SoliPaper ULS-Grade

Product introduction

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.

Availability and packaging

Packaging Options Designed Around Your Process

SoliPaper ULS-grade is available in two packaging formats, allowing customers to select the most efficient solution for their manufacturing and maintenance requirements.

Standard Rolls are supplied in widths of 610 mm and 1220 mm and packaged in compact cardboard cartons. Depending on the roll width, up to 42 rolls (610 mm) or 21 rolls (1220 mm) can be supplied on a single pallet. This format provides maximum flexibility for maintenance operations, workshops and lower-volume gasket production while ensuring easy storage, handling and material management.

Jumbo Rolls have been developed for high-volume converting and gasket manufacturing operations. The larger format significantly reduces roll changes, material handling and production interruptions, enabling continuous processing and higher throughput. Combined with the enhanced green strength of SoliPaper ULS-grade, converters can efficiently die-cut large quantities of gaskets and custom shaped components with excellent dimensional consistency and minimal material loss. The result is increased productivity, reduced labour requirements and lower processing costs in demanding production environments.

SoliPaper JumboRoll Dispenser System – From Delivery to Production in Minutes

The SoliPaper JumboRoll™ Productivity System transforms the jumbo roll from a logistical challenge into a production-ready manufacturing format. Each roll is supplied in an integrated carton dispensing unit that protects the material during transportation, storage and processing.

Designed specifically for gasket converters and high-volume cutting operations, the system eliminates the need for dedicated unwinding stations, secondary handling and unnecessary material transfers. Operators simply position the pallet adjacent to the cutting equipment and feed the material directly into production.

The integrated rotating-core design provides smooth and controlled unwinding while maintaining maximum roll stability. By reducing handling steps and setup time, manufacturers can increase productivity, improve operational efficiency and reduce the risk of product damage.

This unique concept turns packaging into a functional production tool, helping gasket manufacturers process more material with less effort and greater consistency.
