Mineral wool and the related products are light, durable, non-flammable, non-corrupt, and free from insects. It is an excellent material for heat insulation and sound absorption. Mineral wool is a cotton-like staple fiber made from a silicate melt.
 
The earliest mineral wool obtained from the crater of Hawaii was called "Far's hair." Those that use metallurgical slag or fly ash as their main raw materials are called slag wool; those that use rocks such as basalt as their main raw material are called "rock wool". The raw materials are crushed to a certain particle size, and add additive for the ingredients. Then the ingredients are melted by furnace, filled into cotton, and packaged.
 
There are three kinds of cotton-making processes: injection method, centrifugal method and centrifugal injection method. Mineral wool and binders can be processed into various mineral wool products after forming, drying and curing.
