The thermal conductivity of a material is a measure of its ability to conduct heat. It is commonly denoted by k, λ, or κ and, in SI units, is measured in W·m−1·K−1. It quantifies the proportionality b

…a lightweight filler in composite materials such as syntactic foam and lightweight concrete. Microballoons give syntactic foam its light weight, low thermal conductivity, and a resistance to compressive stress that far exceeds that of other foams. These properties are exploited in the hulls of submersibles and deep-sea…
Exhaust system components with ceramic coatings having a low thermal conductivity reduce heating of nearby sensitive components.
