SoliPaper X-Grade

SoliPaper™ X-Grade

SoliPaper X-grade is our standard Refractory Ceramic Fiber (RCF) 1260 paper which is available for use in a wide range of applications. The SoliBulk X-grade, which is the main component of manufacturing process of the SoliPaper X-grade, is one of the products taking most benefit of the Generation III, Ultra Low Shot fiber technology. In result the SoliPaper X-grade, compared to standard RCF papers, excels in the highest possible thermal insulation value and handling strength. SoliPaper X-grade is manufactured from our standard 1260°C rated RCF SoliWool bulk and special selected fillers. With a classification temperature of 1260°C it is recommended for use up till 1100°C.

​SoliPaper X-grade is the most standardized of our three Refractory Ceramic Fiber based paper products and is used in a wide range of applications with great success. It is also one of the products which takes most benefit of the Ultra Low Shot spining technology, which is commonly used for the production of our fiber products. SoliPaper X-grade has a classification temperature of 1260°C and is recommended for use till 1100°C continuously.

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 X-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 X-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.

SoliPaper X-grade is manufactured in a density of 190 to 210 kg/m3 and in a standard thickness range from 1 till 10 mm. Our SoliPaper is standard available in both Jumborolls and standard rolls.

SoliPaper in standard rolls is supplied in carton boxes. All our paper are packed on a heat treated export pallet. Standard rolls are packed with 42 rolls per pallet. Please refer to the list below for dimensions of the standard rolls, other sizes and thicknesses are available on request.

Next to the standard rolls we also supply our SoliPaper X-grade in Jumbo Rolls. Jumbo Rolls are ideal for large quantity die-cut gaskets which can be used in the automotive –and domestic appliances industry, minimizing cutting waste. The jumborolls have a standard width of 1200 mm which allow them to be loaded with 4 rolls per pallet. The jumborolls are provided with heist belts in the roll which allow swift loading on the feeder for high volume gasket cutting.
