A moisture absorbing product, particularly for use in containers or railcars, includes a desiccant container including a plurality of separate desiccant holding compartments, each containing a quantity of desiccant material, a support over which the desiccant material is placed, a sheeting material, which substantially covers the desiccant container and which is permeable to gaseous water vapor but substantially impermeable to liquid water, and a strap with hook, secured to or within the support or desiccant container, which strap and hook are useful for hanging the moisture absorbing product within the container or railcar.

Moisture absorbing product for use in containers

There is disclosed a plate-shaped pressed body (wafer) produced from an inorganic sorbent and a binder, having a thickness of less than 700 &#x3bc;m, which is produced by the process of compressing a mixture of the inorganic sorbent, the binder, and optionally water and compression aids at a pressure of at least 70 MPa, wherein the weight ratio of dry sorbent to dry binder is between about 4 and 0.7 and the water content of the mixture, measured at 160&#xb0; C., is between 8 and 20%; and calcining the resulting pressed body at temperatures of at least about 500&#xb0; C., until the water content is substantially removed.

Plate-shaped pressed bodies

An apparatus for packaging electronic components, particularly integrated circuits, which includes a carrier tape into or on which the integrated circuits can be secured, a packing reel, to which is secured the carrier tape, wherein one or more components of the packing reel is composed of a plastic material and a desiccating material, and preferably a copolymer, and optionally an electrostatic dissipating product. The packing reel may further include a humidity indicating system. The apparatus may also be placed within a water and moisture-proof barrier bag for shipment purposes.

Apparatus for packaging electronic components including a reel entrained with desiccating material

A moisture-absorbing polymeric material is disclosed which consists of a combination of a thermoplastic material with an absorbing agent. The thermoplastic material is chosen such that when the absorbing agent is added to the thermoplastic material in the molten state and subsequently formed into a product, the absorbing agent tends to migrate towards the surface of the moisture-absorbing polymeric material to form a migration zone, wherein the absorbing agent is more highly concentrated in the surface of the polymer material than towards the interior.

Absorbent polymeric material

A process for the microbial activation of layer silicates.

A rubber compound is described containing as a reinforcing filler a layered silicate which is obtained by excessive leaching of a smectitic layered silicate with mineral acids. The rubber compound further contains at least one diene polymer or copolymer and a coupler containing groups reactive with the filler. There is also described a method for production of the rubber compound and molded articles produced from the rubber compound.

Rubber mixture that can be cross-linked by sulfur, method for the production thereof, and cross-linked rubber mixtures and shaped bodies that can be obtained therefrom
