Kapton's relatively high thermal conductivity at very low temperatures, together with its good dielectric qualities and its availability as thin sheets, have made it a favorite material in cryogenics, as it provides electrical insulation at low thermal gradients. Kapton is regularly used as an insulator in ultra-high-vacuum environments due to ...
Chemical structure of Kapton, a polyimide. Polyimide (sometimes abbreviated PI) is a polymer containing imide groups belonging to the class of high-performance plastics.With their high heat-resistance, polyimides enjoy diverse applications in roles demanding rugged organic materials, such as high temperature fuel cells, displays, and various military roles.
Multi-layer insulation (MLI) is thermal insulation composed of multiple layers of thin sheets and is often used on spacecraft and cryogenics. Also referred to as superinsulation, [ 1 ] MLI is one of the main items of the spacecraft thermal design , primarily intended to reduce heat loss by thermal radiation .

This is a list of insulation materials used around the world. Typical R-values are given for various materials and structures as approximations based on the average of available figures and are sorted by lowest value. R-value at 1 m gives R-values normalised to a 1 metre (3 ft 3 in) thickness and sorts by median value of the range.
Insulation is set to become increasingly important in coming decades, as Britain seeks to limit carbon emissions. Scientists invent environmentally friendly insulation made of popcorn Skip to main ...
Vespel is commonly used as a thermal conductivity reference material for testing thermal insulators, because of high reproducibility and consistency of its thermophysical properties. For example, it can withstand repeated heating up to 300 °C without altering its thermal and mechanical properties.
The materials science segment— to be named Dow Chemical Company—consists of DuPont's Performance Materials unit, together with Dow's Performance Plastics, Materials and Chemicals, Infrastructure and Consumer Solutions, but excludes Dow's Electronic Materials business. Combined revenue for this branch totals an estimated $51 billion.
