The leading, largest, renowned Borosilicate glass tubes manufacturer and exporter in China, about 60MT output every day from 3 furances, guarantee the quantities and the quality for your need, Welcome for the inquiry and discussion of the business cooperation.
1) Available colors: dark blue, light blue, amber, light yellow, green, pink, purple, red and opaque blackú¼transparent black, gold champagne color new color.
2) Regularly stocked tubing size (diameter x wall thickness):
Heavy wall tubing :( ten colors)
25 x 4mm, 32 x 3.2mm, 32 x 4mm, 38 x 3.2mm, 38 x 4mm, 44 x 4mm, 51 x 4mm, 51 x 4.8mm (standard length of tubingú¦1220mm)
The neutral borosilicate glass tube is our main products which have an outer diameter of 4 mm to 300 mm, which can meet the different requirements of pharmaceutical packaging, daily necessities, electronic products, military industry and solar thermal power generation. USP Type I water-resistant neutral borosilicate glass, acid and water-resistant for grade I, strong resistance to rapid cooling and heat, chemical stability, mechanical strength and impact resistance are better than other glasses. At the same time, the material can be directly sealed with Kovar alloy, which is the core component of solar high temperature collector tube and the key material in military industry.
At present, the product quality of our company is stable, and the AI system has been realized in the productions line.

- > RESISTANCE TO CHEMICAL
Borosilicate glass is inert to almost all materials except hydroflouric acid (HF) phosphoric acid((H3Po4) and hot strong caustic solutions. Of these Hydroflouric acid has the most serious effect, even when it is present in PPM (parts per million) in solutions. Where as phosphoric acid and caustic solutions cause no problems when cold but at elevatrd temprature corrosion occurs. in case of caustic solutions upto 30% concentration can be handled safely at ambient temperature.
Under actual operating conditions, the effect of turbulence, and traces of other chemicals in the solution may increase of decrease the rate of attack. So it is not possible to give exact figures for corrosion by caustic solutions.
- > THERMAL PROPERTIES
Linear coefficient of thermal expansion
The coefficient of thermal expansion of borosilicate glass over the temperature 0 - 300�°C is 3.3 x 10-6/�°C. This is very low when compared with other glasses and metals. That is why, borosilicate glass is often called low expansion borosilicate glass.
Specific heat
Specific heat between 25C and 300C is average to be 0.233Kcal/Kg, C
Thermal Conductivity
Thermal conductivity is 1.0 Kcal/hr,mC. Over the permissible operating temperature range.
