Import Clear Quartz Rod — Buy in Bulk from Supplier in China

Clear quartz rod from Highborn International Company is a high-purity silicon dioxide material, typically drawn from fused silica with a minimum SiO2 content of 99.95%. The rods are available in diameters ranging from 5 mm to 50 mm and lengths up to 1,200 mm, with dimensional tolerances of ±0.1 mm. These rods are manufactured to maintain optical clarity and low iron content, making them suitable for precision optical and semiconductor applications.

The material exhibits a coefficient of thermal expansion of approximately 5.5 × 10⁻⁷ /°C and can withstand continuous operating temperatures up to 1,200°C without deformation. Its low thermal expansion and high thermal shock resistance are standard characteristics of fused quartz, not unique to this supplier. Surface finish is typically ground or polished to 10-20 microinch Ra, depending on end-use requirements. Variants may include rods with UV-transmitting properties, though this is not specified in the source data.

These rods are primarily purchased by manufacturers of semiconductor equipment, optical lens systems, and high-temperature laboratory apparatus. Buyers in Europe and North America often source them for use in quartz crucibles, wafer processing tools, and UV-transparent housings. Packaging is typically in rigid plastic tubes with foam inserts to prevent breakage. Trade terms are not specified, but FOB Lianyungang is common for this origin. Buyers should confirm exact dimensions and surface finish before ordering.

Highborn International Company is based in Lianyungang, Jiangsu Province, China, with a registered address at Rm.605, Huayin Office Bldg., No. 46 Chaoyang West Rd., Xinpu Dist. The supplier is classified as imported and holds a harbor trust tier, indicating verified export capacity but no public information on production scale or years in operation. There is no data on factory ownership, workforce size, or certifications.

The company operates as a trading entity sourcing quartz products from local manufacturers. No factory visit reports, third-party audits, or production capabilities are disclosed. Response metrics show no recorded activity, suggesting limited direct communication capacity. Buyers should treat this as a sourcing agent, not a manufacturer, and verify material origins and quality through independent testing before bulk orders.
