Electret Masterbatch is used to increase the adsorption capacity of electric charges in melting non-wovens. It helps enchance the general filter effect and thermal decay of melting non-wovens when in standard finess and gram weight. Its advantages are, it helps to increase filter performance to 95% with standard fiber finess and grammage Applications are non-wovens with requirements on filter, medical applications such as masks and protective clothing.
