Unlike chemical dryingagents, these adsorbents function by a physical process only, sono reaction by-products are formed that can adversely affectproduct properties. MOLSIV powders can be added to plasticformulations to physically adsorb odor-source molecules thatare generated from polymer oxidation, migration of externalcontaminants, or dissolution of , Adhesive, Sealant and ElastomericTreating (CASE):Molecular sieve powders removemoisture from epoxies, coatings, adhesives, sealants,elastomers, metal rich paints to eliminate curingproblems such as CO2off-gassing, blistering and degradation ofother physical properties.

3 Vinyl Based Foam Dehydration:Molecular sieve powdersdehydrate to eliminate pinholes and blemishes on vinyl surfacesduring high-temperature curing. Polymers:Molecular sieve powders have beenproven effective for their ability to reduce taste andodor problems in injection and extrusion blow-molded containers, tie-layer and sealant polymers,extrusion coatings and multi-layered packaging. Industrial Gas Purification + Air SeparationHigh purity industrial gases such as O2, N2, H2andCO are produced in a variety of ways. UOP s MOLSIV adsorbents play an essential role in these processesbecause of their high adsorption selectivity andcapacity. In addition, UOP s aluminas are often used for CO Production:Molecular sieves remove water and CO2toprevent freezing in downstream cryogenic separation :Molecular sieves remove water and CO2from compressed air to prevent freezing in downstream cryo-genic separation processes.

4 H2 Production:Molecular sieves remove impurities such ashydrocarbons, CO and N2from gas phase :Spherical activated aluminas are used for dehy-dration systems as in pressure swing adsorption + StorageMolecular sieves physically adsorbwater molecules, reducingwater concentration levels to less than 1 ppm in many applica-tions. MOLSIV adsorbents are incorporated directly into plasticspackaging and used in desiccant dehumidifiers (dry boxes) toprotect moisture-sensitive contents. Packaging:Molecular sieves are added to protectproducts such as pharmaceuticals, batteries, film,fuel propellants, machine parts and electronic com-ponents. The selective adsorption characteristics ofmolecular sieves can be useful when it is necessary to dry a pack-age without removing other desirable compounds from a :Molecular sieve are used in cabinets and enclosures asdesiccants to trap airborne moisture.

5 Common applicationsinclude the prevention and protection against oxidation (rust),growth of fungus on optics, the preservation of lab materials andprotection of moisture sensitive devices. Air DryingCompressed air is dried for use with plastics processing, air brakes,sterile environments, sensitive instruments, packaging and othercritical process operations. UOP s MOLSIV adsorbents play anessential role in these processes because of their high dew pointdepression and dynamic drying capacity. High strength and attri-tion resistant characteristics guarantee thousands of cycles underextreme conditions over a long lifetime. Plastic Resin Drying:Molecular sieves are used indesiccant dryers to dry hygroscopic plastic resins forapplications such as PET pre-form molding, high-volume extrusion of sheet and film, or large partinjection molding.

6 Because of their high affinity for moisture atvery low dewpoints, molecular sieve desiccant dried air can pro-duce dewpoints of -40 F and Air Drying:Molecular sieves are used in desiccantdryers to produce instrument grade air from compressor air. Brake Air:Molecular sieves are used in heavy andmedium-duty truck, bus, and train air brakes as self-renewing dehydrators. Dehydrating the compressedair keeps the brake lines from freezing and Air Applications:Molecular sieves are used to dryair for use in pharmaceutical, electronic and food SIEVECHARACTERISTICSTypeNominalFormBulk DensityHeat ofMoleculesMoleculesPore Diameterlb/cu-ftAdsorption (max)Adsorbed*ExcludedAngstromsbtu/lb H2O 3A3 Powder3518001/16" Pellets401/8" Pellets404A4 Powder3218001/16" Pellets441/8" Pellets448 x 12 Beads444 x 8 Beads4414 x 30 Mesh445A5 Powder3218001/16" Pellets441/8" Pellets4413X8 Powder2718001/16" Pellets401/8" Pellets408 x 12 Beads404 x 8 Beads40*Each type adsorbs listed molecules plus those of preceding with aneffective diameter <3angstroms includingH2O and NH3 Molecules with aneffective diameter <4angstroms includingH2O, CO2, SO2, C2H4,C2H6, and C3H6 Molecules with aneffective diameter <5angstroms includingn-C4H9OH, n-C4H10,C3H8 to C22H46, R-12 Molecules with aneffective diameter <8angstroms includingC6H6, C7H8 ASGEA dvanced Specialty Gas EquipmentASGEM olecules with aneffective diameter >3angstroms (ethane)
