Wire and Cable Jacketing PTFE is a subcategory of Fluoroplastics. It is specially formulated to wire and cable jacketing. Its elastic modulus ranges from 145 to 190 MPa. Its flexural modulus ranges from 145 to 260 MPa. Its flexural strength ranges from 7000 to 8600 MPa. Its compressive strength ranges from 6600 to 7100 MPa. Its elongation at break ranges from 300 to 500 %. Its specific gravity ranges from 1.76 to 1.77. Its coefficient of thermal expansion ranges from 121 to 140 x 10^-6/°C. Its melting temperature ranges from -30 to -20 °C.

Fluoroplastics, also known as PTFE, is a thermoplastic polymer. The most common trade name is Teflon. poly(vinylidene fluoride) It has low mechanical strength and is expensive. It has very low coefficient of friction. PTFE is commonly used in applications needing excellent dielectric strength and chemical and temperature resistance.
