Thermal Load Testing Apparatus
Category：Flammability Tester
Introduction
The Thermal Load Testing Apparatus for Insulation Rock Wool is designed for evaluating the thermal load performance and heat-load shrinkage temperature of rock wool and mineral wool insulation products. It provides precise heating control, accurate measurement of thermal deformation, and reliable assessment of material performance under high temperatures. The device is widely used in research, quality control, and production testing of insulation materials.
Application
This apparatus is widely used for:
(1) Testing thermal load and heat-induced shrinkage of insulation rock wool and mineral wool boards, blankets, or panels.
(2) Evaluating fire resistance and heat stability of insulation materials used in construction and industrial applications.
(3) Research and development in building materials for energy-efficient and fire-safe insulation.
(4) Quality control in rock wool manufacturing plants for batch verification of thermal performance.
(5) Educational and testing laboratories for materials science and civil engineering studies.
(6) Safety and regulatory compliance testing of insulation materials according to national and international standards.
Tested products include rock wool boards, batts, slabs, blankets, and composite insulation panels.
