The Universal Selection Source: Plastics & Elastomers


Thermal Insulation

The thermal insulating capacity of plastics is rated by measuring the thermal conductivity. The values are reported in W/m.K. The lower the value, the better the thermal insulation.

Thermal conductivity of plastics is generally measured by ASTM C177 and ISO 8302, using guarded hot-plate apparatus.
