Product description
The refractory insulation blanket is made of high-quality burnt gemstones that have been melted at a high temperature of more than 2,000 degrees Celsius. A certain amount of zirconium oxide is added to the blanket. It is shaped after spinning, heat setting, acupuncture, and then rolled and packaged.
Application of refractory insulation blanket
The blanket are used for chemical industry, construction industry, electronics industry, kilns, industrial furnaces, high-temperature equipment, high-temperature pipelines and other fields for thermal insulation.
Advantages of refractory insulation blanket
◆Lightweight and low thermal conducitivty
◆High working temperature resistance and insulation
◆Superior strength for easy installation and maintenance
◆Low fiber shot contents and high resilience
◆Low heat storage for high efficiency enery savings
◆Can be foled, compressed for modules or blocks as insulation
