SoliBlanket ZR-Grade

Vulcor is proud to present you the second of our 3 fiber blankets ranges were the Generation III spinning technology is delivering the full potential of the product; the SoliBlanket ZR-grade. With our Generation III spinning technology, coarse shot is part of history. We call this technology our Ultra Low Shot technology (ULS).

Compared to conventional Refractory Ceramic Fiber (RCF-Zr) blankets, the SoliBlanket ZR-grade is differentiating with the highest possible thermal insulationvalue, improved mechanical strength and better handling properties. This is not just a random claim; this is what you see and feel when working with the product.

Of our SoliBlanket Standard RCF productrange the SoliBlanket ZR-grade is our main refractory ceramic fiber (RCF-Zr) 1430 blanket. We ensure the high classification temperature by the chemical composition, which means we have a tight control on the zirconia contents of our blankets.The SoliBlanket ZR-grade has a classification temperature of 1430°C and is engineered to perform in a wide range of applications up till 1300°C continuously.

The 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. The full SoliBlanket product range consists of five grades of Refractory Ceramic Fiber (RCF) and one grade in Low Bio Persistence (LBP) fiber blanket.
