1 Ultimate temperature resistance, suitable for high temperatures of batteries and power components
Ultra wide temperature range: PTFE/FEP long-term -65 ℃~+200 ℃, short-term 260 ℃; PVDF can also reach 150 ℃+, far superior to PVC (70 ℃) and XLPE (90 ℃).
Battery thermal environment: During fast charging/high current discharge, the temperature of the battery pack/cell often reaches 120 ℃+, and ordinary insulation is prone to softening and breakdown; Fluoroplastic wires can stabilize insulation and prevent thermal runaway.
Drone/Motor: The electric control, motor, and BMS are continuously at high temperatures, and the fluoroplastic wires' insulation layer does not melt or drip, ensuring the continuous operation of the power system.
2 High insulation+low loss, safe and reliable high voltage and high current
High dielectric strength: resistant to 600V~10kV, insulation resistance ≥ 10 ¹⁸Ω· cm, no leakage or breakdown, suitable for new energy vehicle 300V~800V high-voltage platforms.
High frequency low loss: dielectric constant ≈ 2.1 (stable), minimal loss at high frequencies, efficient signal/power transmission, suitable for high-speed data and power line integration of unmanned aerial vehicles.
Moisture resistant and stable: Water absorption rate<0.01%, insulation does not decrease in humid/condensing environments, outdoor drones and energy storage cabinets are reliable for a long time.
3 Resistant to electrolyte corrosion, battery leads are "non aging and non leakage"
Chemical inertness: PTFE/FEP hardly reacts with electrolyte components such as lithium hexafluorophosphate, carbonate, hydrofluoric acid, etc., and does not swell, crack, or become brittle after long-term contact.
Anti leakage short circuit: When the battery leaks, the fluoroplastic wires' insulation layer continuously blocks the positive and negative electrodes, avoiding corrosion of the copper core and adjacent components, significantly reducing the risk of fire.
Long lifespan: acid and alkali resistant, oil and ozone resistant, maintenance free for 10 years+, suitable for new energy vehicles with a service life of 8 years/150000 kilometers, and drones with a service life of 3-5 years.
4 Flame retardant self extinguishing, the last line of defense against thermal runaway
High oxygen index: PTFE oxygen index ≈ 95%, non combustible, self extinguishing, no dripping, extinguishing immediately upon evacuation of open flames, non combustible, and non spreading flames.
Low smoke and halogen-free: Fluoroplastic wires do not release toxic halogen smoke when burned, reducing secondary damage in case of battery thermal runaway and improving cabin/fuselage safety.
5 Lightweight and thin-walled, unmanned aerial vehicles/electric vehicles reduce weight and improve efficiency
Low density: PTFE ≈ 2.1g/cm ³, 30%~50% lighter than rubber/ordinary plastic; **Thin walled insulation (0.1~0.2mm) * * can further reduce weight.
Small volume and high current: Fluoroplastic wires, with the same current carrying capacity, have a smaller diameter and are softer, making them suitable for small battery pack spaces and compact drone bodies, making them easy to bend and wire.
6 Resistant to vibration/bending, reliable in vehicle operating conditions for unmanned aerial vehicles
Flexibility and fatigue resistance: FEP/PFA has good flexibility, resistance to high-frequency vibration, repeated bending, insulation does not crack under drone takeoff and landing, vehicle bumps, and continuous core wire winding.
Low friction: Smooth surface, easy to pass through pipes during wiring, does not scratch the insulation layer, high assembly efficiency, low failure rate.
Typical application scenarios
Battery lead: Cell module busbar/BMS, resistant to electrolyte, high temperature, and leakage short circuit.
New energy vehicles: high-voltage wiring harness, internal battery pack, motor controller OBC, High voltage safety+thermal stability.
Drone: power line, electric control line, BMS line, signal line, lightweight+high temperature resistance+vibration resistance.
Energy storage/photovoltaics: inverters, energy storage cabinets, photovoltaic wiring harnesses, outdoor weather resistance+flame retardancy+long lifespan.
Fluoroplastic wires, with six core advantages of high temperature resistance, high insulation, corrosion resistance, flame retardancy, lightweight, and vibration resistance, accurately solve the five pain points of "high voltage, high temperature, corrosion, vibration, and safety" in the field of new energy, becoming the preferred insulation material for battery leads and power connections.
