The present invention concerns a foam having a bulk density of less than 250 g/l; the foam having a stability in air of at least 15 seconds (and preferably at least 30 seconds), the stability being defined as the time for the foam to collapse to half its volume when measured in a 111 mm internal diameter and 62 mm internal height glass beaker; wherein the foam has a stability on water at 20.degree. C. of less than 2 hours, the stability on water being defined as the time taken for a 150 ml foam ...

A foam of very small, microscopic bubbles of surfactant, each bubble containing a small quantity of water, is mixed with a water/cement mixture having a water to cement ratio of less than 0.33. The small bubbles have a ball bearing effect on the smaller cement and sand particles, increasing plasticity or flowability and thus reducing the water requirements of the mixture. The foamed cement mixture is laid to form a desired concrete structure, and the bubbles disintegrate or transform to leave vo...

An article comprising two or more layers. One or more of the layers includes of a polymeric foam tape containing one or more curable resins. One aspect of the present invention is to use the article as an orthopedic casting splint.

The present invention provides various pharmaceutically active topical delivery compositions. In particular, compositions of the present invention are present in a pressurized contained comprising a quick-breaking alcoholic foaming agent, such that when the composition is released, i.e., dispensed, from the pressurized container, a quick-breaking temperature sensitive foam is formed. In addition, the present invention provides various aspects related to such compositions, including methods for m...

The disclosure describes is a portable activity surface with foam construction with various utilitarian features and configurations.

An article including a polymeric foam having a thickness of less than about 3/16 inch (about 5 mm) and one or more curable resins.

A foam composite made up of a scaffold of an open cell hydrophobic material having plurality of surfaces defining a plurality of pores, and a coating of a substantially hydrophilic foam material disposed upon the surfaces of the hydrophobic foam. The resulting foam composite exhibits structural characteristics of the hydrophobic foam and absorbency characteristics of the hydrophilic foam.

The outside of an elongated exercise roller formed of a compressible, foam material, is modified. Instead of being cylindrical, a portion of the outside has a gentler curvature over part. That change makes balancing easier.

A foam producing nozzle for attachment to a spray nozzle which is readily attached and removed therefrom. The foam producing nozzle has air channels which do not lend themselves toward leaking. The dilution rate of the chemical concentrate is not affected by the foam producing nozzle.
