Electret materials are widely used in the field of high efficiency and low resistance air filter materials. Electret air filter materials require high density of stored charge, long life and high stability. The raw materials used as electrets need excellent dielectric properties, such as high volume resistance and surface resistance, high dielectric breakdown strength, low moisture absorption and air permeability.
Organic Fluorine Electret Powder 53 has a very high electrostatic capacity, the micropores distribution is uniform, it can increase the electrostatic adsorption capacity of PP, and it can effectively extend the aging of charge storage for one year, it is suitable for the production of melt blown cloth with filtering efficiency of 95 or 99. |
