SoliBoard PCW INO-Grade

The SoliBoard PCW INO-grade, with a classification temperature of 1600°C, is the top end of our SoliBoard product range. We manufacture our SoliBoard PCW INO from a mixture of poly crystalline fibers and a small percentage of our own developed and heat treated SoliWool HA fiber. The result of our developement is a product which is showing less than 1% shrinkage even if tested at 1600°C . As the SoliBoard PCW INO-grade is manufactured using special inorganic fillers there is hardly any fumes or loss of strength at first firing.

SoliBoard PCW INO-grade is part of our SoliBoard Special Grade product range. The SoliBoard Special Grade product range consists of board which are all designed for a special purpose. Either these boards have been developed for high strengh or extreme durability and the most demanding applications.

We manufacture the SoliBoard product range on our continuous board line, with state of the art drying techniques. This drying process is much more sustainable, leading to 50 % energy saving compared to conventional drying techniques and allows us to dry the product to the core to a thickness of 100 mm. As it is manufactured on our continuous board line, which spans over 200 m (600 ft), our product are much more controlled and consistent compared to batch manufactured vacuum forming process boards. As a result we can offer you a uniform, lightweight, low shot and stable board at high consistency, quality and performance.

The SoliBoard PCW INO-grade has a classfication temperature of 1600°C and engineered to perform in a wide range of applications up till 1500°C continuously. The SoliBoard standard product range consists of 3 types of standard refractory ceramic fiber (RCF) boards, an extensive range of low bio persistence (LBP) boards. We also deliver a Special Grade Boards range for High Strength or, and this PCW fiber based board for the most demanding applications.
