Short for fluorinated ethylene propylene, FEP cable has many applications, and there are several advantages associated with using FEP cable over other types of cable. Let’s take a look at some of these uses and benefits in further detail, specifically examining why FEP may be equivalent, or even superior, to Polytetrafluoroethylene (PTFE).<\/p>\n
Advantage #1 of FEP Cable – Fluorinated ethylene propylene’s corrosion resistance is exactly on par with PTFE’s. As a result, it stands up to caustic agents in the same way. Its pure carbon-fluorine structure and its fluorination enable it to resist corrosive situations. In particular, FEP coated cable withstands exposure to detergents far better than PTFE does.<\/p>\n
Advantage #2 of FEP Cable – Fluorinated ethylene propylene has a lower melting point than other cable materials like PTFE and PFA. The exact point hovers at around 260\u00b0C (500\u00b0F).<\/p>\n
Advantage #3 of FEP Cable – Electrically speaking, only PFA outdoes fluorinated ethylene propylene. That means the material has one of the highest dielectric strengths available. At the same time, FEP dissipates at a rate that is six times that of PFA. The end result is that FEP better conducts electrostatic fields non-linearly.<\/p>\n
Advantage #4 of FEP Cable – In terms of its flexibility, fluorinated ethylene propylene holds a slight edge over PTFE, giving it a small leg up in the mechanical department.<\/p>\n
Advantage #5 of FEP Cable – When cable leads are made of FEP, they exhibit outstanding chemical, fluid, age and ozone resistance.<\/p>\n
Advantage #6 of FEP Cable – Fluorinated ethylene propylene allows for a smaller diameter.<\/p>\n
Advantage #7 of FEP Cable – When a torque-free design is incorporated into the cable, the memory that is typically found in right hand or left hand twisted cables is eliminated.<\/p>\n
As might be imagined it is precisely this cable’s benefits that render it ideal for certain applications. Some of these situations include:<\/p>\n
Application #1 for FEP Film\/Cable: Wiring – Think wire used for hookup, coaxial cables, computer wiring, and technical gear wiring.<\/p>\n
Application #2 for FEP Film\/Cable: Aerospace – In this application, fluorinated ethylene propylene film helps protect molds during the curing process.<\/p>\n
Application #3 for FEP Film\/Cable: Labware and Tubing – The highly corrosive chemical processes that often occur in the lab can do a number on plastic labware and tubing. FEP provides excellent resistance against such attacks.<\/p>\n
Application #4 for FEP Film\/Cable: Industrial High Temperature Applications (e.g., glass plants, boiler locations, chemical processing plants, areas close to steam lines) – When multiple conductor cables are insulated and jacketed with fluorinated ethylene propylene, resistance to abrasion and mechanical abuse reaches a maximum. Moisture and fluid damage is also mitigated.<\/p>\n
Dupont, the manufacturer of FEP, also lists these applications for the product:<\/p>\n
