AMINIPLASTICS (izomit, melmeks, plaskon, pollopas, skanopat, an ultrapass, etc.), plastic on the basis of aminoaldegidny pitches, hl. obr. mochevino-or (and) melaminoformaldegidny. Are a part of aminiplastics: fillers - cellulose, talc, asbestos, wood flour, glass fiber or other - the modifying additives - di - or trietanolamine, thiourea, polyamides, kremniyorg. oligomer or polyvinyl alcohol - lubricant in-va (up to 0,5% of weight aminiplastics) - stearin, stearates Zn, Mo, A1, glitserilstearaty-organic and (or) the miner. pigments. Let out aminiplastics in the form of press materials (powders, granules, fibrous products), layered plastics, polyfoams (see Karbamido-formaldegidnye polyfoams).

Tekhnol. process of receiving aminiplastics includes synthesis binding (see Melamino-formaljdegidny pitches, Mochevino-formaljdegidny pitches), impregnation of a filler by it, drying of composition, its crushing and, if necessary, tabletting or a granulation. Impregnation of m. it is carried out in two ways - 'wet' (is more widespread) also 'dry'. In the first case the filler is mixed with liquid pitch, in the second, etc. components combine solid pitch, a filler in the warmed shnekovy cars or on rollers. The painting m components. are entered at wet impregnation of a filler or in a powdery aminiplastics - in the latter case use mixers of drum type.

Aminiplastics process into products pressing (135-170 °C, 25-50 MPas), molding under pressure (plastication t-ra up to 90-115 °C, t-ra of a form of 140-170 °C, pressure of 100-200 MPas), molding pressing. Formation is followed by hardening of pitch with formation of mesh polymer.
