Mineral wool is any fibrous material formed by spinning or drawing molten mineral or rock materials such as slag and ceramics. [1] Applications of mineral wool include thermal insulation (as both structural insulation and pipe insulation), filtration, soundproofing, and hydroponic growth medium.
The expanded material is a brilliant white, due to the reflectivity of the trapped bubbles. Unexpanded ("raw") perlite has a bulk density around 1100 kg/m 3 (1.1 g/cm 3), while typical expanded perlite has a bulk density of about 30–150 kg/m 3 (0.03–0.150 g/cm 3). [2]

Given the linear density and weight the yarn length can be calculated; for example: l/m = 1693 × l m /Nec × m/kg, where l/m is the yarn length in metres, l m /Nec is the English cotton count and m/kg is the yarn weight in kilograms. The following length units are defined. Bundle: usually 10 lb (4.5 kg)

Mineral bonded wood wool boards (WW boards) are building boards made of wood wool fibres, water and the binding agents cement, caustic magnesia and gypsum. Mineral bound wood wool boards are used in a wide range of applications, e.g., thermal insulation , acoustic insulation , indoor decoration, etc.
