SoliPaper™ PCW-Grade

SoliPaper PCW-grade, with a classification temperature of 1600°C, is the top end of our SoliPaper product range. SoliPaper PCW-grade is manufactured from a mixture of high alumina/ mullite fibers, special grade RCF fiber and special organic binders. We have developed an optimized production process to manufacture uniform, lightweight, low shot and flexible paper-like products. Where the PCW fiber component is providing low shrinkage at classification temperature the special grade RCF fibers adds handling strength to the otherwise typical fragile paper product. 


SoliPaper PCW-grade is our highest rated paper in the SoliPaper product range. The high classification temperature is the result of the use of Poly Crystalline Wool (PCW) fibers in the composition of the paper. The SoliPaper PCW-grade has a classification temperature of 1600°C and is engineered to perform in a wide range of applications operating continuously till 1480°C.

Targeted to deliver the highest possible thermal insulation value and handling strength. In this chemical composition the high alumina fiber is boosting the classification temperature where the special grade RCF fiber is providing additional strength. The combination of the two types of fiber are delivering best of both worlds.

Utilizing an optimized production process to manufacture uniform, lightweight, low shot and flexible paper-like products, we are able to create a product with a smooth surface, close dimension tolerances, exceptionally low dust, high handling strength, better thermal insulating performance and retains its flexibility after compression. SoliPaper PCW-grade is very flexible, but offers a high tensile strength as result of the high fiber index. It is particulary suited to all applications requiring further processing (laminated composites, die-cutting, rolling, folding).

SoliPaper PCW-grade is part of the SoliPaper product range. With a variety of three Refractory Ceramic Fiber (RCF) grades, a high strength paper, the PCW based paper, and the famous ‘ULS’ Low Bio Persistence Fiber grade we are offering one of the most extensive ranges of high temperature fiber paper products in the market today. With our  different chemical compositions we are able to provide a solution to nearly every atmosphere or temperature.
