Product Description

The tubes are with diameter ranging from Φ9mm to Φ160mm and wall thickness from 1mm to 5mm,The glass can be adapted to various products, like glass instrument tubes, domestic glass ware, glass rod, chemical tubes, medium-high temperature Solar thermal tubes, rough solar vacuum tubes

The adaptability of glass allows it to provide target solutions for many related industries

1. High Borosilicate Glass in Daily Usage

High borosilicate glass is considered to be the healthiest and most safe daily usage glass for it doesn't contain or generate any matters harmful to the body in usage. It is also featured by anti-temperature difference, non-bursting rate, good gloss, etc.

2. High Borosilicate Glass in Laboratory

Highly resistant to thermal shock and heat; resistant to water, strong acids, alkali and saline solutions.

3. High Borosilicate Glass in Lighting
High optical and cosmetic quality, no extra reflection and refraction. Tight geometric tolerances allows for stable manufacturing process and easy assembly. Especially low thermal expansion, high resistant to thermal shock and high chemical resistance make it optimally suitable for use in adverse conditions.

Our High borosilicate glass tubes has feature of low expansion rate, high temperature resistance, high strength, high hardness, high light transmittance, and high chemical stability. We are source tube supplier for famous brands like Starbucks, Xiaobaixiong, and Wuliangye. The high quality has won us unanimous favorable comments from customers.
