Thermal Insulation Test Apparatus

The thermal insulation test apparatus, also called heat insulation tester, is employed to test the high temperature resistance of the shoe sole made of rubber, polymer, and other materials.

Testing Method
Firstly, users shall heat up the sand box for the heat insulation testing equipment to the temperature of 150°C. The contact part of the upper and shoe sole shall be covered with sand. Afterwards, users can record the changes of the insole temperature within 30 minutes. The accuracy of the data can be ±0.5°C.
