SoliBlanket™ ZR-Grade

The Standard Grade RCF range SoliBlanket consists of 2 types of Refractory Ceramic Fiber blankets for the temperature range of 1260°C to 1430°C : the X-grade and the ZR-grade. The SoliBlanket ZR-grade is our standard RCF-Zr blanket which has a classification temperature of 1430°C and is recommended for use in temperatures up till 1300°C continuously. 

To differentiate our classic RCF-Zr blanket from the competition offering we ensure the high classification temperature by the chemical composition. This means we have a tight control on the zirconia contents of our blankets, and we benefit from the use of our ULS spinning technology.

As a result Soliblanket ZR-grade is stronger, feels more comfortable to handle and provides better thermal insulation. During installation the benefit of our advanced spinning process offers a higher resiliency after compression. This is particularly important when making fiber modules or in case the blanket (strip) is installed perpendicular to the main fiber orientation, or in easier words; stack(bonded).

SoliBlanket ZR-grade is part of the SoliBlanket product range. With a variety of five 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.
