Frequently Asked Questions about PTFE Gaskets
Is PTFE a food-safe gasket material?
Yes, Virgin PTFE (Pure Teflon) is completely food-grade and non-toxic. It is FDA-approved, non-reactive with food, and easy to clean, making it ideal for food manufacturing plants and pharmaceutical equipment.
Can PTFE gaskets withstand very hot temperatures?
Absolutely. PTFE gaskets are known for their exceptional thermal stability, reliably operating in service temperatures up to +260∘C (and short-term maximums up to 300∘C), making them a top choice for high-heat environments.
What is the benefit of using Filled PTFE grades (Carbon, Glass, Bronze)?
Adding fillers significantly enhances the PTFE’s mechanical properties, increasing creep resistance, compressive strength, and wear resistance. This makes them better suited for high-load, high-pressure, and abrasive industrial applications where pure PTFE might deform over time.
Do you offer custom-made PTFE gaskets?
Yes. We specialize in custom fabrication and can produce PTFE gaskets in any size, shape, or specification (including specialized cuts for irregular flanges or proprietary equipment) using our advanced CNC machinery.
