Fiberglass Production Process


Fiberglass, or glass fiber wool, is a material made from extremely fine short fibers of glass. These fibers are produced by spinning or blowing molten glass (silica). In the manufacture of fiberglass wool, an adhesive binding solution is applied to hold the fibers together. These binders are also used as a coloring agent for the product. This coloring provides brand identification in the highly competitive insulation materials market.

Spent binder solution cannot be released into the local sewage systems, due to the color agents being difficult to neutralize. Spent binder solution is therefore collected from the production lines for recycling.

Vaisala K-PATENTS® Process Refractometer PR-43-GP is used to determine the amount of dissolved solids in the spent binder solution in order to control the quantity of fresh binder to be added.
