SoliBoard PCW80 HT INO-Grade

SoliBoard™ PCW80 HT INO-Grade

SoliBoard™ High Temp Series are designed for high temperature applications, offering extreme durability and performance. The SoliBoard™ PCW blended boards provide a cost-effective alternative to pure PCW fiber boards.

SoliBoard™ PCW80 HT INO is made from a blend of poly crystalline fibers and our proprietary SoliWool™ HA fiber. It demonstrates less than 1% shrinkage even after 24 hours at 1600°C, but without the costs of pure PCW boards. The INO designation means it has low levels of organic binders, resulting in minimal fumes and loss of strength during first firing. SoliBoard™ PCW80 HT INO is highly resistant to various pollutants, making it ideal for demanding refractory applications.

Next to the SoliBoard™ PCW Blended grades we also offer a standard range of RCF(-Zr) Boards from 1260°C to 1430°C and the famous low bio persistence grade (LBP) families; SoliBoard™ ULS® and SoliBoard™ NXT®.

Introducing Vulcor’s SoliBoard range, manufactured on our state-of-the-art production line, a result of years of expertise and engineering excellence. Our manufacturing process sets us apart from the competition, and here’s why:

SoliBoard is produced on our continuous board line, measuring approximately 400 meter in length and a fixed production width of 1200 mm. This cutting-edge line, established in 2019, incorporates the latest standards and utilizes low-energy consumption drying technology, a unique advantage in our industry. This enables us to deliver exceptional quality while maintaining high output capabilities.

Our highly efficient drying technology reduces energy consumption by 50% compared to conventional forced air drying methods. It empowers us to manufacture uniform, lightweight, low shot, and stable boards up to 100 mm in thickness, consistently meeting the highest standards of quality and performance. In a world where reducing energy consumption and minimizing CO2 emissions is part of sustainable environmental drivers, it is good to realise that we have already taken the first step.

SoliBoard PCW80 HT INO is manufactured from a mixture of poly crystalline fibers (PCW) and a small percentage of our own developed and heat treated SoliWool HA fiber (RCF), classified at  1600°C . Our SoliBoard™ PCW80 HT INO is made from a blend of poly crystalline fibers and our proprietary SoliWool™ HA fiber. It demonstrates less than 1% shrinkage even after 24 hours at 1600°C,and performs in furnaces operating continuously at temperatures till 1480°C, but without the costs of pure PCW boards.

We tested our product at one of the leading refractory laboratories in Germany and displayed 0.8 % shrinkage when exposed for 24 h @ 1600°C. SoliBoard PCW INO-grade is manufactured with special inorganic fillers and has a very low loss on ingnition at first firing. This feature is also results in an extremely low loss of the initial green strength which is required in applications like vacuum furnaces. The PCW fiber used in SoliBoard PCW80 HT INO-grade provides solutions in applications where standard boards would not be acceptable from a strength, handling or polluting atmospheres perspective.

Vulcor provides an extensive range of high-temperature board products, including:

  • Standard boards
  • Inorganic binder boards which give lower LOI% and off-gassing
  • High-strength series with superior green strength and post-firing strength
  • Special series made from mixed fiber chemistries, often utilizing highly temperature-resistant PCW fibers, for the most demanding applications.

Because the SoliBoard SoliBoard PCW80 HT INO is manufactured using special inorganic fillers there is hardly any fumes or loss of strength at first firing.


  • Excellent insulation performance
  • Cost effective solution versus pure PCW boards
  • Can be used in direct flame contact
  • Low shrinkage
  • Excellent thermal stability
  • Low organic binder contents (INO series)


Typical applications

  • Thermal insulation for furnace linings
  • Chemical resistant lining in furnaces
  • Furnaces operating in reducing atmospheres or vacuum furnaces
  • Lining combustion chamber for gas fired boilers and heaters
  • Laboratory and dental kilns
  • General technical insulation of furnaces and technical installations



Boards from high temperature Poly Crystalline Wool (PCW) and Refractory Ceramic Fiber (RCF) wool and selected fillers.
