Frequently asked questions (FAQ)

What is PTFE?
Polytetrafluoroethylene (PTFE) is a plastic characterized by an exceptionally low coefficient of friction. It exhibits a high resistance to chemical reactions and boasts a melting point of 327º Celsius, making it suitable for a wide range of applications requiring heat and chemical resistance.
Is a PTFE gasket suitable for highly corrosive materials?
PTFE gaskets offer the advantage of being chemically inert and highly resistant to corrosion, making them virtually impervious to a wide range of acids, alkalis, and corrosive substances in environments up to 260º Celsius. This exceptional resistance significantly reduces the likelihood of chemical degradation or "attack" on the gasket, ensuring reliable performance even in harsh industrial settings.
What types of PFTE gaskets does KLINGER supply ?
KLINGER offers a diverse range of gaskets including: KLINGER®TOP-CHEM 2000, KLINGER®TOP-CHEM 2003, KLINGER SOFT-CHEM, LOAD LOCK, KLINGER®TOP-CHEM 2005, KLINGER®TOP-CHEM 2006, PITA® DNA™, and KLINGER KEMPCHEN PW1A-3.
How are PTFE gaskets made?
In simple terms, PTFE seals undergo a baking process, which requires careful attention. When a block of PTFE is pressed flat, it tends to flow out similar to rubber, which is not ideal for sealing purposes as it loses its shape, rendering it unusable for flange connections. However, by incorporating a filler, the shape of the seal remains intact. This addition significantly reduces the impact of external forces on the deformation of the PTFE material.
