Compliance with standards: Complies with the test standard requirements of GB/T11835 "Test Method for Thermal Load Shrinkage Temperature of Mineral Wool and Products".
Product Overview: Suitable for rock wool, slag wool and glass wool and their products, not suitable for aluminosilicate wool and its products. Under a fixed load, the sample is heated at a certain heating rate to reach the specified thickness shrinkage rate. Through calculation, the thermal load shrinkage temperature is obtained by interpolation
