the product suit for a wide range of working temperature. meanwhile its important value lies in the property stability through long service hours. besides,the material itself is fire protective and shock resistant.when used in low-temperature,undergroud engineering projects, flammable and explosive,humid environments as well as environments with severe chemical corrosion, this material is not only safe and reliable but durable as well.therefore,it is known as"the permanent insulation material that needs no replacement".adopting the glass powder as the base material and added with addictives,it is obtained by means of baking and bubbling in tunnel kilns before anealing and cooling down. the characteristics of this material is: 1.low density,approxinmately 150kg/m³ 2.low thermal conductivity;under 0.060 w/m·k(38°C),the thermal conductivity is stabilized 3.humidity resistance 4.low moisture absorption tate,around 0.2% 5.inflammable 6.mold resistant,corrosion free 7.high strength,press resistance≥0.7mpa;bending resistance≥0.5mpa 8.acid corrosion resistant(except forhydrogen fluoride） 9.non-toxic,containing no CFC and HCFC 10.stable physical and chemical performance, stable dimension
