PTFE is a subcategory of Fluoroplastics. Its elastic modulus ranges from 150 to 300 MPa. Its flexural modulus ranges from 180 to 260 MPa. Its tensile strength ranges from 4500 to 6000 MPa at break. Its flexural strength ranges from 7400 to 11000 MPa. Its compressive strength ranges from 4600 to 7400 MPa. Its Izod Impact strength ranges from 2.5 to 5 J/cm. Its elongation at break ranges from 80 to 250 %. Its hardness ranges from 75 to 112 Rockwell R. Its specific gravity ranges from 2.08 to 2.2. Its coefficient of thermal expansion ranges from 36 to 70 x 10^-6/°C. Its molding pressure ranges from 1 to 6 MPa.

Fluoroplastics, also known as PTFE, is a thermoplastic polymer. The most common trade name is Teflon. poly(chloro-trifluoro-ethylene) 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.
