Gravi-Tech™ polymer-metal composites are unique, high-density materials developed as effective alternatives to lead and other traditional metals. The high-impact polypropylene (PP)-based grades offer an excellent combination of impact, density, flowability, and colorability properties. Gravi-Tech™ polymer-metal composites are high density materials developed as thermoplastic-based alternatives to lead and other traditional metals

MagIQ™ Nonwoven Electret Additives for High-efficiency Particulate Air (HEPA) Filters The nonwoven electret additives are necessary for the manufacture of polypropylene meltblown nonwoven, used to make fresh air system filters with long-lasting filtration properties. The finer the fiber, the greater the specific surface area and the better the filtration performance. The smallest particles are extracted from the air by electrostatic attraction to the fibers.
