Saint-Gobain M824 polyester films have excellent dimensional stability, high tensile, tear and impact strengths and ultimate elongation up to 120% of its original dimensions. These films exhibit low water absorption and good resistance to oils, greases, strong acids and organic solvents. - They also retain electrical properties, dielectric strength and dielectric constant in continuous operating temperatures from -100 to 350 °F. Recommended for all splicing applications including oven splicings where good wet-out capabilities are critical.
