If there is any specific requirement towards the parameters or package, we can discuss in email for we are flexible towards the cooperation but loyal to the cooperation.

Here we are mainly talking about the use of 3A in insulating glass.

Let me talk about what is hollow glass:
Insulating glass is a glass product in which two or more pieces of glass are evenly spaced for effective support and bonded and sealed around the periphery to form a dry gas space between the glass layers. The main materials are glass, aluminum spacers, angle bolts, butyl rubber, polysulfide rubber, and desiccant.

Molecular sieve (also called as synthesized zeolite) is a kind of silica-aluminates with micro-porous crystal. It is a frame-work which is constructed by SiO₂ and Al₂O₃. Molecular sieve has very similar aperture value (only several A) and large surface area. There are relevant positive ions in its lattice to balance the negative ions in the crystal frame. Different molecular sieves have different shapes and different aperture values. We could separate different kinds of molecular by selectively using different molecular sieves. Water is a sort of polar molecule, molecular sieve type A has dramatic affinity for water. For the above reasons, molecular sieve is considered as the most ideal desiccant. The molecular sieve here mentioned is type 3A which is only for adsorbing water. The water adoption depth of molecular sieve 3A is above several dozen times higher than other any other applicable desiccants.
