Mevopur™ Healthcare Functional Additives Laser Marking Additives for Medical Devices and Pharmaceutical Packaging Laser marking offers several advantages compared to other marking technologies. Additives can also be used to increase laser marking speed and reduce the needed laser energy. Mevopur™ Healthcare Functional Additives for laser marking are additive concentrates or ready-to-use additive formulations specially developed for use in healthcare applications.

APPLICATION BULLETIN MagIQ™ Nonwoven Electret Additives for Protective Face Masks Electret additives are used in the manufacture of nonwovens for protective face masks to impart long- lasting filtration properties. In order to ensure the middle layer in a face mask can effectively block up to 95% of airborne particles, the material requires the addition of a specific additive prior to the meltblown stage followed by a process known as electret charging. By introducing additives with charge storage properties, “charge traps” are created which capture the electret charge applied to the meltblown nonwoven material.
