ZORFLEX - ACC - Activated Woven Carbon Cloth - Brochure

DESCRIPTION Activated Carbon Cloth (ACC), originally invented in the 1970’s has since been developed by Chemviron Carbon Cloth Division for use in many filtration, adsorption and separation applications for use in industrial, medical and domestic markets ZORFLEX® ACC has an extremely large surface area (1000-2000m2/g), being predominately microporous. This, combined with the strong electrostatic forces developed within the cloth, enables the cloth to be highly efficient at adsorbing vapours and solvents. Available in woven and knitted formats, the cloth is also offered in different activities, weights and thickness. The cloth can also be impregnated with chemical treatments to make it more sensitive to adsorption of particular inorganic molecules. FEATURES ZORFLEX® ACC’s have several properties, which explain their superior performance in a wide range of applications: ? As the material is 100% activated carbon, the cloth’s performance will exceed that of an equivalent weight of a conventional carbon loaded paper, non-woven or foam, due to their lower carbon content. ? The materials flexible textile form offers superior handling in filter and product manufacture and makes lamination or bonding to other materials possible. ? This form of activated carbon cloth exhibits more rapid reaction and adsorption kinetics compared with granular activated carbon. Therefore, ZORFLEX® ACC filters will be more effective when short contact time, high airflow speeds or small bed depths are required. ? A greater amount of vapour will be adsorbed by ZORFLEX® ACC compared with the same weight of granular activated carbon. Therefore ZORFLEX® ACC filters will be more effective in high vapour concentrations or where smaller bed depths are required. ? ZORFLEX® ACC’s high efficiency and large capacity for adsorption are less adversely affected by preadsorbed moisture than granular activated carbon. Therefore ZORFLEX® ACC filters are more suitable for use in humid environments where their effectiveness will be maintained. APPLICATIONS ? Oil mist filters in compressed air ? Gas sensor protectors and filters ? Protection of artefacts from tarnish and degradation ? Water and air purification ? Escape masks ?

SAFETY MESSAGE Wet activated carbon preferentially removes oxygen from air. In closed or partially closed containers and vessels, oxygen depletion may reach hazardous levels. If workers are to enter a vessel containing carbon, appropriate sampling and work procedures for potentially low-oxygen spaces should be followed. QUALITY Chemviron Carbon Cloth Division has achieved ISO 9001 quality certification, ISO 13485 standard for the manufacture of medical devices and ISO 14001 environmental standard.
