglass) nibyiza kumukandara utanga ibiryo bitewe nubushyuhe bwa 260 ° C, -70 ° C ubukonje bworoshye, hejuru yinkoni, hamwe no kubahiriza 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 usize PTFE hagati yindorerwamo zindorerwamo zishyushye kuri 360-380 ° C - uhindura cyane morfologiya yubuso, 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, kwiyuhagira hejuru (amazi yimvura yoza umwanda), kohereza urumuri rworoshye (6-13%), Urwego rwumuriro A, nimbaraga zimeze nkicyuma munsi ya 1.5 kg / m². Ikoreshwa muri stade, ibibuga byindege, ninyubako zishushanyije kwisi yose.
