Gas-permeable glass "porous glass" (porous glass)
Nano-sized holes allow gases to pass through, and separation can be achieved using adsorption properties. Active in separation and catalysis!
Our company has over 40 years of experience in the manufacturing of "porous glass," which has the property of allowing gases to pass through, and it is used both domestically and internationally. The pore diameter ranges from 4 to 70 nm, making it suitable for applications such as separation filters and catalyst supports, and it is possible to adjust the pore size to selectively separate specific substances. (Pore sizes larger than 70 nm can also be discussed.) 【Examples of Applications】 ■ Partial porosity (porous glass can be applied to only a portion) ■ Superfluid film flow containers (making the outer surface of glass porous) ■ Porous glass coated with graphene (providing conductivity while maintaining breathability) *We can accommodate various other needs, so please feel free to contact us. *For more details, please download the PDF or contact us directly.
