Borosilicate Glass is the cornerstone for all heat-resistant glass applications. Boron content of glass differs from 1 to 22.5% depending on the quality and type of the glass.

Borates also enter into glass production of fiberglass for insulation, fabrics and reinforcement, and also as specialty glass products for household, laboratory, optical, heat resistance and many other uses. Boron’s effect on glass was initially established in the late 1800’s and the late 1930’s its usefulness in fiberglass was also well recognized. By the 1940’s fiberglass, high durability and performance glass and speciality glass were being made in large continuous furnaces.

In general, boron considerably reduces the thermal expansion of glass, provides good resistance to vibration, high temperatures and thermal shock, and improves its toughness, strength, chemical resistance and durability. It also greatly reduces the viscosity of the glass melt as it is being made. These features, and others, allow it to form superior glass for many industrial and specialty applications.
