Introduction to fiberglass wool insulation

It is made of glass balls or waste glass as raw materials by high-temperature melting, drawing, winding, weaving and other processes, the diameter of its monofilament is a few microns to more than 20 meters of microns, equivalent to 1/20-1/5 of a hair, each bundle of fiber precursor is composed of hundreds or even thousands of monofilaments. Glass fiber is usually used as a reinforcing material in composite materials, electrical insulating materials and thermal insulation materials, circuit substrates and other fields of the national economy.
