PTFE vs FEP vs PFA: What’s the difference? - Adtech

The main disadvantage of PFA is that it is more expensive than PTFE and FEP. PFA is ideal for appliions that require a higher purity grade, excellent chemical resistance and a high working temperature. This fluoroplastic is widely used in medical tubing, heat exchangers, semi-conductor baskets, pumps and fittings, and valve liners.

Understanding The Differences Between PFA And PTFE | Tef

30/5/2016· When it comes to tubing, PFA is considered superior to PTFE due to its flexibility. However, PFA has a shorter flex life than PTFE. PFA maintains a transparency under extreme temperatures of up to 500 degree Fahrenheit, while PTFE is milky white up to the same temperature and is also considered more resistant to heat.

What is PFA Tubing? : Holscot Fluoropolymers

17/2/2020· PFA tubing is also resistant to chemicals, even when they sit in the system for prolonged periods of time. The lack of inertness in some chemicals can be destructive to most tubings. PFA tubing is a go-to option for moving elements. Its flexibility and resistance to cracks and breaks make it perfect for moving parts in machinery. PFA Tubing

ETFE Tubing | Fluorotherm

ETFE Tubing. ETFE is a fluoropolymer that is chemically and structurally similar to polyolefins such as polyethylene, thus providing a higher abrasion, impact, and crush resistance than its fully fluorinated (perfluoropolymer) counterparts -PTFE, FEP, and PFA. ETFE tubing is commonly used in wiring harnesses, in exterior film appliions where weathering resistance is desirable, and as a

Expanded PTFE (ePTFE) vs PTFE: What’s the difference?

Expanded PTFE (ePTFE) tube is microporous so air-permeable, and is perfect for any appliions that require a permeable material. As such, ePTFE is different to conventional PTFE. The material is soft and flexible, and feels somewhat like smooth, spongey marshmallow to the touch. Expanded PTFE is often used in the form of cord, sealing tape or
