The concept of microporous insulation was originally developed in the 1940s. It was first designed to be employed in nuclear, space and aerospace applications because of its ability to outperform conventional insulation systems with less material and weight in less usable space. Initially considered to be too expensive across the board for use in more price sensitive commercial, industrial and automotive applications, new formulations and manufacturing processes developed by ThermoDyne have produced alternate forms of the insulation and made it available to various other markets without substantially reducing the performance.

Microporous Insulation works for the industrial marketplace where there are considerable gains to be found in its exceptional thermal management abilities. In applications as small as hobby kilns to large operations like aluminum carbon bakes, the presence of a microporous layer in place of or within a composite lining can save/retain as much as 30% or more of the energy normally lost in linings without microporous materials. This form of conservation translates directly to overall energy cost savings since less heat energy loss also means that less energy is required to keep the application at its desired temperature and conditions. Microporous materials are also ideal for reducing the re-heat time associated with molten metal applications and can be used to increase the distribution and homogeneity of heat throughout, both reducing the risk of isolated hot spots and improving product uniformity.

Thermo Dyne materials are cost-effective enough for automotive applications. Many of the new exhaust systems have become extremely hot and require extensive insulation and heat shielding. The lightweight nature and improved thermal efficiency of microporous material makes it ideal for automotive applications where manufacturers and suppliers must increasingly conform to more rigid standards of space and weight conservation in vehicle designs.

Microporous insulation has been used in the space exploration and aerospace industries for nearly 50 years. It is beneficial in these environments because its extraordinarily lightweight and relatively space-conscious construction allows it to be used more sparingly than conventional insulations without compromising thermal performance. In applications where every unnecessary ounce carried by an aircraft or spacecraft equates to a loss in overall performance, microporous insulation still remains the undisputed solution in the industry. In addition, at the lower pressures of commercial flight altitude and above there is an additional performance gains that other materials do not experience.

In addition to light-weight and space saving advantages, ThermoDyne's microporous insulation options provides the highest degree of thermal protection and flexibility currently available in the market. As experts in thermal management, our engineers provide the technical support you need when specifying our standard insulation products, or designing a specific solution to fit your application or engineered system. Roughly 90% of what we produce are engineered systems.​
