SoliBlanket CR-Grade

SoliBlanket™ CR-grade is a specialty blanket for high-temperature furnaces with demanding atmospheres and elevated contamination. While it does not significantly differ in classification temperature (1430°C), it is designed to improve resistance to pollution up to 1300°C under suitable conditions.

It is suitable for challenging operating environments. Commonly applied in stainless steel furnaces affected by additives in specialty-grade steel, SoliBlanket™ CR-grade can deliver reliable durability where standard fiber types are pushed beyond their limits.

Product introduction

If there is one word to decribe our SoliBlanket CR-grade, the word would be tough. Where a typical RCF-Zr is at 2-3% shrinkage at 1300°C, the Soliblanket CR-grade is just over 1%… And next to the incredibly low shrinkage it also shows extreme durability in poluting atmospheres. It might not be the smoothest fiber, neither is it the best thermal insulating, but SoliBlanket CR-grade goes on were other grades of fibers stop.

Compared to other versions of a Chrome-blanket the Soliblanket CR-grade is stronger, feels more comfortable to handle and provides better thermal insulation. Even when we are manufacturing a very special grade refractory ceramic fiber, like the SoliBlanket CR-grade, the manufacturing advantage of ULS technology, keeps delivering.

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

Availability and packaging

Standard packaging

From our early start, we introduced a tight shrinkwrap packaging solution for SoliBlanket, being among the first to bring this concept to the market. Today, this approach is widely adopted, confirming its clear advantages.

Shrinkwrap packaging for blankets improves on-site efficiency and usability. Its compact form enables easier handling and smoother transport through confined spaces such as furnace manholes. It also reduces fiber dust exposure, offers better short-term weather resistance, and eliminates bulky packaging waste; resulting in faster and cleaner installation.

The concept also delivers significant logistics benefits. By optimizing pallet configuration, 24 rolls can be loaded instead of 20, allowing up to 25% more product per truck or container. This reduces transport costs and lowers the overall carbon footprint per delivered product.

Although plastic packaging has environmental considerations, we have minimized the impact by using film with recycled content. The result is a balanced solution combining operational efficiency with improved sustainability.

SoliBlanket is supplied in this optimized packaging wherever possible. On special request we still supply the carton boxes, and so do we supply our 6 mm rolls.

SoliBlanket is always supplied on ‘one-way’ pallets to optimize the required time for (un-)loading. A 40′ HC container loads a total of 520 rolls (21 pallets of 24 rolls + 1 pallet of 16 rolls) palletized and wrapped for easy and quick unloading.
