As iaolierfeSrper known moldings atts porous ferennlsaren iCunststoffköritem, ü ± q uater ¥ arsteeiawirkucg be plastically and, xbx Yalamen vergrSasern * Bieser Torgaog than aogeiiaöQte?

In order to enclose this factual part 2u, according to the definition, it is primarily a rorge silage that the iCiiQst atomic grains of a silver suction made of chlorinated »thermoplastic & eQ substances Britzimg flsffiiaeaisemaesde sase are separated out so there is no risk of exposure to the surface of the sico.flammable plastic mass.

It is known that the plastic grains become plastic under the action of heat, as a result of which they stick to one another on the one hand and, on the other hand, if necessary, change their volume under the action of a propellant which is located inside the grains. enlarge this. As a result, the grains introduced into a fora are pressed against one another and can thus form a uniform body. The fact that the coating consists of iron thermoplastic material, among other things, has the major advantage that these thermoplastic coatings follow their changes in shape when the grains of non-material are heated, with a closed absorbent layer still remaining. When the compressed grains cool down, they remain connected to one another, namely the thermoplastic eye of the individual Homer increases the strength of the molded body. These thermoplastic coverings of the outer grains appreciate the finished fora body to a greater extent against moisture absorption or other harmful airways .

In a preferred embodiment of the invention the jbersug of the grains consists of one Dispersion. On the one hand, piping shows chlorinated, organic »

thermoplastic polymer! sationsprodulcte, such as 2 * 3 · chlorinated paraffin, chlorinated rubber, in particular polyvinyl chlorides and on the other hand has metal oxides, such as 2 · 3 · IiO ₂ ^, especially Sb ₂ 0 ^ ·

Another Yörschlsg of the fire goes here, a 50 ^ igen dispersion of polyvinyl chloride and Sb ^ O- a stabilizer and / or a ^ Add srulsifier.

It should be mentioned that the Kuaststofxkörnsr with the "descriptive coatings before their sundversshaumung provided feans. This driving is easy and has compared to the previously used.-'- ■ '. Driving no additional effort.

You drawing appears to be a guide example of the game Invention.

Jer molded body 1 according to FIG. 1, which may be used as an insulating body, consists of individual elements Sold folystyrene grains 2 with coatings 3 (see Fig. 2). '

For example, 25 g of foamed polystyrene coating is obtained which consists of an ice 50% bispersion of 5 g polyvinyl chloride and 5 g ^sfe 2 ° 3 / or one of the usual emulsifiers «

The cover 3 can be skin-like, even film-like be designed. The fire-retardant © effect as well as an increase in strength is achieved trotadesi. They make skin-like or film-like coatings possible Use of a relatively small amount of sweet, so that the desired small rough surface

of the finished molding increased only insignificantly is, «emäsa the design example künen Forfsköirga · with a rough weight of 25kg / m "'.

Not only insulating bodies, but also molded bodies of any type and for any purposes can be considered for the invention. So can z.3. Toys, utensils, like! Pith helmets and the like. Can be made from this.
