There are 3 main categories of insulators used in spacecrafts:
1. foams: organic and inorganic;
2. fibrous insulations: for internal and external insulation and for high temperature environments
3. multilayer insulations (MLI): layers of radiation reflecting shields.
Properties, thermal behaviour and application areas of the insulation materials used in spacecrafts are detailed in this Part 7.
