GASKET SHEET TOP CHEM 2000
Universal heavy-duty gasket, which offers an exceptional performance in applications with high mechanical requirements at high temperatures. The only PTFE gasket with a Fire-safe-certificate. Jest to też materiał znajdujący zastosowanie w przemyśle spożywczym, farmaceutycznym, dla pary i w instalacjach z tlenem oraz tam, gdzie występują specjalne wymagania dotyczące szczelności według TA-Luft.
KLINGER® Top-Chem 2000 features superior chemical resistance to strong acids and bases and offers excellent performance in applications with high mechanical demands at high temperatures.
Areas of application:
In the first area, the gasket material is suitable for use provided that it has adequate chemical resistance to the medium.
In area two, the gasket material may prove applicable, but additional calculations are recommended.
In area three, additional calculations are required prior to installation of the gasket.
