Molding and Extrusion PTFE is a subcategory of Fluoroplastics. It is specially formulated to molding and extrusion. Its elastic modulus ranges from 200 to 80000 MPa. Its flexural modulus ranges from 170 to 120000 MPa. Its tensile strength ranges from 3500 to 7250 MPa at break. Its flexural strength ranges from 9700 to 13650 MPa. Its compressive strength ranges from 8000 to 16000 MPa. Its Izod Impact strength ranges from 2.5 to 80 J/cm. Its elongation at break ranges from 12 to 600 %. Its hardness ranges from 79 to 83 Rockwell R. Its specific gravity ranges from 1.77 to 1.78. Its coefficient of thermal expansion ranges from 70 to 142 x 10-6/°C. Its melting temperature ranges from -60 to -20 °C. Its molding pressure ranges from 2 to 5 MPa.
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.
Other common Fluoroplastics (PTFE) include PTFE, Granular PTFE, 25% Glass Fiber Reinforced PTFE, PTFE, Unfilled PTFE, 20% Milled Glass Fiber PTFE, Unfilled Film PTFE, Filled Film 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.
