High borosilicate glass

Borosilicate Float Glass3.3(BG33)

Our 3.3 borosilicate glass is extremely versatile too – you can use it for almost any purpose imaginable; such as microscope slides and petri dishes; kitchenware items like oven-proof baking dishes; art projects like stained-glass windows.

The possibilities are endless! Its lightweight yet strong construction allows for easy transport between workspaces so you can take your creations wherever they need to go.

And thanks to its crystal clear transparency, light passes through beautifully with no distortion whatsoever - making sure whatever design you come up with looks perfect every time! 


Borosilicate Float Glass3.3 Introduction

This revolutionary glass is made of borosilicate, a special material that combines strength and durability with an extraordinarily high heat resistance.

Whether it's functional or decorative, this magnificent material will make any project look great while helping protect against extreme temperatures up to 500°C (932°F). And because of its excellent thermal shock properties, it won't cloud over time from frequent temperature fluctuations either! 


Borosilicate float glass 3.3 is a special glass material with low expansion rate, high emperature resistance, high strength, high hardness, high light transmittance and high chemical stability.

Because of its excellent performance, it is widely used in household appliances, environmental engineering, medical technology, safety protection and other fields, especially in the field of household appliances, borosilicate float glass 3.3 is widely used as the panel and inner tray of ovens and microwave ovens.

In addition, because the hardness of borosilicate float glass 3.3 is 8-10 times that of ordinary glass, it is also used as bulletproof glass by many customers.

Product Features

Great heat resistance performance

Stable chemical property

High light transmission

Various thicknesses for you to choose

Wide optical application


Application field

Borosilicate 3.3 serves as a material of true function and wide applications:

1).  Household electrical appliance (panel for oven and fireplace, microwave tray etc.);

2).  Environmental engineering and chemical engineering (lining layer of repellence, autoclave of chemical reaction and safety spectacles);

3). Lighting (spotlight and protective glass for jumbo power of floodlight);

4). Power regeneration by solar energy (solar cell base plate);

5). Fine instruments (optical filter);

6). Semi-conductor technology (LCD disc, display glass);

7). Medical technique and bio-engineering;

8). Safety protection (bullet proof glass)


High borosilicate 3.3 glass is high-temperature resistant glass, heat-resistant glass and temperature difference resistant glass.

The linear expansion coefficient is 3.3 ± 0.1 × 10-6 / K, is a glass with sodium oxide (Na2O), boron oxide (b2o2) and silicon dioxide (SiO2) as the basic components.

The content of boron and silicon in the glass composition is relatively high, namely, boron: 12.5 ~ 13.5%, silicon: 78 ~ 80%.

The expansion coefficient will affect the stability of glass.

The expansion coefficient of borosilicate 3.3 heat-resistant glass is 0.4 times that of ordinary glass.

Therefore, at high temperature, borosilicate 3.3 heat-resistant glass still maintains excellent stability and will not crack or break.

The long-term working temperature of borosilicate 3.3 heat-resistant glass can reach 450 ℃, so it is often used as the microwave oven panel.

At high temperature, borosilicate 3.3 heat-resistant glass can not only work normally, but also maintain high permeability, which is convenient for users to observe the internal food state.

Q:I have seen the prices of custom size aquariums and thought it might be cheaper to do it myself. Does anyone know where I can get the glass or acrylic to construct a fish tank? Can I just get it at Home Depot or something?
no tempered glass will shatter in to peaces if a rock or something hits it cuz it dosent have pvb like laminated glass dose so laminated glass would be better cuz if a rock hits it it will just crack and not shatter so if i had to make a fish tank i would chouse laminated cuz it dosent shatter i mean would you relly want your fish to die cuz your fish tank shatters and if it cracks at lest you have time to get your fish out and have time to get your fish tank out of a room or where ever it is out befor it makes a mess and would you relly want to clean up millions of pices of glass hope this helps
Q:Double 15 steel laminated glass how much money side
How much area do you have? Architectural glass
Q:What is 5 + 12A + 5 transparent glass
5 is the thickness of the glass, 12A is the width of the hollow barrier, and the distance between the two glass, both in mm (mm) as a unit.
Q:Would you like to make windows white glass is good or green is good? That expensive Looks upscale? Thank you!
Rewan glass: Rewan glass is heated by the plate glass to soften the mold in the mold, and then annealed by the curved glass. Rewan glass in some of the high-level decoration in the frequency of getting higher and higher, need to be scheduled, no cash.
Q:Would like to ask Shaanxi master film industry architectural glass film / insulation film / decorative film how ah, no one has ever let them paste the film?
They have magnetron sputtering film
Q:What is the material of the protective film in the middle of the glass
At present, the glass raw materials of tempered glass film generally have these brands. High end: Corning & Schott. End: Asahi Glass. In the low-end: the board of the glass and Luo glass. Looks like the brand is different? Jeanswest and Reeve's difference? Not also, the material is different.
Q:What is the difference between the span on the architectural glass and the width of the glass?
Width, refers to the size of a single piece of glass, that is, between the size of the two sides of the box
Q:Curtain wall energy conservation generally use what material
Channel-type double-layer breathing glass curtain wall. Super energy saving.
Q:The state is the number of buildings above the tempered glass
7 floors and 7 floors above the building outside the window;
Q:What is the coating of the glass coating?
What kind of glass did you ask? Automotive glass? Optical glass? Architectural glass? Different glass coating is not the same.
