Shoe Heat Insulation Sand Bath Tester
Shoe Heat Insulation Sand Bath Tester is a professional testing instrument designed to evaluate the thermal insulation performance of footwear under high-temperature conditions. The instrument simulates extreme heat environments by heating a sand bath to a specified temperature and measuring the temperature change on the insole surface after the footwear sample is exposed for a certain period. It is mainly used to assess the heat insulation capability of shoe soles and upper structures, providing reliable test data for footwear safety evaluation, quality control, and product development.
Application
(1) Footwear Quality Control: Used by shoe manufacturers to verify the thermal insulation performance of different production batches and ensure products meet design requirements.
(2) Protective Footwear Testing: Suitable for evaluating heat resistance performance of industrial safety shoes, protective shoes, and footwear used in high-temperature working environments.
(3) Product Development and Material Research: Helps manufacturers compare the influence of different sole materials, insulation layers, structures, and designs on thermal protection performance.
(4) Laboratory Testing and Certification: Used in footwear testing laboratories and third-party inspection organizations for compliance evaluation.
(5) Performance Comparison Testing: Provides test data for comparing thermal insulation performance between different footwear models, materials, and suppliers.
