Q: How to judge the quality of rock wool: Burning performance: Combustion performance refers to all the physical and chemical changes that occur when the building material is burned or in case of fire. This performance is caused by the fire and flame propagation of the material surface, heat, smoke, carbonization, weight loss, and toxicity And other characteristics to measure. The burning performance of the products of rock wool products is zero.
