EXNP is a carbon-fiber insulation used for high temperature vacuum furnace with an inert gas atmosphere. Carbon Fiber Insulation Boards are boards 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

Benefits Of Using EXNP Insulation Boards

  • Low Density, Light weight, easy to carry and install
  • Long Fiber, Rigid Needle Punch Tecnology 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 upto 2500 Degrees Celsius

OS coating is a very special and unique way of our coating method with carbon precursor to our product. The purpose of this OS coating is
1. For easy treatment with surface strengthen
2. To delay early oxidation
3. To block gas infiltration.
Hybrid surface treatment where one side is OS coating and the other side is either Foil or CFC fabric coated.
