Combat™ Antimicrobial

Combat™ Antimicrobial master batch
This master batch is designed using Agion AD antimicrobial additive; a fine particle zeolite (< 4 μm) and high proportioned ionic silver (20-24%). Combat AD is commonly used in thermoplastic urethanes (TPU) and silicones for indwelling devices such as central venous (CV) catheters. Combat™ AK master batch is designed using Agion AK antimicrobial additive: a large particle zeolite (> 6 μm) and a low proportioned ionic silver (4-6%).Combat AK is commonly used in polycarbonate and acrylonitrile butadiene styrene (ABS) polymers for high-touch surface components and devices. These include bedrails, diagnostic equipment housings and instrument handles.

Agion™ Technology Silver ions are bonded to inert zeolite. The unique properties of zeolite provide selective ion exchange, absorption, separation and catalysis. The silver ions attack multiple targets in the microbe to prevent it from growing to a destructive population. This trimodal action fights cell growth by preventing respiration (inhibit transport functions in the cell wall), inhibiting cell division (reproduction), and disrupting cell metabolism.
