Product Description:

Borosilicate Float Glass3.3(BG33)

Product 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.

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.


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!

Q:Would you like to make windows white glass is good or green is good? That expensive Looks upscale? Thank you!
Tempered glass Tempered glass, also known as tempered glass, is heated to a certain temperature after the rapid cooling method, or chemical methods for special treatment of glass. Tempered glass is characterized by high strength, tempered glass bending strength, impact resistance than ordinary flat glass 3 to 5 times higher. Safety performance, there is a uniform internal stress, broken network was cracked. Mainly used for doors and windows, partition walls and cabinet doors. Tempered glass is still resistant to acid and alkali. The general thickness is 2-5 mm. Its size is 400 mm x 900 mm, 500 mm x 1200 mm.
Q:How is the sun room insulated?
Awning. Shade cloth Shade sun foil. 4. Shade bamboo curtain. Folding awning advantages: winter removed, the sun came in. Disadvantages: trouble, high cost. Shade cloth advantages: free to install. Disadvantages: with magnetic buckle, asked the sun room material, metal class. Shade sun foil Advantages: paste up do not have to back and forth is not cumbersome. Disadvantages: a little light block, the room was dark. Shade bamboo curtain advantages: low cost, simple, the original ecology. Disadvantages: ash, bad care.
Q:Frosted glass film can not be attached to the wall
Frosted glass film can be attached to the wall, as long as the wall is smooth and can be affixed. Matte film is broadly divided into ordinary glass matte film and touch screen matte film, is the object from the surface smooth into the surface is not smooth.
Q:photographing modern buildings
This will depend on what camera your using. With a APS-C sized DSLR an ultra wide angle lens like a Canon 10-22mm or Nikon 12-24mm. If using a full frame camera a wide angle lens in the area of 14-24mm or a tilt shift lens. The tilt shift lens would be best. Both Canon and Nikon make them. Nikon call them PC lenses. Of course a large format camera would be best because of their ability to tilt and shift the film plane.
Q:What is the role of glass in architecture?
Window - lighting, insulating glass insulation. Glass partition, glass door - partition space without blocking the line of sight,
Q:Effect of Moisture Content on Automotive Laminated Glass Sheet
You said that the car laminated glass should be PVB film PVB film moisture content: the mechanical strength of laminated glass depends largely on the moisture content of PVB film, but not the film moisture content as low as possible, in the production of laminated glass, film moisture control is very important, when the water The film is too small, the film is very brittle, the strength of the laminated glass decreased significantly, and when the impact of the glass can be punctured, when the moisture content for a long time, the film and the glass between the adhesion decreased and lead to the use of degumming and foaming, The moisture content of the film for architectural glass is between 0.3% and 0.6%. In this range the film is most tightly bonded to the glass. Detection of PVB film moisture content can be used crown moisture detector
Q:What are the types of glass?
Rewan glass: Rewan glass is heated by the plate glass to soften the mold in the mold, and then annealed to make the surface of the glass. Rewan glass in some high-level decoration in the frequency is getting higher and higher, need to be scheduled, no cash.
Q:I have a chinese water dragon. He is still a baby but I'm looking to build him a bigger cage as he will grow to possibly three feet in length. I've searched the net for ideas on his cage and I'd like to use glass or plexi-glass on the sides and front of the cage. Even though I've looked at all the youtube videos I can find and any free plans I can find, I can't find a good way to build doors with glass, or plexi-glass, in them. I might just go with a sliding door but I'd prefer a door or two similar to a cabinet door. The opening is most likely going to be about 4 feet high. I also can't figure out how to attach the side, glass/plexi-glass, panels.I have basic tools but I don't consider myself a great carpenter. In other words, it needs to be simple.Any suggestions/help would be wonderful.
I would go with the plexi. That way you could make a wooden frame (or metal if you wanted) and then just drill the plexi (very slowly as to not crack it) and then screw it into the frame that you have made. Once you have that done you can focus on the doors. I would suggest making them in the same fashion. Once you have everything assembled you should seal it up. For this i suggest using "aquarium silicone" (use this because it is animal safe). You can get it any Lowe's or Home Depot (it should be near the paints and glues). *NOTE* -If you plan on building this way it is very important to remember that you need air holes or screening so the animal can breathe. For this you can either drill more holes in the plexi, or use some sort of screen for the roof- I hope this has given you some more ideas on how to make an enclosure that will not only house your larger animal, but also look decent doing it :)
Q:Korea architectural glass film brand
Now a lot of Korean film is actually domestic to do, but South Korea's raw materials, the specific brand about to know
Q:Domestic architectural glass insulation film which brand is good
Do you say domestic brands? I do not recommend posted domestic brands, it is best to choose foreign brands, such as iUQE, ten years warranty, will not release harmful substances.
