Bio-soluble Fiber Board is a revolutionary breakthrough in insulating materials technology. This kind of fiber has very high solubility in body fluids and hence classified as no hazard. This product is based on a calcium-magnesium-silica chemistry, giving excellent thermal and physical stability up to 1300 ℃. Insulating fiber products can be used in a wide range of applications, such as thermal insulation, particularly in areas of fire protection and in domestic appliances which have high requirement of environment friendly.
