| The exo² FabRoc™ and ThermoKnitt heating technologies are unique, 21st century fabrics that produce heat when low voltage is applied.
Under constant improvement and development for over 30 years, FabRoc™ can be heated by a variety of power sources (rechargeable batteries, 12v accessory outlets, and direct connection to motorcycle, ATV, etc. batteries, and even 120v household current with a convertor). By regulating the voltage, FabRoc™ will heat to pre-defined temperatures (over to 130° F depending on the product, power source and electrical configuration), creating uniform heated surfaces with no hot spots. Uniform distribution and dissipation of heat allows the heating element to be located in close proximity to the heated area in order to maximize warmth and minimize response time. |

| The FabRoc™ polymer is loaded with specially blended conductive particles, which enhance its conductivity properties and exhibits a Positive Temperature Coefficient (PTC) when heated.
PTC means that as the temperature of the FabRoc™ heat technology increases, its electrical resistance also increases in a non-linear fashion. Once the material reaches the desired temperature, it self-regulates by drawing less electrical current until power is again required. |

How do the heating components work?
When the heating element is at room ambient temperature, numerous conductive "chains" exist within the material. When low voltage is applied, current flows through the element, causing a rise in heat. Once the heat rises, it creates a small expansion, causing the conductive particles to move apart from each other. As the resistance of the element increases, the material conducts less current and temperature is regulated. |

| Key Features
FabRoc™ is virtually indestructible. This rubber-like structure is flexible enough to be configured into almost any shape. Freezing temperatures have no effect on the flexibility of FabRoc™ making it ideal for heated clothing and suitable for a broad range of other commercial applications.
Unlike wire-based or carbon fiber heating systems, FabRoc™ continues to operate even if it is slit or torn, with NO POSSIBILITY OF SHORT CIRCUITING. Operating from low voltage means that heating systems for moderate users can be powered by rechargeable batteries. The weight of these battery packs (no heavier than a modern mobile phone) makes the heating system ideal for portable use. |
FabRoc™ is:
>Intrinsically safe (due to the PTC properties and cannot overheat)
>Inert (resistant to most chemicals making it ideal for use in extreme environments)
>Energy Efficient (converting over 98% of electrical energy into heat)
>Lightweight (yielding virtually unlimited applications)
>Waterproof and Windproof
>Crushproof and Stretchable (with up to 200% elongation before rupture, but FabRoc™ is normally backed by netting to provide additional or required strength). |

Today, e-textiles can offer 'wireless communication' and 'wearable computing'. exo² is taking this a step further in marketing the first, intrinsically safe, and totally adaptable, textile and polymer based heated clothing system. A combination of conductive yarn, braiding and carbon loaded silicon elements can be applied to an almost limitless range of product applications where there are no wires to break (or overheat) and no solid panels to accommodate (unless they are a requirement of the specification). Discreet and efficient energy sources, operating at very low voltages (3.7v - 14.8v typically) and a virtually indestructible core heating material makes this technology ideal for the 21st century marketer. To increase our already wide range of applications, these two additional technological advances are being pursued and patented.
ThermoKnitt - A conductive polymeric yarn allowing our heat technology to be "knitted-in" during the glove or mitt manufacturing process.
ThermoMesh - The arrangement of FabRoc™ into a mesh which is treated, cut and shaped to achieve the precise coverage and temperature levels required by the customer or application. |
