Glass Fiber


Glass is an inorganic fiber, which is neither oriented nor crystalline. Glass fibers were one of the first "man-made" fibers, commercialized in the late 30's. Widely used as insulation (glass batts in home insulation and industrial insulation in mats and fabric form).

It is widely used in reinforcing thermoplastic composites in products from circuit boards to boat hulls. High temperature filtration is another high volume use. The ingredients normally used in making glass fibers are: silicon dioxide, calcium oxide, aluminum oxide, baron oxide, plus a few other metal oxides.
