Import Borosilicate Float Glass 3.3 — Buy in Bulk from Supplier in China

Qinhuangdao Scinan Specialty Glass Co., Ltd. supplies borosilicate float glass classified as 3.3‑grade, a material widely used for high‑temperature appliance panels and precision optical components. The product is supplied in standard sheet sizes such as 1150 mm × 850 mm, 1150 mm × 1700 mm and 1200 mm × 600 mm, with a thickness of 2.2 mm, and can be sized on request. The glass exhibits a density of 2.23 g cm⁻³ and meets the basic safety requirements for industrial use. Its refractive index of 1.47384 ensures reliable optical performance.

Borosilicate composition typically consists of roughly 80 % silica and 13 % boric oxide, granting a low thermal expansion coefficient of about 3.3 × 10⁻⁶ /K between 200 °C and 300 °C. In the industry, float glass of this type is produced with thicknesses from 2 mm to 12 mm, and light transmission values near 91‑92 % for 4‑5 mm sheets, matching the figures supplied. The material’s softening point around 820 °C and thermal shock resistance of 125 K make it suitable for environments with rapid temperature fluctuations. Standard processing includes cutting, edge grinding, drilling, coating and toughening, allowing adaptation to diverse end‑use requirements.

Typical buyers include manufacturers of household appliances, solar panel assemblers, optical filter producers and medical equipment makers who need reliable temperature resistance and optical clarity. The supplier offers flexible order quantities and can arrange FOB or CIF shipping, with payment by T/T or L/C as indicated. Prospective importers should request confirmation of any required certifications and verify that the custom dimensions and processing options are clearly documented before finalising the contract.
