SoliPaper ULS-Grade

SoliPaper™ ULS®-Grade

We are proud to introduce you our SoliPaper ULS which is setting a new standard for low shot low bio persistence fiber based paper products. Utilizing the Generation III, Ultra Low Shot, fibers we are able to offer you a paper with is differenciation on very smooth surface, higher mechanical strength and close dimensional tolerance.  It is particulary suited to applications requiring further processing (laminated composites, die-cutting, rolling, folding).

SoliPaper ULS-grade, as the original, has several spin-off products like the SoliPaper ULS LOWPAC and the ULS High Strength which have been developed to fill specific requirements from the market. SoliPaper ULS-grade has a classification temperature of 1260°C and is recommended for use up till 1100°C continuously.

SoliPaper ULS-grade is our standard Low Bio Persistence fiber paper product and is used in a wide range of applications with great success.  SoliPaper ULS-grade has a classification temperature of 1260°C and is recommended for use till 1100°C continuously.

SoliPaper ULS is manufactured from true Generation III ultra clean and fine SoliWool fiber. SoliPaper ULS is very flexible, and offers a high tensile strength thanks to the high fiber index. As a result it is particulary suited to all applications requiring further processing (laminated composites, die-cutting, rolling, folding).

Utilizing an optimized production process we are able to create a product with a smooth surface, close dimension tolerances, exceptionally low dust, high handling strength, and an improved thermal insulating performance. SoliPaper ULS-grade is very flexible, and offers a high tensile strength as result of the high fiber index.

SoliPaper ULS is using organic binders which burn out on the first firing, starting at approximately 250°C.

All products in the SoliWool ULS fiber product range, like the SoliPaper ULS, meet the requirements specified under NOTE Q of European Regulation 1272/2008. All  SoliPaper ULS products are therefore exonerated from labelling requirements in Europe.

Next to the SoliPaper in the low bio persistence grade (LBP) we also offer a standard range of RCF(-Zr) Papers from 1260 to 1430°C and special paper grades using PCW fibers up till 1600°C.

Next to the standard rolls we also supply our SoliPaper ULS-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.
