Performance Electret Additives

MagIQ™ Nonwoven Electret Additives

Improves Dielectric Properties

MagIQ™ Nonwoven Electret Additives are electret masterbatches necessary for the manufacture of meltblown nonwoven polypropylene used to make nonwoven fabrics with long-lasting filtration properties for consumer, building & construction, automotive and appliance applications. 

Electret charging works by improving the crystallinity and mechanical deformation of a material, to prevent electret charge from drifting. By introducing additives with charge storage properties, “charge traps” are created which capture the electret charge that is applied to the meltblown nonwoven material.

Charging only works when the correct masterbatch is utilized, and together with the fiber denier, gram weight and number of layers, ensures the middle layer of protective masks can effectively trap smaller particles.

Manufacturers can use either hydro charging or corona charging processes.
