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

Wound Care

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. We have the manufacturing capability to produce the entire wound dressing product containing activated carbon cloth including procedures such as pouching, sterilization and labeling if necessary.
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).

NPWT Devices

In Negative Wound Therapy (NWTP) devices, Flexzorb® is used as a filter for wound exudate odour management in the part of the device where wound exudate is collected.

Drug Delivery Devices

Flexzorb® can be used as a filter medium in closed-system drug delivery devices for the safe delivery of oncology and other such hazardous drugs. The filter protects both patients and healthcare professionals from respiratory exposure, helping reduce negative health effects from long term exposure to hazardous drugs in the healthcare environment.

CBRN Defence Garments

Flexzorb® offers excellent properties as a CBRN liner fabric for integration into defence garments for infantry forces, special forces, and pilots. Flexzorb® liner fabrics provide the most effective chemical and biological agent protection on the market today with low physiological burden, industry-leading breathability, and superior comfort.

Other Defence Applications

Flexzorb® can also be used in decontamination wipes and mitts, missile decoy media, PPE, and as phosphine gas adsorption media.

Air Filtration and Industrial Uses

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:

  • VOC filtration
  • Oil mist separation
  • Industrial and domestic air purification
  • Pollution protection masks
  • Antiviral and antimicrobial masks
  • Escape hoods
  • Cabin air filtration
  • Solvent recovery
  • Gas sensing and detection
  • Anti-tarnishing media for artefact conservation
  • Pollution Abatement
  • Energy storage
  • Catalyst media

Flexzorb® activated carbon cloth is useful for a wide range of industrial filtration purposes thanks to the customisation options we can provide such as lamination to other support media to allow pleating, particulate filtration, and additional functionality. We can also provide chemical impregnations into the structure of Flexzorb® to aide in the removal of additional gases that you may wish to target with even greater efficiency.
