PTFE Envelope Gasket
PTFE Envelope Gaskets are the ideal solution for applications demanding virtually 100% chemical resistance
Description:PTFE Envelope Gasket consists of rubber-asbestos, non-asbestos, rubber, corrugated stainless steel etc. cushion material encased in PTFE envelope, resulting in a gasket with the excellent corrosion resistance of PTFE and the strength and resilience of core material. It can be produced in several types to meet the most demanding applications.
V type, Slit in center from outside, An economical solution for lower pressure applications.
L type, Cut PTFE into square form, For use with medium and higher pressure.
U type, Heated & welded at one joint, Normal for DN≥200mm.
APPLICATION & PROPERTIES:
PTFE Envelope Gaskets are the ideal solution for applications demanding virtually 100% chemical resistance and where the mechanical properties of a compressed gasket material are also needed. They perform well in the food and process industries where contamination of the medium cannot be permitted, Suitable for medium strong alkalis, cryogenic fluids, oxygen, chlorine gas etc.

Teflon PTFE Envelope Gaskets
Gaskets are an integral part of piping systems and their fittings. In corrosive environments the reliability of gaskets is of utmost importance, where gasket failure can have detrimental effects leading to system failure.
Tetron S, which is Dotmar's trade name for virgin PTFE (polytetrafluoroethylene) is resistant to virtually all chemicals and has excellent non-stick properties. The material also operates within a wide temperature range and is capable of continuous use at 260? thus making it the ideal material for the envelope gaskets.
Dotmar EPP are suppliers and stockists of an extensive range of envelope gaskets. The IBC envelope gaskets are manufactured to British standards with nominal bores ranging from 15mm to 600mm. Customised requests are also welcome and further enquiries can be made at any one of our branches throughout Australia.
