Antimicrobial and antifungal additives can protect the user interfaces and touchpoints from mold, mildew, and bacteria, while antistatic and conductive formulations can prevent static discharge and create safer, statically dissipated plastic parts.   These types of additives can help the polymer surface withstand extreme temperatures, wind, sunlight, exposure to chemical cleaning products, or surface damage from excessive handling.

HEPA HEPA is a type of pleated mechanical air filter. This type of air filter can remove at least 99.97% of dust, pollen, mold, bacteria, and any airborne particles as small as 0.3 microns (µm). This requires the addition of a specific additive to the masterbatch prior to the meltblown stage, followed by a process known as hydro electret charging.
