Menene fa'idodin farantin PTFE?
Juriya mai girma- The aiki zafin jiki iya isa 250 ℃.
Low-zazzabi juriya– Yana da kyau inji taurin;ko da yawan zafin jiki ya ragu zuwa -196 ℃, zai iya kula da 5% elongation.
Juriya na lalata- Ba shi da ƙarfi ga yawancin sinadarai da kaushi, kuma yana iya jure wa ƙarfi acid da alkalis, ruwa da sauran kaushi na halitta iri-iri.
Juriya yanayi- Yana da mafi kyawun rayuwar tsufa tsakanin robobi.
Babban lubrication– Mafi ƙasƙanci coefficient na gogayya tsakanin m kayan.
Rashin mannewa- Shi ne mafi ƙanƙanta tashin hankali a tsakanin kayan aiki mai ƙarfi kuma baya bin kowane abu.Matsakaicin juzu'i na kaddarorin inji yana da ƙanƙanta, kawai 1/5 na polyethylene, wanda shine muhimmin fasalin farfajiyar perfluorocarbon.Bugu da ƙari, saboda ƙarfin sarkar fluorine-carbon na intermolecular sun yi ƙasa sosai, PTFE ba ta da ƙarfi.
