PTFE Sheets

Inert sheet stock for the worst media

Virgin and filled PTFE sheet for cutting chemically inert gaskets, linings and machined parts that resist almost any process fluid.

Chemically inert across virtually the entire pH range
Filled grades add creep resistance and load capacity
Skives and machines cleanly to tight tolerance
FDA and USP Class VI grades for purity-critical duty
Very low friction for slide plates and wear surfaces

Temperature: -200°C to +260°C
Pressure: Up to 80 bar (filled gasket duty)
pH range: 0 – 14

In ServiceUSE

Where it holds the line

PTFE sheet is the go-to stock when nothing else survives the chemistry. Virgin grades are inert across the full pH range and ideal for high-purity gaskets and slide surfaces, while glass-, carbon- and bronze-filled grades add the creep resistance and load capacity that machined seats and wear pads demand. Skived or moulded, the sheet cuts and machines cleanly into gaskets, diaphragms, linings and bushings that shrug off acids, solvents and oxidisers alike.

Typical applications

01Chemically inert cut gaskets and seats
02Reactor and vessel linings
03Diaphragms and slide / wear plates
04Machined bushings and back-up rings
05High-purity and food-contact parts
