Shoes Thermal Insulation Tester
The Shoe Sole Heat Resistance Tester is designed to evaluate the thermal insulation and heat resistance performance of finished footwear soles. By simulating exposure to high-temperature surfaces using sand or steel balls as a heat medium, the tester provides objective measurements of temperature rise at the insole, ensuring the footwear meets safety requirements for hot environments.
