Abstract: Improved blowing agents for thermoplastic and thermoset polymers are disclosed which contain silicate based compounds containing from about 5 to about 40% water and which expand or intumesce when heated to at least about 5 times their initial volume, which blowing agents are highly effective, predictable, stable and microwave receptive, do not cause post-blow, and which also act as an initiator or accelerator for other organic blowing agents.

Abstract: A method of producing dense, free-flowing alkali metal silicate-based particles which, when sufficiently heated, will form lightweight particles of a spumiform nature which may be employed as thermal or acoustical insulation or as a lightweight filler for gypsum or cement or for numerous other purposes. The method comprises premixing a liquid alkali metal silicate with selected fillers and/or insolubilizers, adjusting the temperature and solids content of the mixture until it passes into a dilatant gel state which will fracture when extended at a rate of between about 3 and 95 cm/minute, and subsequently extruding or pelletizing the gel at this temperature to form particles which are conditioned in an air stream for at least one second and then dried to a moisture level of between about 5 and 30%. These particles or pellets serve as a stable intermediate which can be expanded to form lightweight spumiform particles by further heating at a later time or at a remote location.

Abstract: Processing aids comprising amorphous particulate silicates containing from about 2% to about 50% water, are utilized in processes for compounding thermoplastic resins, allowing higher levels of additives to be more effectively incorporated into the thermoplastic resins. The processing aids allow greater dispersion of pigments and other additives in compounded thermoplastic resins and concentrates.

Abstract: A method is provided for producing dense, free-flowing and non-caking alkali metal silicate-based particles which are heat expandable into lightweight particles of a spumiform character. Pursuant to the invention, one provides at a selected temperature a dilatant aqueous gel comprising an alkali metal silicate as the majority non-aqueous component, the silicate being present in the gel in a dissolved state; and the non-aqueous content of the gel being in the range of from about 38 to 65% (w/w). Shearing forces are imposed upon the gel which exceed the flow response characteristics of the gel, whereby the viscosity of the gel becomes sufficiently high to cause a discontinuity in the gel, resulting in disruption into discrete particles. The discrete particles are conditioned while being maintained as separate entities to thereby form a skin on the particles so that they will not agglomerate or coalesce with one another. The conditioned particles are dried to form particles having about a 5 to 40% (w/w) moisture level.

Abstract: Apparatus for continuous production of intumesced, expanded, puffed, or exfoliated particles. A rotatable processing table is driven by a speed controllable motor connected to rotate the table at a desired rotational rate. Particulate feeding means overlie the table for depositing the particles to be intumesced onto a first sector in the path of the upper surface of the processing table during rotation thereof. Heating means are mounted above and below the plane of the processing table at a second sector in the rotational path of same which is spaced from the first sector, and heat expand the particles during passage through the second sector. A scraper blade is mounted above the processing table at a third sector in the rotational path of the table which is spaced and downstream from the second sector. The bottom of the blade is in sliding contact with the rotating table, the blade being adapted to intercept the expanded particles advancing on the table surface from the second zone and move the particles toward the periphery of the table. A collector is positioned to one side of the processing table and beneath the end of the scraper blade remote from the table axis of rotation, for receiving the expanded particles as same are swept by the blade from the table.
