What is FEP insulation?
Typically referred to as FEP, Fluorinated Ethylene Propylene is a type of fluoropolymer commonly extruded as both an insulation and jacket material for wire and cable. FEP exhibits outstanding resistance to chemicals, has a wide temperature range and excellent electrical properties.
What is FEP used for?
FEP (fluorinated ethylene propylene) is a tough, flexible copolymer of tetrafluoroethylene and hexafluoropropylene. It is often used for flexible tubing and fluid processing equipment when chemical resistance, high purity, and low stiffness are required. FEP has outstanding electrical properties and UV resistance.
How is FEP made?
Production. FEP is produced by free-radical polymerization of mixtures of tetrafluoroethylene and hexafluoropropylene. The mixture is biased to compensate for the relatively low reactivity of the propylene component. The process is typically initiated with peroxydisulfate, which homolyzes to generate sulfate radicals.
Which is better PFA or PTFE?
PFA is superior to PTFE in terms of flexibility particularly when it comes to tubing applications. PTFE is slightly more resistant to heat than PFA. PFA is more affected by water absorption and weathering but is superior to PTFE when it comes to salt spray resistance.
Is FEP a polyolefin?
One advantage of FEP is that it is completely transparent (as opposed to the pre-existing ‘clear’ coloured polyolefin heatshrink which is actually has a more translucent finish). The main benefit of FEP however is that grease and dirt will not adhere to this material.
What is XLPE insulation?
Cross-linked Polyethylene, also referred to as XLPE, is a form of insulation that is created through both heat and high pressure. The most important attribute of XLPE is the electrical properties it exhibits. A cable with XLPE insulation is able to carry large currents and high voltages.
What is TFE insulation?
Tetrafluoroetheylene, also referred to as TFE, is a synthetic fluoropolymer more commonly known as Teflon®. Teflon® is the broader material while FEP, PTFE, and ETFE are subsets of Teflon®. TFE can withstand very high and low temperatures, is extremely durable and exhibits excellent electrical properties.
What is FEP in education?
A designation that means a student is no longer considered as part of a school’s English learner (EL) population.
What is the chemical name for FEP?
Iron phosphide
Iron phosphide (FeP) | FeP – PubChem.
Why is PFA so expensive?
However, when compared with other resins, they are significantly more expensive and require special techniques to injection mold due to their shear sensitivity, high melt temperatures, and fluorine outgassing when melted. Its melting point of 260 °C (500 °F) is about 40 degrees lower than PFA’s.
What material is PFA?
PFA (perfluoroalkoxy) is a tough, flexible fluoropolymer that is used for flexible tubing and fluid processing equipment when chemical resistance, high purity, and low stiffness are required.
What can FEP insulated wire be used for?
FEP insulated wire is commonly used in chemical, electrical, and medical applications and maintains its properties in temperatures ranging from -200° C to +200° C (or -328° F to +392° F). Dacon Systems can use FEP to custom manufacture thin wall wire insulation and heavy wall wire insulation and cable jackets to your specifications.
What’s the difference between PFA and FEP insulation?
PFA insulation can withstand operating temperatures up to 260° Celsius, and has superior mechanical strength at high temperatures as compared to FEP insulation. It exhibits excellent low-temperature toughness.
What kind of applications can FEP be used for?
FEP exhibits outstanding resistance to chemicals, has a wide temperature range and excellent electrical properties. Due to these physical and electrical characteristics, FEP is a popular choice for use in numerous industries, including aerospace, medical, lighting, and electronic applications.
Which is better for high temperature cable PFA or FEP?
PFA Insulated Cable and Wire is excellent for high temperature applications. PFA insulation can withstand operating temperatures up to 260° Celsius, and has superior mechanical strength at high temperatures as compared to FEP insulation. It exhibits excellent low-temperature toughness.
