Sell Black Flame Retardant Polycarbonate Sheets

Polycarbonate PC films and sheets have excellent impact resistance, high tensile strength, bending strength, and compressive strength; Low creep resistance and stable size; Good heat and low temperature resistance, stable mechanical properties, dimensional stability, electrical properties, and flame retardancy over a wide temperature range, suitable for long-term use at -60~120 ℃; No obvious melting point, in a molten state at 220-230 ℃; Due to the high rigidity of the molecular chain, the viscosity of the resin melt is high; Low water absorption, low shrinkage, high dimensional accuracy, good dimensional stability, and low permeability of the film; It belongs to self-extinguishing materials; Stable to light, but not resistant to ultraviolet light, with good weather resistance; oil resistant, acid resistant, not resistant to strong alkalis, oxidizing acids, amines, ketones, and soluble in chlorinated hydrocarbons and aromatic solvents. Long term exposure to water can easily cause hydrolysis and cracking. Classification of polycarbonate PC films: Black halogen-free flame-retardant PC film, transparent flame-retardant PC film, natural matte PC film, hardened PC film, scratch resistant PC film, printing grade PC film, optical grade PC film, and anti-static grade PC board Polycarbonate PC film usage: 1. Black flame-retardant PC film: used for power system insulation, disk drive insulation, keyboard insulation, TV/monitor insulation, and computer motherboard insulation. The upper and lower covers of the new energy battery pack are insulated. 2. Printing grade frosted PC film is suitable for special printing, such as helmets, signs, nameplates, protective covers, etc 3. Anti scratch PC film usage: Window lenses for electronic products such as mobile phones, backlight, etc. Property Test Method Units Value Specific Gravity ASTM D792 G/cm3 1.2 Water Absorption Equilibrium,24Hrs ASTM D570 % 0.35 Tensile Strength ASTM D882 Psi 8,800 Elongation Ultimate ASTM D882 % >90 Impact Strength @ 10mils JIS-k6745 In-ibs 120 Tear Strength Propagation ASTM D1922 G/mil >30 Vicat Softening Temperature ASTM D1525 ℃ 110 Heat Shrinkage Rate ASTM D1204 % <1.0 Dielectric Strength (@ 10 mils) ASTM D149 V/mil 1700 Volume Resistivity @25℃,50%RH ASTM D257 Ohm.m 1016 Surface Resistivity @25℃,50%RH ASTM D257 Ohm 1015 UL Flammability @ ≥ 10 mils 　UL BULLETIN94 UL94 V0 UL Flammability @ ＜ 10 mils 　UL BULLETIN94 UL94 VTM-0 Gaute Variation % ＞0.5 ±0.006mm ≦0.5 ±0.004mm
