BOROFLOAT33 is highly resistant to corrosion by water, strong acids, bases, and organic materials. Especially suitable for chemical applications, such as reactor and plant observation mirror. Another area of application is medical and analytical technology. The composition of the glass container is stable and has little effect on the measurement, since water and acid only lead to leaching of a very small number of ions from the glass. BOROFLOAT33 is less dense than sodium-calcium float glass. BOROFLOAT33 has already demonstrated its strength in many traditional applications.BOROFLOAT33 can be used to make laminated glass systems that perform the same function with significantly less weight than conventional laminated glass systems (e.g. bulletproof glass). Today, it continues to expand its presence in emerging and technically complex specialty glass applications such as biotechnology, microelectronics and photovoltaic.

FAQs:
A: We look at ourselves as the piezo wafer specialist. We are the very first to work with Single Crystal Quartz in China about 30 years ago. Then gradually we step in the field of LiNbO3, LiTaO3, Quartz glass, LGS, CTGS etc. Especially, if you are looking for a piezo quartz supplier, we are the ultimate choice! We export millions of quartz blanks each year because we master the AT, SC and IT cuts with superior angle precision.
A: Yes, of course. We can fabricate as per your request. In addition, we are so experienced with piezo wafers that we can provide you relevant suggestions if you are not 100% sure about your choice. Besides, we do have some standard wafers in stock, please check with us.
A: Yes, we would suggest you go with the courier agent you are most familiar with (DHL, FedEX, UPS etc.). We can ship via your account. And, of course, we will pack the products safely in acceptable size to help you save the shipping cost. If you need us to take care of the freight, it’s also not a problem. We also have good discount with the international courier companies.
A: The wafer products are fragile and sometimes expensive. The last thing, as the manufacturer, we want to see is the products we make were damaged during courier. As a result, we will pack the wafers adequately and put them in a proper carton filled with buffer sponge. However, accidents are inevitable sometimes. So, please follow the “Acceptance check” steps shown in the drawings below. If the unwanted happened, we will either give the replenishment or refund if you follow the checking steps.
A: Sure. Factory inspection is important for large quantity purchase and long-term cooperation. Face to face discussion is what we mostly confident with. During the past years, big names around the world have witnessed our progress in factory build-up. These days, due to the Covid-19 pandemic, we also had the experience of videoconferencing with global buyers.
