borosilicate wafer glass/ 3.3 Borofloat Glass Wafer BF33

Product Overview

Description

thermostability borosilicate glass

Borosilicate glass is one of transparent colorless glasses, the wavelength is between 350nm to 2500nm, and the transimitance is more than 90%.

It's alkalifast, and the high temperature is up to 400°C,If course handling, the high temperature resiatant can reach 550°C.

 

1. Raw material: Borosilicate glass, Pyrex,  Optical glass.

2. Processing: by Molding, Grinding, Polishing.

3. Surface quality: optical surface quality and well controlled tolerance

4. Inside quality: clear and transparent, no mold marks, no inside bubble and dirts.

5. Great heat resistance performance,stable chemical property.

6. Working field :widely used in high-temperature observation windows, lighting (high-power lighting panel), appliances, laboratory containers, solar, lighting and other fields.

  This company produces of high borosilicate glass, with a good appearance, high temperature, resistance strong pressure, acid and alkali, high transparency, good quality, After cutting, grinding, polishing, milling,Tempered and so on process to complete.
