PTFE gaskets
PTFE gaskets have great resistance to most mineral and organic chemicals such as acids, bases, and solvents, and can be used up to approximately 240°C. The teflon gaskets are good for use with petrol & oils and excellent choice for use with acids and alkalis.
The gaskets of PTFE have good ozone resitance and good impermeability to gases. The PTFE raw material for the gaskets has probably the best possible friction coefficient.
PTFE gaskets are generally used in the presence of aggressive chemicals. The PTFE gasket can be designed as a bore liner to shield pipe gaskets from the chemical attack. These are supplied to fit the bore size, and are known as PTFE envelopes.
Is PTFE gasket the Best option for My Application? If you are unsure as to which material is best for your application then you can consult our gasket material selector. Material specifications of the PTFE material can be downloaded from the PTFE sheets section in the Engineering Plastics part of the site.
We can cut your PTFE gaskets by request, exactly as per your specification. Both certification and traceable certification can be supplied with your PTFE gaskets, should it be required by you or your customer. Traceable certification for the PTFE gaskets cannot be retrospectively supplied on orders that have already been fulfilled.
PTFE gaskets
PTFE gaskets PTFE, Unfilled Teflon® Gaskets (Virgin Teflon® Gaskets) Virgin grade PTFE (Teflon®) gaskets are made from 100% pure material which is used in most general applications. It is extremely soft and formable and is often used for chemical resistant seals and gaskets. It is made directly from the resin producer and has never been processed into a shape. It possesses the highest physical and electrical insulation properties and has increased resista..
PTFE еnvelope gaskets
PTFE envelope gaskets are assembled and closed in an envelope of 100% pure PTFE and are used as seals on flanges, tanks, reactors and enamelled or vitrified surfaces. These gaskets can be produced in various shapes: ovals, circular, custom-made drawing, with corrugated ring and earth clips made of AISI 316 steel.PTFE envelope gaskets combine the low friction and chemical stability of PTFE with the mechanical strength of the gasket material. This provides the user with a..
What are the chemical resistance properties of PTFE gaskets?
PTFE gaskets exhibit exceptional resistance to a wide range of mineral and organic chemicals, including acids, bases, and solvents. They can withstand exposure to aggressive media and maintain their integrity, making them suitable for various industrial applications.
At what temperatures can PTFE gaskets be effectively utilized?
PTFE gaskets can be used effectively in applications with temperatures up to approximately 240°C. This thermal stability allows them to function well in high-temperature environments, ensuring reliable sealing performance.
What are the advantages of using PTFE envelope gaskets over standard PTFE gaskets?
PTFE envelope gaskets combine the excellent chemical resistance of PTFE with the enhanced sealing properties of other materials. This design provides improved sealing capabilities, particularly in applications where conventional gaskets may fail due to pressure fluctuations or temperature variations.
