PTFE Materials
PTFE material has very unique heat and chemical resistance. There are many ways of using PTFE for gaskets.
VIRGIN PTFE
PTFE is a soft, low friction fluoropolymer with outstanding chemical resistance and weathering resistance.- White in colour.
- Supplied in rolls: 1220mm wide.
- Thickness: 0.5mm to 10mm (8mm and 10mm only available in sheets).
- Recommended Maximum Temperature: 220°C.
- Recommended Services: Bushings, gaskets, food industry, where good chemical resistance is required.
PTFE ENVELOPES
PTFE envelope gaskets consist of a stable gasket insert and a PTFE envelope. Only high-quality, non-porous PTFE is used for the envelope, to protect the insert against chemical attack.- White in colour.
- Supplied in ‘U’ and ‘V’ shape in sizes as requested.
- Recommended Maximum Temperature: 220°C.
- Recommended Services: Protection against low-cost material gaskets from aggressive chemicals and to protect the
medium against contamination from the gasket material.
