Abstract: An oxygen-absorbing composition including iron and a soluble tartrate. A method of absorbing oxygen from a closed environment including the steps of providing an oxygen-absorbing composition containing iron and a tartrate, injecting water into the composition, and placing the composition into the closed environment. An oxygen-absorbing packet containing iron and a tartrate. All of the foregoing-mentioned compositions preferably include an electrolyte.

Abstract: The invention relates to improved resin bonded sorbent compositions and articles of manufacture fabricated therewith, such as air conditioning and refrigeration components. The introduction of desiccants into resinous molding compositions enables the elimination of more conventional bagged desiccant containments. The novel molding compositions of the invention and parts fabricated therewith are multi-functional, beneficially combining structural, mechanical and adsorptive capabilities without requiring the usual reinforcing additives. Consequently, with the omission of reinforcing additives the novel molding compositions of the invention are further characterized by higher moisture adsorptive capacities by allowing for higher sorbent loading factors than prior adsorbent-containing molding compositions.

Abstract: A device for controlling relative humidity in an environment with a solidified humectant composition. The solidified humectant composition is made from a humectant salt, water, and a carrier. The solidified humectant may be formed into a tablet with the aid of a binder, or it may be contained within a thermoformed felt material, a sachet, or a water permeable canister. In a preferred embodiment, the sachet is made of a micro-perforated polyester/paper/polyethylene material. Preferred humectant salts include CaCl2, K2CO3, LiCl2, NaCl, K2SO4, and combinations thereof. A preferred embodiment of the present invention includes the use of one or more of: an antimicrobial agent, activated carbon, a volatile organic, a moisture adsorber and an oxygen absorber, in combination with the solidified humectant salt.

Abstract: A method of selecting an appropriate resin bonded sorbent composition which may be used at least for in part making an enclosure to protect contents from external humidity including the steps of: a) selecting a plurality of resins, a plurality of sorbents and a plurality of ratios therebetween to form a plurality of composites; b) calculating a plurality of failure times for the plurality of composites, wherein each failure time of the plurality of failure times is based on when an internal relative humidity of each composite of the plurality of composites is equal to the maximum internal relative humidity; c) determining which of the plurality of failure times is greater; and, d) selecting one composite of the plurality of composites based on the result of step (c).

Abstract: In an elongated strip of desiccant packages each package includes a body formed from spun bonded non-woven polyethylene; a lateral seal at each end of the body, the seal comprising a knurled direct, adhesive free, seal having intersecting sealing lines each of which is arranged at an angle to the longitudinal axis of the package; a longitudinal seal extending between the lateral seals printed indicia on the package disposed substantially between the lateral seals, and spaced from the longitudinal seal, the longitudinal and lateral sealing areas being substantially free of printing; at least one registration mark( on the body, the mark disposed at a known distance from at least one of the lateral seals, and outside of the sealing area; a sorbent material within the body.

Abstract: An oxygen-absorbing composition, device, and method for oxygen scavenging in a low moisture environment are provided. The present invention provides an oxygen absorbing composition which includes an oxygen reducing agent, water, a carrier, an electrolyte salt, and a humectant salt, which may be the same as the electrolyte salt, present in an amount sufficient to reduce the water activity of the composition to below 0.6. Also included are methods of using the composition.

Abstract: A hydrocarbon adsorber and a thermoplastic resin combined and formed to a porous scavenger for insertion into the air intake system of a motor vehicle engine. The resulting porous scavenger adsorbs volatile hydrocarbon molecules from raw fuel remaining in the air intake when the engine is shut off. The adsorbed molecules are then stripped or purged from the scavenger and reintroduced into the air intake when the engine is next started.

Abstract: Heterogeneous oxygen-scavenging particles are formed by dry coating activating component particles onto oxidizable component particles, largely through a succession of mechanical motions. The component particles are repeatedly mixed, compressed, and sheared. Smaller activating component particles coat the surface of larger oxidizing component particles by force-induced contact, while irregularities are removed by abrasion among the particles. The oxygen-scavenging particles can be blended together with a base polymer into a masterbatch having a higher concentration than required for use as an active barrier to oxygen permeation. The masterbatch can be diluted with the same or a compatible polymer to form the active barrier.
