Frequently Asked Questions

What makes Borosilicate 3.3 glass different from regular glass?
Borosilicate 3.3 glass has a very low coefficient of thermal expansion, making it highly resistant to thermal shock and high temperatures compared to standard soda-lime glass.
What is the maximum temperature this glass can withstand?
For short-term usage (less than 10 hours), it can withstand up to 500°C. For long-term continuous usage, it is recommended for temperatures up to 450°C.
Is the glass surface suitable for high-precision optics?
Yes, it is manufactured using a unique micro-float process that ensures exceptional flatness, high surface quality, and low microroughness, suitable for industrial optics and sensors.
Can this glass be processed or customized?
Absolutely. The glass can be processed through cutting, grinding, polishing, drilling, sandblasting, coating, bending, and even printing to meet specific application requirements.
What industries commonly use Borosilicate 3.3 floated glass?
It is widely used in the chemical, pharmaceutical, food and drink industries, as well as in laboratory glassware, oven windows, and lighting components.
How is the glass protected during transport?
The product is securely packed in high-quality wooden crates to prevent breakage and ensure it arrives in perfect condition.
