Combined with its high melting point, PTFE is a high. Example Applications. AGRU PFA Sheet Fabric-backed (EXTRUDED) Data Sheets. 622 c. 5 Melting point Tensile strength, 73°F Elongation, 73°F Flexural modulus, 73°F Flammability Impact strength, 73°F Weather and chemical resistance Coefficient of linear thermal expansion per. Low melting point, flexibility, transparency: Extrusion molding, tube molding, injection molding, electric wire coatings: HR-930: 20 - 35: High fluidity, resistant to stress cracking: Thin electric wires, thin-walled injection: CB-4015L:. PTFE and FEP have very similar properties, however, FEP can be more easily processed and can be simply welded and re-moulded into complex profiles. Both can be used in applications as diverse as tubing, fittings, tank linings, tower packing, fittings and valve linings, films, high purity, fibers, heat tracing wiring, avionics and specialty cables. FEP has very similar properties to PFA and in some cases can be a direct alternative. U. PTFE tubing is also an excellent insulator with surface resistivity of 3. Nafion is. PFA also has a low coefficient of friction, outstanding anti-stick properties, and is flame-resistant. Temperature Range: PFA has a broad temperature operating range, usually from approximately -200°C to +260°C (-328°F to +500°F). These two polymers have the highest extrusion temperature of all fluoropolymers with PFA processing temperature being the highest. 03 % after 24 hours Dielectric constant (Dk) at 1M Hz: 2. PFA polymers are fully fluorinated and melt processible [75], [56]. PFA 6 Copolymer PFA for Extrusion Processes . It becomes brittle at temperatures below −150 °C (−240 °F). Melt flowability and stress crack resistance are excellent. Melting point °C (°F) 171 – 175 34( 0 – 347) 158 – 166 31( 6 – 331) 162 – 168 3( 24 – 334) Heat of fusion (80 °C/176 °F to end of melting) J/g (BTU/lb)Often viewed in a class with fluoropolymers such as PTFE or PFA, PEEK polymer, however, does not contain fluorine. PCL is a popular oil-derived biodegradable thermoplastic and has. FIGURE 2. In fact, they differ significantly only with regard to cold flow (PFA better than PTFE) and folding endurance (PTF E better than PFA).
