Ptfe Envelope Gaskets

We Are Ptfe Envelope Gaskets Manufacturer & Supplier in India. PTFE envelope gaskets are made and sealed in an envelope of 100% pure PTFE and utilized as seals on flanges, tanks, reactors, and enamelled or vitrified surfaces. These gaskets are available in a variety of forms, including ovals, circulars, and bespoke drawings, as well as corrugated rings and earth clips made of AISI 316 steel.

PTFE envelope gaskets combine PTFE's low friction and chemical stability with its mechanical robustness. This gives the user a gasket that can be safely used with aggressive media that would damage many other materials. We can offer PTFE envelope gaskets for various flange types and sizes.

Elements that make up the envelope gaskets :

    PTFE envelopes the sheath, commonly known as “envelope”, is produced using excellent quality pure PTFE with a thickness of 0.5 mm. The PTFE makes the envelope gasket suitable for use in the chemical, pharmaceutical and food industries thanks to its excellent physical-mechanical characteristics that can be summarised as follows:

  • Excellent Resistance to Acids Which Protects the Inserts
  • Can Come into Contact with Foodstuffs
  • Does Not Leave Residue on the Surface of the Flanges, Enabling Fast Replacement
  • Resists Sudden Changes of Temperature .
  • Excellent Dielectric Characteristics
  • Low Level Porosity

    • The envelope can be of different types according to the application and the customer’s requirements. In the case of small quantities of large Envelope gasket inserts.

Advantages :

  • Excellent resistance to almost all chemicals
  • No Chemical Leaching
  • Exceptional flexibility & uniting the flexibility of an elastomer w/ the chemical resistance of PTFE
  • Excellent Temperature Range
  • Excellent Cleanability due to PTFE (Teflon) Envelope

People also ask

  • What is the material used to make PTFE envelope gaskets?
  • PTFE envelope gaskets are made and sealed in an envelope of 100% pure PTFE.
  • What are the forms in which PTFE envelope gaskets are available?
  • PTFE envelope gaskets are available in various forms, including ovals, circulars, and bespoke drawings, as well as corrugated rings and earth clips made of AISI 316 steel.
  • What are the benefits of using PTFE envelope gaskets?
  • PTFE envelope gaskets combine PTFE's low friction and chemical stability with its mechanical robustness, making them suitable for use with aggressive media that would damage many other materials.
  • How thick is a PTFE envelope gasket?
  • The PTFE envelopes are open onto the outer or inner diameter, or encase the entire insert, depending on what is required. The envelope is 0.5 mm thick and therefore very stable. Lathed envelopes can be produced with an internal Diameter 2 to 4 mm thicker to provide greater diffusion sealing.
  • Is PTFE moisture resistant?
  • Very high melting point: With a melting point of around 327°C, there are very few situations where PTFE would be damaged by heat. Hydrophobic: It's resistance to water means it never gets wet, making it useful in cooking, wound dressings and more.
