lntroduction:

Coace ® EM-1 is an electret masterbatch based on polypropylene, which is easy to capture free electric charge and has long-lasting polarization ability.


Coace ® EM-1 is an electret masterbatch based on polypropylene, which is easy to capture free electric charge and has long-lasting polarization ability.


The electret masterbatch typically contains a conductive or semi-conductive material, such as carbon black or metal oxide nanoparticles, and a polar material, such as a fluoropolymer or a copolymer of ethylene and acrylic acid. The conductive material provides the charge storage capability, while the polar material helps to stabilize the charge and prevent its decay over time.


The masterbatch is typically added to the polypropylene during the processing step, such as extrusion or injection molding. During the processing, the conductive particles become oriented along the direction of the flow, creating a permanent charge in the resulting product.


Electret masterbatch-based polypropylene products have various applications, including:


1.Electrostatic air filtration, where the charged polypropylene fibers can capture and hold airborne particles.

2.Electrostatic dust control in various industries, such as electronics, optics, or pharmaceuticals.

3.Electret-based capacitors or sensors, where the permanent charge can be used for sensing or energy storage.


In summary, an electret masterbatch based on polypropylene is a material that can create a permanent electrostatic charge in polypropylene-based products, and it has various applications in electrostatic air filtration, dust control, or as a component of capacitors or sensors.
