Pyrogel® HPS

Flexible Aerogel Insulation for Industrial Applications

Optimal thermal performance in service up to 650°C (1200°F)

Pyrogel® HPS is engineered to provide optimal thermal performance and value at service temperatures up to 650°C (1200°F). With its extremely low thermal conductivity, Pyrogel HPS is up to 75% thinner than competing insulation materials. This makes it ideal for installation in congested areas or near mechanical clashes, increasing both plant safety and efficiency. Reduced insulation thicknesses also supports faster, easier application—saving time and expense.

Pyrogel HPS is tough and durable, delivering consistent performance without cracking, sagging, or settling. It can be re-used after maintenance or inspection, minimizing the time and expense required to stage replacement insulation. Pyrogel HPS is ideal for use in the fabrication of removable insulation pads. It maintains its shape and location even after vibration or exposure to high temperatures. As with all Pyrogel products, Pyrogel HPS is hydrophobic and breathable, resisting liquid water and avoiding the damaging effects of wet insulation. These unique characteristics combine to minimize heat loss and provide the ultimate protection for process units and high pressure steam pipes.

Pyrogel HPS aerogel insulation is designed to provide long-term performance for the ultimate in safety, process efficiency, and stability, in the power generation, refining, and chemical processing industries.
