Hello everyone, Zhejiang IRONFLON is a supplier and manufacturer of fluororesin insulated wires. We have worked with many domestic and foreign customers, and the most frequently asked is FEP Wire (F46 fluoroplastic wire). Below, based on the company's experience, we will talk about this wire to help procurement and engineers choose.
FEP, also known as Fluorinated Ethylene Propylene (FEP) copolymer, commonly known as F46 in the industry, is a thermoplastic material that can be melted and processed. The high temperature wire used as an insulation layer is FEP Wire, and common models include UL1332 and UL1330.
Advantages of FEP insulated wire: crushing ordinary PVC and silicone wires
high and low temperature resistance
Ordinary silicone wires will accelerate aging in an environment of 180 ℃, while PVC insulated wires will quickly melt and deform in an environment exceeding 100 ℃; FEP will not break at temperatures as low as minus tens of degrees Celsius, and can continue to work in environments close to 200 ℃ inside ovens and heating equipment. The insulation layer will not soften or shrink. Many oven and thermoforming equipment manufacturers we have worked with have reported that the lifespan of FEP insulated wire is about three times that of other ordinary wires.
High frequency signal with zero attenuation
Whether it is RF instruments, 5G test cables, semiconductor testing equipment, or internal wiring of medical imaging, they all require extremely high signal stability. FEP has extremely low dielectric loss, and there will be no signal distortion or excessive attenuation during high-frequency transmission.
Comprehensive anti-corrosion and moisture-proof measures
Chemical equipment, electroplating workshops, and outdoor equipment on the sea are filled with corrosive mist in the air, and ordinary wires break their skin and leak electricity within six months. FEP has extremely strong chemical inertness and does not react with the vast majority of liquids and gases. It will not crack or age due to long-term outdoor exposure to sunlight or ozone, and does not require additional protective sheaths, simplifying the wiring structure.
Easy processing and wiring, worry free construction
Compared to PTFE, which requires sintering molding, FEP has a mature melt extrusion process and can be used for ultra-thin wall insulation. Under the same wire gauge, the outer diameter of the cable is smaller, and it is easier to thread in narrow equipment cavities; The insulation surface is smooth, and multiple wire harnesses bundled together will not wear each other out. The insulation layer is intact after thousands of repeated bending tests, making it the preferred choice for motion wire harnesses in automation equipment.
cost-effective
Many customers ask about PFA cables as soon as they come up, and their budget directly exceeds the limit. In the vast majority of conventional high temperature scenarios below 200 ℃, FEP can completely replace PFA with minimal performance difference, lower procurement costs, sufficient stock in stock, and no need for long-term production scheduling. Small and medium-sized foreign trade orders and production equipment are more cost-effective.
Application scenarios of FEP insulated wire
Precision Electronics and Instruments
Oscilloscope, detection equipment, internal connection wires of sensors, UL1332 standard machine wires, multi-color thin-walled FEP insulated wires, compact space and neat wiring;
Aerospace and Rail Transit
Internal wiring in the cabin, aircraft inspection wiring harness, high-speed rail high-temperature control cabinet wiring, flame retardant and low smoke, meeting strict safety standards;
Semiconductors, photovoltaic new energy
High temperature wiring inside photovoltaic inverters, chip testing equipment, and coating machines, clean and free of precipitation, and do not contaminate precision components;
medical equipment
The internal circuits of high-temperature sterilization equipment and the RF wires of imaging equipment are corrosion-resistant, non-toxic, and low smoke, meeting the requirements of medical cleanliness;
Industrial heating and automation equipment
Industrial ovens, injection heating coils, high-temperature fans, and robot motion wiring harnesses are not easily damaged by long-term high-temperature bending;
Chemical and outdoor special equipment
Electroplating equipment, marine monitoring instruments, outdoor high-temperature lighting wires, acid and alkali resistant, UV resistant, and have not aged for many years outdoors.
Attention to detail when choosing FEP insulated wire
Based on our factory's years of production and customer experience, we would like to offer you several practical purchasing suggestions:
- Identify UL certified models: UL1332 is selected for regular 300V, UL1330 is selected for high voltage conditions (600V), insulation purity of uncertified wires is insufficient, and high temperature is prone to leakage;
- Conductor selection as needed: Tin plated copper is sufficient for ordinary equipment, while silver plated copper is preferred for high-frequency RF and aviation equipment, with stronger conductivity and oxidation resistance;
- Distinguish between thin-walled and standard wall thickness: Choose thin-walled FEP for narrow equipment cavities, and thicker insulation for equipment with high vibration and friction to improve wear resistance and lifespan;
- The purity of the material is crucial: low-priced recycled FEP contains many impurities, and high temperatures can release harmful substances, resulting in a significant decrease in insulation strength. Long term use poses a risk of short circuits; Zhejiang IRONFLON uses all new imported fluoroplastic particles, and material testing reports can be provided for each batch. All foreign trade export orders meet the environmental standards of various countries.
FEP insulated wire, as a star product in fluoroplastic wires, balances temperature resistance, electrical performance, processing difficulty, and procurement costs, and is currently the most widely used high temperature wire in the market. We have year-round stock of full specification FEP wires from Zhejiang IRONFLON. We have sufficient inventory of 10AWG-30AWG standard wire, with multiple colors available in red, black, yellow, blue, white, and green. Our products are exported to multiple countries around the world, and we can communicate with anyone who has purchasing needs at any time.
