Likarolo tsa PTFE
● Ho hanyetsa mocheso o phahameng
Mocheso oa eona oa ho sebetsa o ka fihla ho 250 ℃.
● Ho hanyetsa mocheso o tlaase
E na le boima bo botle ba mochini mocheso o tlase;le haeba mocheso o theohela ho -196 ℃, o ka boloka bolelele ba 5%.
● Ho hanyetsa ho bola
Ha e na matla ho lik'hemik'hale le lihlapolli tse ngata, 'me e khona ho hanela li-acid tse matla le alkalis, metsi le lihlapolli tse fapaneng tsa tlhaho.
● Ho hanyetsa boemo ba leholimo bo botle
