What are the main uses of mineral wool products?

1. In industry, mineral wool products are mainly used in the thermal insulation of industrial heating pipe networks and industrial furnaces, and the thermal insulation of ships and other vehicles. For example, in industrial boilers, power generation equipment, metallurgical furnaces, hot air or steam pipes, and ship compartments, mineral wool products are often used as insulation materials.

1. In the construction industry, mineral wool products are often used in the external thermal insulation of buildings, sound insulation filling materials for partition walls inside buildings, and sound-absorbing materials for ceilings in buildings.

1. In agriculture, mineral wool products are widely used in soilless cultivation of plants, replacing soil as the substrate for plant growth. Compared with other cultivation substrates, the mineral wool substrate has high water retention rate, good air permeability and relatively clean, and it is a kind of substrate with better performance in soilless cultivation.
