|
| BOROFLOAT flat
glass has excellent optical characteristics because of the high quality
resulting from the float glass process. BOROFLOAT is a excellent equivalent
to PYREX, this opens up new applications for borosilicate flat glass
which has proved itself over time in laboratories, chemical processing
plants, and in the home appliance and lighting industries. BOROFLOAT
flat glass is highly resistant to water, neutral, acidic and saline
solutions, as well as to chlorine, bromine, iodine and organic substances.
Even over long periods of time and at temperatures above 100C, BOROFLOAT
exceeds the chemical resistance of most metals and other materials.
Maximum long term operating temperature is 450oC. |
Applications:
|
|
| Precision engineering,
optical applications, home appliances, environmental technology, sewage
treatment technology and lighting. Flatness, parallelism, cutting tolerances,
roughness, cosmetic defects and visual inspection all conform to the
specifications to be agreed upon by Precision Glass & Optics and
the customer. |
