PTFE is a subcategory of Fluoroplastics. Its flexural modulus ranges from 95 to 120 MPa. Its tensile strength ranges from 4000 to 4300 MPa at break. Its specific gravity ranges from 2.12 to 2.17. Its coefficient of thermal expansion ranges from 140 to 210 x 10-6/°C. Its melting temperature ranges from 300 to 310 °C. Its molding pressure ranges from 3 to 20 MPa.
Fluoroplastics, also known as PTFE, is a thermoplastic polymer. The most common trade name is Teflon. perfluoro-alkoxyalkane (PFA) 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.
Other common Fluoroplastics (PTFE) include PTFE, Granular PTFE, 25% Glass Fiber Reinforced PTFE, Unfilled PTFE, 20% Milled Glass Fiber PTFE, Unfilled Film PTFE, Filled Film PTFE, Molding and Extrusion PTFE, Wire and Cable Jacketing PTFE, 30% PAN Carbon Fiber EMI Shilding (conductive) PTFE, Unfilled PTFE, 25% Glass Fiber Reinforced PTFE, PTFE, PTFE, PTFE, and PE-CTFE PTFE.
