Product DescriptionThe 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 tubesProduct ApplicationThe
adaptability of glass allows it to provide target solutions for
many related industries1. 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 LaboratoryHighly resistant to thermal shock and heat; resistant
to water, strong acids, alkali and saline
solutions. 3. High Borosilicate Glass in LightingHigh
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.Product AdvantagesOur 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.Product ParametersPhysical PropertyNo.Physical
