PFA тефлон фторопласта сырья

PFA teflon(Perfluoroalkoxy alkane) It kept a PTFE excellent chemistry stability, low, high temperature resistance, dielectric property, self-lubricating,anti-sticking,ageing resistance,folding and cracking resistance are the outstanding characteristic of it, its mechanical strengh in high temperature is more than 1.6 times as PTFE.Technical Parameter: Physical Performance Specific Gravity (g/cm3) 2.12-2.17Melting Point () 302-312Mechanical PerformanceTensile Strength (MPa) 20-29Breaking Extension () 250-300Compression Intensity (MPa) 16.7Shore Hardness 60Coefficient of Kinetic Friction 0.2Melting Index 10-15Thermal PerformanceMaximal Temperature of Continuous Work () 250Thermal Distortion Temperature () (1.82 MPa) 47Coefficient of Linear Expansion x105 (K-1) 12Electrical PerformanceVolume Resistance (Ω·) 1018Insulation Breakdown Voltage (3.2mm) 20Relative Dielectric Constant (1KHz) 2.1Dielectric Loss Angle Tangent Value (tanδ)X106Hz 0.0003 Application: widely applied for home applicances, lighting equipment, electric instruments, medical unit and more at the high temperature conditions.
