1. Relevant about Glass wool felt Via CE Certificate , Non-combustibility GB testingFire resistance, anti-moisture, compression resistance.Excellent quality and Competitive price(PRODUCTION LINE) 2. Main specification range: Thickness: 50mmDimension: 2800mm×600mmMaximum working temperature: 400°C 3. Fire resistance Incombustibility of Gootren glass wool series products (Grade A) is qualified upon inspection and determination of National Quality Supervision and Examination Center of Fire Proof Building Material according to national standard GB5464-1999 and GB 8624-1997 4. Anti-moisture After exposing for four days under a temperature of 50°C, a relative humidity of 95% and pressure, hygeoscopicity of Gootren glass wall filling wool felts is below 2.0%. If products are damped, their performance can be completely recovered after drying. It should try best to keep the products dry and prevent entry of moisture and water. 5. Corrosion resistance Gootren glass wool felt series products are free of any chemical reaction and tend to weak alkali, with a PH of 7.5-8.0; therefore, it will not cause rust and corrosion of steel. It should prevent exterior pollution from staining the wool felts and keep the original state of such products. 6.
