EXNP is a carbon-fiber insulation used for high temperature vacuum furnace with an inert gas atmosphere. Carbon Fiber Insulation Boards are used to prevent loss of heat in highly technical operations in industries like Heat Treatment, Vacuum Furnace, Solar Cell Manufacturing, Silicon Ingot etc. These boards are made with specialized material to withstand temperature exceeding 2300°C, which no other material can do.
- Our Insulation Boards – EXNP – are made by patented needle-punch technology. This technology is specifically used to make C/C Composite plates and other C/C products. And for the first time in the world, this technology has been incorporated to make Carbon Fiber Insulation boards
- Low thermal conductivity and low C.T.E makes our boards high on energy saving
- It can be customized to any shape and size as per customers’ requirement
- Delivery within 7-10 working days, subject to availability of stock
- Pioneer in incorporating Needle-punch technology for making Rigid Insulation Boards
- EXNP – Only Rigid Insulation Board of the world, made by Needle-punch technology
- One & only supplier of non-Chinese Carbon Fiber Rigid Insulation Boards in India

Benefits Of Using EXNP Insulation Boards
- Low Density, Light weight, easy to carry and install
- Long Fiber, Rigid Needle Punch Technology makes EXNP boards Tough and Durable with high mechanical strength and high performing product.
- Our EXNP boards have low CTE and thermal conductivity. The lower the CTE the less expansion and contraction of the board when heated. This in turn increases the life of the furnace and its parts further increasing the efficiency of the furnace.
- Withstand up to 2500 Degrees Celsius
