Wiremax High voltage PTFE insulated wires manufactured with FEP insulation offer the following:

Fluorinated Ethylene Propylene (FEP) offers an excellent combination of properties that include: exceptional dielectric properties, a low dielectric constant over a wide frequency range, chemical inertness including transformer oils and dielectric fluids, heat resistance with retention of properties after service at 400° F (204° C), toughness, flexibility, possesses a very high degree of stress crackmore resistance, low coefficient of friction, low flammability, negligible moisture absorption, has long term weatherability and excellent resistance to ozone sunlight and weather. FEP offers the lowest refractive index of all thermoplastics with low light reflection (the same as water) less
