SoliPaper ZR-Grade

SoliPaper ZR-grade is a zirconia-enhanced refractory ceramic fiber paper developed for high-temperature sealing, gasketing and expansion joint applications. Available in thicknesses from 1 to 10 mm, it combines excellent flexibility and mechanical integrity with improved resistance to shrinkage at elevated temperatures. The alumina-silica-zirconia fiber composition extends the operating envelope beyond standard 1260°C RCF paper grades, making SoliPaper ZR-grade particularly suitable for furnace door seals, hot-face gaskets and thermal barriers. It has a classification temperature of 1430°C and a maximum continuous use temperature of 1300°C.

Product introduction

SoliPaper ZR-grade is our highest positioned refractory ceramic fiber paper (RCF-Zr)1430 in the SoliPaper product range, only having the SoliPaper PCW to outperform on classification temperature. The high classification temperature is the result of the use of Zirconia in the chemical composition of the fiber. The SoliPaper ZR-grade has a classification temperature of 1430°C and is engineered to perform continuously in a wide range of applications up till 1300°C.

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 ZR-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 ZR-grade is part of the SoliPaper product range. Next to the SoliPaper from RCF(-Zr) fiber we also offer an extensive range of low bio persistence grade (LBP) papers and special paper grades using PCW fibers up till 1600°C.

Availability and packaging

Packaging Options Designed Around Your Process

SoliPaper ZR-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 ZR-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.
