Ultra-Wide Temperature Range Stability
This product offers long-term stable operation from -200°C to +650°C, with some customized models offering short-term temperature resistance up to 700°C. This product is suitable for applications such as high-temperature pipelines in thermal power boilers (300-600°C), hot air ducts in metallurgical blast furnaces (400-650°C), and petrochemical reactors. Its nano-aerogel skeleton maintains structural integrity even at high temperatures, avoiding the performance degradation associated with high-temperature melting or crystallization of traditional materials such as rock wool.
Differentiated Positioning from the HT1200
The HT650 and HT1200 (temperature resistance 1200°C) belong to the same aerogel insulation blanket family, but their core differences are:
Cost Advantage: The HT650 is more affordable and suitable for general-purpose applications in medium- and high-temperature environments;
Lightweight: Its density is 10%-20% lower than the HT1200, making it more suitable for weight-sensitive equipment;
Flexibility: The HT650 offers a smaller bend radius (≤50mm), adapting to more complex piping layouts.
Thermal Conductivity Variation with Temperature
At room temperature (25°C): the thermal conductivity is as low as 0.012-0.016 W/(m・K), only one-third that of traditional rock wool.
At high temperature (200°C): the thermal conductivity is ≤0.025 W/(m・K).
At 300°C: the thermal conductivity is ≤0.036 W/(m・K), still superior to ceramic fiber felt at the same temperature. This feature enables it to effectively reduce heat loss even under high-temperature conditions. For example, in a certain thermal pipe network project, HT650 reduced insulation thickness by 50% and increased energy savings by 34.6%.
Lightweight and High Strength
Density: 150-300 kg/m³, only 1/2-1/3 that of traditional materials, significantly reducing equipment load.
Tensile Strength: ≥200 kPa, with tear resistance superior to pure aerogel, capable of withstanding mechanical vibrations in industrial environments.
Compression Resilience: ≥90%, ensuring long-term deformation and preventing thermal bridging caused by material settling.
Fireproof and Hydrophobic Properties
Fireproof Rating: Meets the Class A non-combustibility standard of GB 8624-2012. No toxic gases are released during combustion, making it suitable for use in applications with stringent fire protection requirements (such as nuclear power plants and ships).
Hydrophobicity: ≥99%, with a closed-cell structure that effectively blocks liquid water intrusion, preventing moisture-induced degradation of thermal insulation performance.

FAQ:
In typical application cases of the Aerogel Blanket HT650 (such as the Beijing heating network and petrochemical reactors), what specific data demonstrates its actual energy-saving and safety-enhancing effects?
The results of two typical cases can be quantified through key data: First, in a Beijing heating network renovation project (DN800 hot water pipes), the use of HT650 reduced the insulation thickness from 100mm (traditional materials) to 50mm (reducing space requirements by 50%), achieving an energy saving rate of 34.6%, saving approximately 1.2 million cubic meters of natural gas annually, equivalent to reducing CO2 emissions by approximately 2,640 tons. Second, in a petrochemical company's reactor project, the use of HT650 insulation reduced the reactor surface temperature from 180°C (far exceeding occupational safety standards) to below 50°C, completely eliminating the risk of burns for operators. Furthermore, due to reduced heat loss, steam consumption was reduced by approximately 800 tons annually, equivalent to a cost savings of over 600,000 yuan. These data directly verify its dual value of "energy saving + safety".
