DURAN® is widely used across industry, science, architecture and the arts thanks to its impressively broad range of technical assets. While it’s strong, durable and reliable in its physical properties, it also has the transparency and light transmission for very different areas of application.

Do you know that we are also able to upgrade our DURAN® glass tubing, rods, and capillaries? Thermal shock cutting, fire polishing, bending, joining of glass parts as well as sawing, grinding, drilling, or sandblasting are only some of our capabilities in our further processing portfolio.

The technical ability to take on any task

Hydrolytic resistance

DURAN® is reassuringly stable in highly corrosive and hazardous materials environments due to the high hydrolytic resistance (class HGB1) of the material and properties such as class S-1 acid resistance.

Outstanding transmission

DURAN® is the ideal base material for transparent tubing and containers, thanks to consistently stable transmission from UV-A into IR range.

Thermal shock resistance

The ability of DURAN® to withstand high temperatures and temperature fluctuations makes it suitable for contact with open flames or in other extreme working environments.

Impressive electrical properties

DURAN® is well-suited to high-voltage electrical applications thanks to strong electrical insulating properties and high dielectric strength.
