PTFE is the classic, original, and gold standard of fluoropolymer tubing. PTFE was the "miracle" fluoropolymer invented in the 1940's by DuPont - a product originally without a market and hard to process. Most other materials continue to use PTFE as a reference for chemical resistance.
The unique properties of PTFE tubing cover an impressive range. These include high use temperature compared to other polymers, almost universal chemical resistance, excellent electrical properties at high voltage and high signal frequencies, non-stick characteristics, usefulness under extreme low temperatures (cryogenic conditions), and UV resistance. However, mechanical strength and wear resistance are not criteria for which PTFE is recommended, which is one reason for the development of FEP tubing, PFA tubing and ETFE tubing.
PTFE tubing's high viscosity in the gel state (it does not truly melt) prevents it from being processed conventionally in extruders or injection molding. PTFE tubing is therefore dry molded or extruded in hydraulic extruders with (paste extrusion) or without (ram extrusion) lubricants. Paste extrusion of PTFE yields flexible tubing. However, it occurs in a batch process and thus long continuous lengths are limited to the batch size, unlike the melt-processible fluoropolymers FEP, PFA and ETFE.
Key Properties:
- The original Teflon(R) fluoropolymer
- The gold standard for inertness to the largest range of chemicals
- Lowest coefficient of friction of any polymer
- Great in a wide range of applications from electrical wire insulators, fluid flow tubing, medical devices, automotive, and hot and cryogenic (-320 F) uses.
- Excellent electrical properties - breakdown voltage and dielectric constant
- High use temperature range of 500 degrees F (260 degrees C)
- Excellent UV resistance and weatherability

FAQ:
Q: Are you manufacturer or trading company?
A: we are manufacturer.
Q: How to get the quickest quotation?
A: send e-mail with drawing directly.
Q: How to get quotation without drawing?
A: possible send sample, pictures or detail descriptions of products to us, we will return you drawing for confirm.
Q: I have an idea for a new product, but not sure if it can be manufactured. Can you help?A. Yes! We are always happy to work with potential customers to evaluate the technical feasibility of your idea or design and we can advise on materials, tooling and likely set-up costs.
Q: My custom products have already been developed on CAD. Can you use the drawings?
A. Yes! DWG, DXF, IGES, Solidworks and Rhino files can all be used to generate quotes, models and mould tools - this can save time and money in producing your parts.
Q: Can I test my idea/product before committing to mould tool manufacture?
A. Yes, we can use CAD drawings to make models for design and functional evaluations.
Q: What type of plastic material is best for my design/product?
A. Materials selection depends on the application of your design and the environment in which it will function. We will be happy to discuss the alternatives and suggest the best material.
Q: How about sample?
A: free sample is available for your quality evaluation, but you should pay the freight. Regarding customize products, sample and mould order will go first before mass production.
