四氟銅粉墊片-PTFE back up rings

PTFE provides excellent resistance to an exceptionally wide range of aggressive substances. Additionally it is chemically inert, increasing its suitability for applications sensitive to external contamination.

PTFE Sheeting to BS 3784 is available in thicknesses from 0.5mm to 50mm and in a number of sheet sizes:

1500mm x 1500mm, 1200mm x 1200mm, & 600mm x 600mm.

PTFE offers the following characteristics:

• Low Friction
• Good Electrical Insulation
• Wide Temperature Range (from 260º+ to -200º)
• Acid & Chemical Resistant

Chemically or mechanically etched sheet and strip is available where bonding to other components or structures is required. Thinner gauge sheeting is also available.

We have access to Extended and Moulded PTFE Rod and Tube. Whatever the application we can supply an efficient solution to meet your requirements.

Virgin PTFE grades are used for Gaskets in the food & pharmaceutical industries. Expanded PTFE grades are used for damaged flange faces and glass or plastic flanges and Filled PTFE grades are used where specific physical or electrical properties are required.

Standard Rubber joints can be provided with an envelope of pure PTFE to protect the exposed joint edge from corrosive attack, or for applications where hygiene conditions are essential. In addition we stock a wide range of PTFE envelopes to suit standard pipe flanges and special envelopes can be fabricated to almost any given size or insert.
