stone wool is made of basalt and other natural Stones. The insulation Stonewool board is produced by melting raw materials and making melted raw materials into fibers at high temperature, and an appropriate amount of binder is added into the fibers. Insulation Stonewool board is widely used in ships, electric power, construction, metallurgy and other industries. Insulation Stonewool board has good sound insulation and heat insulation performance.

     Insulation Stonewool board has stable quality and has no harm to human body. It is an insulation material for industry insulation and building insulation, and it is also an excellent sound-absorbing and filtering material.
     1. Thermal conductivity: The thermal conductivity of stone wool products changes with the bulk density and temperature. This is mainly because stone wool products are a material with a large porosity. And the heat transfer amount by conduction, convection, and radiation will change when density of stone wool changes and environment temperature changes. 
     2. High working temperature: Insulation Stonewool board will not change under 600℃ for long time.
     3. Non-combustibility: Whether in the construction industry or other thermal insulation fields, the non-combustibility of materials is a very important indicator.
