Expanded PTFE (ePTFE) sheets are made from 100% polytetrafluoroethylene through special processes. The internal structure is multi-directional without any fillers, suitable for ultra-pure applications. These microfibers have the same tensile, so numerous pores allow ePTFE to bend arbitrarily. It has a very strong creep resistance and is easy to cut, making it suitable for flange sealing. ePTFE is chemically and abrasion resistant with high and low-temperature resistance, which is suitable for transporting and sealing industrial liquids.
ePTFE Sheet Properties
ePTFE sheets are ideal for sealing gaskets and other applications where flexibility is a top priority. The properties of ePTFE sheets that make them appealing include the following:
|Density||0.85g/cm3 +/- 0.10g/cm3|
|Pressure||200 bar (3000psi)|
|Specific Leakage Rate||2.6 x 10-7|
|Compressibility – ASTM F 36 M||45%|
|Recovery – ASTM F 36M||14%|
In addition, ePTFE is hydrophobic, has a low friction coefficient and is resistant to UV light.
ePTFE Sheet – Applicable Industries
ePTFE sheets are used in many industries. From medical devices to aerospace, these gasket sheets are ideal in almost any situation where high temperatures and chemical resistance static sealing are a consideration.
Our ePTFE sheets hold the following approvals and certifications:
