Borosilicate glass products are high-durability, heat-resistant, and chemically inert items primarily composed of silica and boron trioxide. Known for a very low coefficient of thermal expansion, they withstand intense thermal shock and chemical corrosion. Common uses include labware, high-end cookware, pharmaceutical packaging, and industrial equipment.

Key Characteristics and Properties

Thermal Shock Resistance: Withstands rapid temperature changes without cracking.

Chemical Durability: Highly resistant to water, acids, salt solutions, organic substances, and halogens.

Low Expansion: Minimal expansion/contraction during temperature fluctuations.

Physical Strength: Harder and more robust than soda-lime glass, reducing breakage.

Clarity: Offers excellent optical properties for laboratory and lighting applications.

Common Borosilicate Product Types

Laboratory Glassware: Beakers, flasks, test tubes, pipettes, and petri dishes.

Kitchen & Cookware: Baking dishes, coffee makers, teapots, and storage containers.

Industrial Components: Pipelines, sight glasses, and chemical processing equipment.

Specialty Items: Pharmaceutical vials, lighting fixtures (tubes), and art glass.
