In order to produce a solid foam structure the use of a composition with a binding agent is recommended. Said composition contains an elastically compressible filler material instead of a propellant gas. The result is an environmentally friendly and easy means of coating, gluing, sealing or filling using foamed structures. Said composition is particularly useful when used as in-situ foam for assem...

The present invention relates to a plate containing as a main component a cristallizable thermoplastic material, at least one nucleating agent and at least one UV stabilizer, and to a cristallized mould to be made from such a plate, its making and use.

A sintered powder metal part is surface densified by surface heating followed by repressing. Surface heating is preferably done to a temperature which is just below the critical temperature where the steel alloy material of the part transforms from a ferritic to an austenitic microstructure. Repressing is in a die set which is smaller than the part by 10 % of the surface heated depth. The hot skin...

An aqueous dispersion has particles dispersed in a continuous dispersion medium. The particles, preferably no more than about 2 micrometers in size, are formed of a mixture of styrene-ethylene/butylene-styrene (S-EB-S) block copolymer having end blocks each with a weight average molecular weight of more than about 15,000 Daltons and an oil such as a mineral oil. The dispersion medium is a mixture ...
