Antibacterial electret masterbatch

Short Description:

Electrode is a dielectric material that has the function of long-term storage of charge and releases negative ions. The stored charge can increase the electrostatic adsorption of masks and the sterilization of negative ions, effectively blocking off the foam, dust, bacteria and aerosol below micron. Silver ion antibacterial agent is a kind of high energy efficiency antibacterial anti-virus additive, which has a good bactericidal effect on Escherichia coli, Staphylococcus aureus, Candida albicans, Pneumococcus, pseudomonas aeruginosa, etc., and also has a good inhibitory effect on various kinds of fungi and viruses containing protein capsid.

Product introduction

Mp203-ly95 antibacterial melting and spraying electret masterbatch takes melting and spraying polypropylene as the base material, adopts super dispersant and special blending extrusion equipment, so that nano electret additive and silver ion antibacterial agent are evenly dispersed in melting and spraying polypropylene base material. This product can increase the density and depth of charge trapping trap in melt spray non-woven fabric, release negative ions and storage charge effectively, and improve the filtration efficiency of melt spray fabric and the performance of resisting humidity and heat electrostatic attenuation. In addition, this product adds a new function of anti-bacteria and anti-virus to the melt spray non-woven cloth, which greatly increases the safety of the mask. 

Product feature

■ Good electropole effect can increase electrostatic charge density and help pass the 95 test;
1. Long-term static performance, up to 3 years.
■ Self-sterilization
1. has a good bactericidal effect on Escherichia coli, Staphylococcus aureus, Candida albicans, Pneumococcus, Pseudomonas aeruginosa, etc.;
2. It has a good inhibitory effect on other fungi and viruses.
■ with good processing performance
1. Nano-level additives do not plug holes, and the process is stable
2. No need to add new equipment, no need to significantly adjust the existing melting spray non-woven production process;
3. It does not affect the normal cleaning cycle and service life of spinneret.
■ Safe, healthy and non-stimulating
■ No drug resistance
■ Long-lasting antibacterial properties
