Pyrogel® XT-E

Flexible Insulation for Hot Work

Pyrogel® XT-E is the most effective high-temperature insulation material in the industrial market, typically 2-5 times thinner than other widely used insulation products. It is our easiest product ever to handle, store, and install. Pyrogel® XT-E offers the same industry-leading thermal performance as Pyrogel® XT, with standard roll sizes and a product form that dramatically reduces handling dust and simplifies installation and clean-up.

Pyrogel® XT-E is used for a wide range of industrial applications including refineries, petrochemical, and gas processing. Pyrogel® XT-E high-temperature insulation is efficient, durable, and more productive to install. Its water resistance offers a level of protection against corrosion under insulation (CUI). 

Pyrogel® XT-E delivers industry-leading high thermal performance in a flexible, environmentally safe, and easy-to-use industrial insulation product.

Superior Thermal Performance

Up to five times better high-thermal performance than competing insulation productsReduced Thickness and Profile

Equal thermal resistance at a fraction of the thickness

Less Time and Labor to Install

Pyrogel® insulation is easily cut and conformed to complex shapes, tight curvatures, and spaces with restricted access

Physically Robust

Soft and flexible but with excellent springback, Pyrogel® XT-E recovers its thermal performance even after compression events as high as 100 psi

Shipping and Warehousing Savings

Reduced material volume, high packing density, and low scrap rates can reduce shipping volumes by a factor of five or more compared to rigid, pre-formed high-temperature insulations

Simplified Inventory

Unlike rigid pre-forms such as pipe cover or board, the same Pyrogel® XT-E blanket can be kitted to fit any shape or design

Hydrophobic Yet Breathable

Pyrogel® XT-E repels liquid water but allows vapor to pass through, helping to prevent corrosion under insulation

Environmentally Safe

Aspen Aerogel’s high-temperature insulation is landfill disposable, shot-free, with no respirable fiber content
