Product Q&A
Q:What media can expanded PTFE sheet be used to seal?
A:
It is suitable for strong acids, strong alkalis, solvents, hydrocarbons, refrigerants, steam, oxygen, and food-grade media. Due to its chemical inertness, it resists almost all industrial chemicals (except molten alkali metals and high-temperature fluorine gas).
Q:Is this material suitable for food or pharmaceutical applications?
A:
Yes. Expanded PTFE sheet is typically made of pure PTFE without binders or fillers. It complies with FDA 21 CFR 177.1550 and also meets USP Class VI and EU 1935/2004 standards, making it suitable for food processing, pharmaceutical, and drinking water systems.
Q:Is this gasket sheet prone to creep or cold flow?
A:
The micro-fibrous structure of expanded PTFE significantly reduces creep and cold flow tendencies. It exhibits much lower stress relaxation compared to standard PTFE, with minimal thickness loss over long-term service, making it ideal for applications requiring sustained bolt preload.
Q:Can the thickness and size of expanded PTFE sheet be customized?
A:
Yes. Common thicknesses include 0.5 mm, 1.0 mm, 1.5 mm, 2.0 mm, 3.0 mm, etc. It is available in rolls or sheets. We can also cut to gaskets per your drawing or die-cut any shape.
Q:Does installing an expanded PTFE gasket require very high bolt preload?
A:
No. Expanded PTFE sheet offers excellent compressibility and recovery. A tight seal can be achieved with relatively low bolt load, making it especially suitable for brittle flanges (e.g., FRP, plastic, ceramic) or low-pressure, large-diameter equipment.
