Molecular Sieve (Desiccant)
Molecular Sieve (Desiccant) 3A or 4A
Insulating glass molecular sieve made from zeolite and clay mineral, porous solid structure,light yellow/white ball particles.
Features：
1). High hardness and smooth surface, high abrasion resistance, no peeling, no break.
2). Only adsorb moisture, don’t adsorb Nitrogen and Argon.
3). Good temperature stability.

Note：
1). In filling process, try to shorten the time of molecular sieve in air;
2). After opening package for 70 minutes where exposed to air, surface molecular sieve will lose activity.
