Frequently Asked Questions (FAQs) for B2B Buyers of borofloat glass sheet

• 1. How do I select the right thickness of borofloat glass for my application?
  Choosing the appropriate thickness of borofloat glass depends on the specific requirements of your project, including mechanical load, thermal resistance, and transparency needs. Generally, thinner sheets (e.g., 0.7 mm to 2.0 mm) are suitable for applications requiring high transparency and lower mechanical stress, such as display cases and laboratory equipment. Thicker sheets (5 mm and above) are ideal for high-stress environments like industrial machinery windows or medical devices. Always consider the operational environment and consult with suppliers for recommendations based on your application’s demands.

• 2. What are the key benefits of using borofloat glass over standard glass?
  BOROFLOAT® glass offers several advantages compared to traditional glass, including superior thermal resistance, high chemical durability, and exceptional optical clarity. Its ability to withstand extreme temperature fluctuations makes it ideal for applications like laboratory equipment and industrial sight windows. Additionally, its low thermal expansion coefficient ensures minimal distortion, enhancing the performance of optical devices. This combination of properties ensures that borofloat glass is a preferred choice for demanding applications across various industries.

• 3. What is the typical lead time for ordering borofloat glass sheets internationally?
  Lead times for international orders of borofloat glass sheets can vary significantly based on factors such as order volume, thickness, and supplier location.
