evolved from a requirement to improve
thermophysiological comfort whilst employing the
use of closed cell foam, elastomeric materials in
dry use on humans.
Traditionally, the use of thermal insulating materials
presented significant problems centered around the
thermal strain imposed on the user during such
use. Secondary to thermal strain is the loss of
comfort due to ‘wetting’, caused by the
accumulation of sweat.
The use of neoprene bandages to provide
therapeutic heat and support in rehabilitation
medicine is well established. However, the
duration of use is severely limited by the rapid
loss of comfort and eventual breakdown of surface
tissues through the effects of excessive heat and
Heat is continuously generated within the body by
the chemical processes of metabolism and muscle
activity. As a warm-blooded animal, it is
essential for man to maintain a body core
temperature of approximately 37║ Celsius. To
achieve this, the production of heat must be
balanced by an equivalent loss of heat. If this
balance is not maintained, thermal strain will
The body’s responses to thermal strain are
extremely efficient and are controlled by the
hypothalamus of the brain. If body core
temperature or the temperature of a specific area
of the body rises then the thermoregulatory
mechanisms are initiated in order to maintain core
temperature and thermophysiological comfort.
Conduction, convection, radiation and evaporation
are the principal means of heat loss in man. If
these mechanisms are compromised then the core or
skin surface temperature may rise.
The concept of Stomatex« was devised to prevent
this occurrence and provide conditions where
adequate sweat removal could occur whilst
preserving the inherent thermoinsulative
properties of closed cell neoprene bandages.
Thermophysiological comfort is jeopardised by
‘wetting’, whilst the presence of water vapour is
relatively acceptable to the user. However, it is
impossible to create a 'dry environment' without
excessive heat loss during the use of closed cell
foam materials. Inevitably, any system that
addresses these problems will be a compromise
between moisture control and heat loss.
The physical form of Stomatex« creates the ideal
conditions whereby water vapour may be removed, in
a controlled manner, by diffusion and forced
According to the laws of thermodynamics, heat will
always transfer from a region of high temperature
to a region of low temperature. Also, according to
the laws of diffusion, water vapour will tend to
move from a region of higher density to a region
of lower density, in an attempt to regain
Stomatex« can be employed to deliver therapeutic
heat in injury rehabilitation and the treatment of
chronic degenerative medical conditions. Use in
orthopaedic support bandages show an increase in
user tolerance from a few hours to 24 hours per
day continuous use for an indefinite period. The
unrivalled duration of wear achieved with items
made with Stomatex« makes the fabric an invaluable
asset to therapists and medical practitioners.
Interesting Information on Thermal Insulating
The thickness (thermal insulation) of the
insulating component varies from two millimetres
(mm) to six mm, with the most frequently used
being between two and five mm.
How does the technology work in the dry? The
Stomatex system has thousands of tiny chambers and
pores formed in the body of the material that
efficiently evacuates sweat as it evaporates from
the skin surface.
By controlling heat loss from the system while at
the same time removing excessive sweat. The
overall effect is to create a more comfortable
condition on the skin surface.
Used in wet conditions in thermal vests, thermal
underwear, shorts, under dry suits and wet suits,
Stomatex traps air in the chambers which, acting
as an excellent insulator, makes the garment
warmer than a similar garment made from ordinary
neoprene which does not allow sweat to evaporate.
Because Stomatex material has the ability to
remove excess heat ad sweat, the suit does not
allow the inside temperature to rise in or out of
The products are suitable for use wherever thermal
insulation or body protection is required and
comfort would normally be compromised by sweating.
It has already been used in wide-ranging
application including orthomedical supports,
sports supports, back supports, equestrian
underwear, surface watersports, wetsuits, survival
suits, surfing wetsuits, warm-up suits, dive
suits, liners and footwear.
The Stomatex« concept never fails to generate
ideas and enthusiasm…its applications are
