The chemical composition is glass, and the surface is generally aluminum foil. Glass fibers can be divided into two major groups according to their geometry: continuous fibers used in yarns and textiles, and the discontinuous (short) fibers used as batts, blankets, or boards for insulation and filtration. The remaining 2% organic content is generally a thermosetting resin binder (an adhesive) and a little oil. Because of the production techniques, the wool pack contains particles of unfibreised materials called shot. Chemical composition requirement for feldspar: Al2O3>15%, SiO2<70%, Fe2O3<0.3%, R2O>10%. Glass wool is a furnace product of molten glass at a temperature of about 1450 °C. Glass wool belongs to a category of glass fiber and is an artificial inorganic fiber.

Acute toxicity - dermal trailer In this research, glass wool fibers with a thickness of 5–8 µm were mixed in a dense-graded AC mixture together with asphalt binder and aggregates. In assessing the health evidence concerning man-made mineral fibers, the chemical composition, surface activity, durability, and size of fibers have to be taken into account. The level of borate in glass wool is typically 4 to 7% B 2 O 3. Data are for constituents: Biosoluble glass mineral wool - Not applicable. The process traps many small pockets of air between the glass, and these small air pockets result in high thermal insulation properties. Glass wool is a fiber-like material that melts glass to form cotton. It has been discovered that the level of boron in the glass used for the manufacture of loose-fill glass wool can be substantially reduced without degrading thermal performance. It is generally use to make flame proof, water proof fabrics or to make the body of sports car and parts of crafts. 0–1 Trace . Sodalime or soft glass
