CCEWOOL® PUREWOOL® RCF Blanket for Fabrication

CCEWOOL® PUREWOOL® RCF Blanket for Fabrication is a high-purity ceramic fiber blanket developed for demanding high-temperature engineering applications. The product is manufactured using high-purity synthetic raw materials including alumina, silica, and zirconia. Through optimized formulation and fiberization technology, the blanket achieves higher fiber purity, lower impurity levels, and a cleaner white fiber appearance. As a result, the material offers lower shrinkage, improved thermal insulation performance, and greater structural stability under high-temperature operating conditions.

Compared with conventional industrial-grade ceramic fiber blankets, PUREWOOL® RCF Blanket for Fabrication provides improved fiber length, structural uniformity, and mechanical strength. The blanket is produced using an extra-long spun fiber structure combined with double-sided internal needling, creating a stable three-dimensional interlocking fiber network throughout the material. This structure significantly enhances the tensile strength and overall structural integrity of the blanket, with tensile strength reaching up to 90 kPa.

CCEWOOL® PUREWOOL® RCF Blanket also offers excellent Fabrication compatibility. The material can be easily cut, layered, or structurally processed to meet specific engineering requirements for high-temperature insulation systems in industrial equipment. In addition, CCEWOOL® provides the blanket in a wide range of thicknesses, widths, and densities, allowing customers to select the most suitable configuration to improve energy efficiency and insulation performance in different industrial applications.
