Import Borosilicate Colored Glass Tube — Buy in Bulk from Supplier in China

The Borosilicate colored glass tube offered by Huailai Tianyuan Special Type Glass Co Ltd is manufactured from borosilicate glass, a material known for its low thermal expansion and durability. It is supplied in a palette of colors including dark blue, light blue, amber, light yellow, green, pink, purple, red and opaque black, allowing visual customization for diverse projects. The glass composition provides resistance to thermal shock and chemical corrosion, making the tubes suitable for environments with rapid temperature changes. Each tube is lightweight yet retains structural strength for handling and transport.

Borosilicate glass typically exhibits a coefficient of thermal expansion around 3.3 × 10⁻⁶ /°C, which contributes to its stability under heating and cooling cycles. Industry practice for decorative or laboratory tubing uses wall thicknesses of 2 - 3 mm and outer diameters ranging from 10 to 30 mm, dimensions that the supplier can accommodate within standard tolerances. The transparent variants offer clear visibility of internal contents, while the coloured options provide aesthetic appeal without compromising performance. Standard packaging involves protective crates that prevent breakage during shipping.

Typical buyers include artists, laboratory technicians and manufacturers of decorative hardware who require both functional and visual qualities. The supplier states flexible minimum order quantities and provides ISO and SGS certifications to confirm compliance with international quality standards. Shipping terms such as FOB or CIF can be arranged according to the importer’s logistical preferences.
