ANTGLASS supplies and processes Domestic Borosilicate 3.3 Glass for optical, electronic, laboratory and industrial components made to customer drawings.
Material Overview
Domestic Borosilicate 3.3: Standards-defined material family; Flat Borosilicate 3.3 Float Sheet: Domestic borosilicate 3.3 sheet; High Borosilicate Glass 3.3: Domestic borosilicate 3.3 sheet. The material system is described as Standards-defined material family. Selection begins with the exact grade, wavelength or optical function, thermal and chemical environment, starting form, finished geometry and inspection method. The material record is kept separate from the finished-part drawing so that grade data and manufacturing requirements remain traceable.
Applications associated with this material include Cost-effective thermal windows, tubes, plates, industrial components, Heat-resistant windows, sight glass. ANTGLASS uses the approved material and drawing to manufacture blanks and finished parts rather than treating a published material property as a universal component guarantee.

Design Rules for a Manufacturable RFQ
- Define thermal cycling, gasket or sealing contact and the unsupported clear span.
- Dimension critical surfaces, edges, holes, slots and datums separately on the drawing.
- Identify optical, sealing, bonding, coated and cosmetic zones before quotation.
- Match inspection methods to the functional tolerance and surface requirement.
- State prototype and production quantities together with cleaning and packaging needs.
Quality Risks and Inspection
Control edge damage, sealing contact, thermal gradients and clamp loading. Material data does not replace validation of the complete pressure, thermal or chemical assembly.

Material Comparison and Alternatives
Compare Domestic Borosilicate 3.3 Glass with Fused silica for lower CTE and higher temperature, soda-lime for lower cost, aluminosilicate for strengthening.. Substitution should preserve the functional wavelength, refractive or spectral behavior, thermal expansion, temperature range, chemical durability, mechanical behavior, starting form and component cost.
