Calgon Carbon is a pioneer in cutting-edge textile technology. Originally developed for the British Ministry of Defence for use in chemical warfare suits, Chemviron’s Flexzorb® Activated Carbon Cloth (ACC) has many relevant uses in defense, industrial, and medical applications.
Features & Benefits
Flexzorb® is 100% activated carbon and is more effective at adsorption compared to other carbon loaded materials which have a lower activated carbon content.
Flexzorb® is available in woven and knitted formats and can also be tailored to your requirements by various activity levels, weights and thicknesses. In addition to this, value added composites can be created by laminating the cloth to other materials or impregnating the cloth with chemical treatments.
Flexzorb® has a microporous structure which results in rapid adsorption kinetics and the capability to adsorb to a higher level of purity. Flexzorb® is also suitable for use in applications where there is a high humidity as its adsorption capacity is less adversely affected by moisture. The activated carbon cloth can also be custom-manufactured to comprise a mesoporous structure to adsorb larger molecules if required.
Due to its microporous structure, Flexzorb® activated carbon cloth has an extremely large surface area. To put its capabilities into perspective, just 1g of Flexzorb® activated carbon cloth has the surface area of over half the size of a football pitch. This, combined with the strong electrostatic forces within the cloth, enables the cloth to be highly efficient at adsorbing both liquids and gases.
Flexzorb® has been tested by the UK’s Health Protection Agency and have been proven to be both antiviral and virucidal (when tested against surrogate virus MS2-Coliphage).
Markets and Applications
The inclusion of Flexzorb® activated carbon cloth (ACC) considerably enhances the efficacy of both advanced and active wound dressings. The antimicrobial properties of Flexzorb® can be further enhanced by a unique impregnation process which produces a dispersion of nano and micro particles of metallic silver – one of the most effective biocides known to man. Other impregnations are also possible.
As well as possessing antimicrobial properties, Flexzorb® also enables the wound to heal due to its naturally permeable properties which enhance the breathability of the cloth. The Cloth Division has the manufacturing capability to produce the entire wound dressing product containing activated carbon cloth including procedures such as pouching, sterilization and labeling. Chemviron Carbon Cloth Division also produces cloth used in Negative Pressure Wound Therapy (NPWT) devices where wound exudates are collected due to its ability to adsorb odor.
Chemviron Carbon’s Cloth Division possesses the ISO 13485 standard for the manufacture of medical devices.
Flexzorb’s high performance to size ratio is ideal for use as a filter for vented ostomy bags. To help improve the quality of life for ostomy patients, Flexzorb® very effectively removes all odor and also controls the release of gases thus preventing ballooning (too slow an air flow) or pancaking (where the air flow is too fast).
In the defense sector, Flexzorb® is used where protection to a wide range of chemical, biological or nuclear agents is required (i.e. protective clothing, filters and decontamination wipes). Flexzorb® offers the most effective protection on the market today with low physiological burden at low carbon weights.
Environmental Air and Industrial Products
The opportunities to use Flexzorb® to support a vast range of industrial products and manufacturing processes are limitless. Due to the numerous attributes of Flexzorb® it can be used for a wide range of filtration applications that include air conditioning, catalyst media, emission control, purification filters, solvent recovery, VOC filtration, and water filtration to name a few. Flexzorb® activated carbon cloth can also be laminated to other support media to allow pleating of the cloth and is therefore useful for various industrial filtration purposes.
