PVC foam blown with a physical blowing agent comprising a gaseous HFC is provided.

Polystyrene-based foam material for the production of for example label material, wherein the foaming has been made with a blowing agent and preferably a nucleating agent, wherein the blowing agent is for example a decomposable blowing agent (chemical blowing agent) or consists of for example carbon dioxide, nitrogen gas or even water, and with a thermoplastic elastomeric blend composition consisting of at least one styrenic block copolymer and one homogeneously branched ethylene-interpolymer.

A foam board, for fabrication of sandwich panels made of a face sheets bonded over each side of the foam board, has two opposed planar faces having an embossed pattern in the faces. The embossed pattern has three series of parallel linear indentations, each of the series intersecting the other two series at an angle of 60.degree., such as a series of interlinked equilateral triangles angularly offset from the other two series. The indentations into the surface of the foam boards are sufficiently...

Dispenser apparatus for multicomponent products comprises a pair of dispensing valves and a manually graspable support bracket. A valve-supporting assembly, mounted on the bracket and substantially defining the posterior portion of the apparatus, attaches the valves to the bracket and includes a pair of rearwardly extending tubular inlet members for connection to a remotely located product supply container. The apparatus further includes a dispensing nozzle unit spaced apart from the dispensing ...

A foam laminate, the lower facing sheet is a preformed metal pan with sharp vertical edges, two opposite edges of the pan being shaped, near the foot thereof, one as an outwardly-extending and the other as a co-operating inwardly-extending hairpin bend such that, when a pair of pans are to be connected, the hairpin bends form a snap-fit with each other.

A brush for dusting and for removing snow from automotive windshields and the like made up of a rigid handle having a slot cut in one end and a rectangular block of relatively flexible closed cell foam disposed in the slot with rivets holding the foam in clamped relationship in the slot. The foam material extends from one side of the handle several inches so that it can be used to get into recesses in windshields and similar places.

To provide a type of phenol foam characterized by the fact that the phenol foam is formed by using a hydrocarbon as the foaming agent. The phenol foam has excellent heat-insulating performance, high compressive strength and other mechanical strengths, improved brittleness and is friendly to the environment of the earth.

The invention disclosed relates to a foam-forming composition, for suppression/containment of blast from explosive devices. The composition comprises, a) a surfactant 40-80% w/w b) a foam stabilizer 0-7% w/w c) a polyalkylene glycol 10-30% w/w d) water, balance to 100%.

Use of a foam control laser having a wavelength corresponding to a mode specific peak of the absorption spectrum of a liquid constituent of the form greatly increases the efficiency of foam control.

A foam composite made up of a scaffold of a substantially hydrophobic foam 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.
