WebApr 8, 2024 · The lower the dissipation factor, the less energy is absorbed from an electric field. For polymers that will be heated in a radio frequency or microwave oven for welding, drying, etc., the high dissipation factors are crucial. High capacitance materials must also have a high dielectric constant and a low dissipation factor. In physics, the dissipation factor (DF) is a measure of loss-rate of energy of a mode of oscillation (mechanical, electrical, or electromechanical) in a dissipative system. It is the reciprocal of quality factor, which represents the "quality" or durability of oscillation.
