Product Description
PTFE Thread Seal Tape
also known as sealing tape, stop with the tape. Is a PTFE dispersion resin paste pasting, rolling from the tape without any additives products. White, smooth surface, uniform texture, with excellent heat resistance, corrosion resistance, and self-adhesive, good fit, have a good seal. Can be widely used in pure oxygen, gas, strong oxidants, corrosive media and high temperature steam pipeline thread sealing and pump, valve, equipment, complex shape of the filling seal.
APPLICATION
PTFE Thread Seal Tape has a good toughness, vertical strength, easy to deform transverse features.
It is more ideal for sealing plates and threads. However, it can not be used in contact with high concentrations of oxygen or liquid oxygen.
Expanded PTFE tape is mainly used for more disk and thread port seal.

FAQ
1.Q: How to distinguish pure PTFE from filled PTFE sheets?
A: Pure PTFE is white without additives (labeled "Virgin PTFE"); filled types specify additives and may appear gray/off-white.
2. Q: Are the products certified with international standards ?
A: Pure PTFE complies with FDA . Filled types depend on formulations.
3. Q: Can I request samples?
A: Free 20×20cm samples are provided (shipping cost paid by buyer).
4. Q: What is the lead time for custom sizes/thickness?
A: Standard sizes ship in 7 days; custom orders take 15-30 days (based on complexity).
5. Q: How to verify chemical resistance data?
A: Third-party test reports.
6. Q: What is the packaging ?
A: With wooden crates, suitable for sea/air freight.
7. Q: Will harmful substances be released ?
A: Pure PTFE is stable up to 250ºC; filled types require additive verification.
8. Q: Can you deburr sheet edges or provide precision machining?
A: Standard sheets are rough-cut; CNC finishing (±0.1mm tolerance) is available at additional cost.
9. Q: What if the product fails performance tests after delivery?
A: Disputes within 15 days require third-party test reports. Confirmed issues trigger free replacement or refund.
