Molecular Sieve is the most aggressive of the primary desiccants and our first choice for the most demanding and unique applications. A distinctive feature of this non-hazardous synthetic product is our ability to control the uniformity of pore size openings during the manufacturing process.
This yields selective adsorption characteristics that can be very useful drying packages without removing other desirable molecules, such as volatile organics that might be present in the package. Molecular sieve can hold moisture to temperatures well past 450°F (230°C) and, because of its high affinity for moisture, can bring the relative humidity in packages down as low as 10%.
