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.
Saint Gobain Tygon® 3350. TYGON® 3350 is an ultra-pure biopharmaceutical-grade tubing that has documented biocompatibility for sensitive appliions. This platinum-cured silicone tubing resists temperature extremes, ozone, radiation, moisture, compression sets, weathering and chemical attack,….
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.
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
Fluoroplastics and Teflon ® materials have many of the same properties however, there are important differences between FEP, PFA, ETFE en PTFE. Click to see. +31 (0)76 - 5718295
Introduction This is 1 meter of PFA tubing with a 6mm diameter. PFA has a high temperature resistance with a melting point of 305C. This tubing is used as a bowden tube in some 3D printer setups.
Silicone Sheet Buy Online. Contact us. Teflon Tubing Buy Online. PPTFE teflon tubing is commonly referred to as Teflon tubing. Teflon refers to three fluoropolymer plastic resins: PTFE, FEP, and PFA. These three plastics share common properties such as lubricity, chemical resistance, high temperature resistance and more.
PFA has significantly improved removal performance compared to 316L stainless steel with a 240 grit finish. See Figure 1. Engineering *The silicone tubing dictates these product specifiions. The working pressure of the PVDF tube adapter connection meets

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) 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
