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.

Applications

(1)Testing safety shoes with rubber soles used in foundries, kitchens, or metalworking plants.

(2)Evaluating casual leather shoes for thermal insulation in hot climates.

(3)Assessing sports shoes with EVA or PU midsoles for heat resistance during outdoor activities.

(4)Testing rubber boots and waterproof footwear for high-temperature work or hot surface exposure.

(5)Quality control of children’s shoes and school shoes for compliance with heat resistance standards.

(6)R&D of high-temperature resistant sole materials, such as heat-resistant thermoplastics or composites.

(7)Evaluation of industrial and military boots for thermal protection under extreme conditions.

Technical Parameters

Accessories

(1)Sand bath box

(2)Steel balls (5 mm, 4 kg total)

(3)Copper/copper-nickel thermocouple with copper disc

(4)Fixture for placing finished shoes

(5)Instruction manual

Test Procedures

(1)Preheat the sand bath to the specified test temperature (150℃ or 250℃).

(2)Fill the sand bath to a minimum height of 5 cm or place steel balls as the heat medium.

(3)Position the finished shoe on the fixture ensuring contact between the sole and sand/balls.

(4)Start the test and record the insole temperature over 30 minutes.

(5)Analyze the maximum temperature rise to evaluate the sole’s heat resistance.

Maintenance Information

(1)Clean the sand or steel balls and bath after each test to remove debris.

(2)Check the thermocouple and copper disc for wear and ensure accurate readings.

(3)Inspect the heating system and control panel periodically.

(4)Store the machine in a dry environment to prevent corrosion.

(5)Verify sand particle size and volume before each test to maintain consistency.
