What is Aerogel Insulation?<\/h2><\/div>

AEROGEL is a thermal insulation material composed of heat-resistant fibers and silica aerogel powder. It is the world’s best thermal insulation, requiring less thickness compared to other types of insulation. It has a long service life, prevents external pipe corrosion, and provides long-term investment value<\/p>\n<\/div>

Aerogel Production<\/h2><\/div>

In 1930, aerogel was produced from gel in a solid jelly state where the liquid portion was replaced by air while maintaining its solid state. This resulted in an air volume of up to 90% within the gel, creating a highly complex porous structure, leading to low density and low thermal conductivity<\/p>\n<\/div>

Quality Control Standards for Aerogel Insulation<\/h2><\/div>

Aerogel Insulation is controlled by ASTM C1728 standard, which divides aerogel insulation into 3 levels<\/p>\n

    \n
  • Type I \u2013 125 \u00b0C (257 \u00b0F)<\/li>\n
  • TYPE II – 200 \u00b0C (390 \u00b0F)<\/li>\n
  • Type III – 649 \u00b0C (1200 \u00b0F)<\/li>\n<\/ul>\n<\/div>

    Within ASTM C1728, there are other standards for testing aerogel insulation to ensure specified quality<\/p>\n

      \n
    1. ASTM C177 \u2013 Thermal Conductivity<\/li>\n
    2. ASTM C165 – Compressive Strength<\/li>\n
    3. ASTM C303 \u2013 Density<\/li>\n
    4. ASTM C1101\/C1101M – Flexibility or rigidity of mineral fiber blanket or board insulation<\/li>\n
    5. ASTM C356 \u2013 Linear Shrinkage under soaking heat<\/li>\n
    6. ASTM C411\/C447 – Estimation of maximum use temperature<\/li>\n
    7. ASTM E84 \u2013 Surface burning characteristics<\/li>\n
    8. ASTM C1763 – Water Absorption<\/li>\n
    9. ASTM C1104\/C1104M – Moisture Resistance<\/li>\n
    10. ASTM C795 – Corrosion test for austenitic stainless steel<\/li>\n
    11. ASTM C1617 \u2013 Corrosion test for metal<\/li>\n
    12. ASTM C1338 – Fungi resistance of insulation material and facing<\/li>\n<\/ol>\n<\/div><\/div><\/div><\/div><\/div>

      Benefits of Aerogel Insulation<\/h2><\/div>

      Lower labor cost<\/h3><\/div>

      Due to aerogel insulation having the lowest thermal conductivity compared to other types of insulation, its thickness is less than other types, resulting in lower installation labor costs<\/p>\n<\/div>

      \"Armagel<\/span>
      <\/div>

      Armagel aerogel insulation has low thermal conductivity, allowing for thinner insulation than other types<\/p><\/div><\/div><\/div>

      Reduced Jacketing Area<\/h3><\/div>

      Aerogel reduces the required insulation thickness, resulting in reduced jacketing area. For every 1mm reduction in insulation thickness, jacketing area is reduced by 0.4%<\/p>\n<\/div>\n

      \n

      Expanded Perlite<\/td>\n150 mm<\/td>\n1.00 sq.m.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n

      When comparing aerogel with perlite insulation, the jacketing area is reduced by 47%, or when compared to the popular ROCKWOOL (Mineral Wool), it is reduced by 19%<\/p>\n<\/div><\/div><\/div>

      Reduced Piping System Weight<\/h3><\/div>

      When comparing Armagel (aerogel) with other types of thermal insulation, the weight of Armagel and jacketing is 80% lower than perlite, and 50% lower than mineral wool<\/p>\n<\/div>

      Reduced Piping System Space<\/h3><\/div>

      For limited spaces, choosing Armagel insulation reduces system space requirements (pipes can be placed closer together) due to reduced insulation thickness<\/p>\n<\/div><\/div><\/div>

      Prevention of Corrosion Under Insulation<\/h3><\/div>

      Most industrial piping systems use steel pipes with thermal insulation covering them. When insulation encounters water and moisture, it can cause corrosion on the steel pipes<\/p>\n<\/div>

      ArmaGel thermal insulation has water-resistant properties, preventing water from penetrating through to the pipe surface. It also allows water vapor to pass through the insulation to prevent vapor accumulation and condensation under the insulation<\/p>\n<\/div>
