Fillers for plastics

With emerging nanoscale fillers where the particle sizes are in the l(X)s of nanometers, the specific snrface area of filler particles can be orders of magnitude larger than that for conventional fillers. As fractional volume of matrix-filler interphase determines the level of reinforcement achieved in the composite, nanofillers can achieve superior properties at relatively low volume fractions, provided they are adequately dispersed in the base polymer.

In the 1990s, carbon microbeads have been produced by a proprietary process using phenoHc resin. Potential appHcations are lubricants, adhesives, and conductive fillers for plastics, mbbers, and coatings (97). 

Because of its extreme insolubiUty, barium sulfate is not toxic the usual antidote for poisonous barium compounds is to convert them to barium sulfate by administering sodium or magnesium sulfate. In medicine, barium sulfate is widely used as an x-ray contrast medium (see Imaging TECHNOLOGY X-RAY technology). It is also used in photographic papers, filler for plastics, and in concrete as a radiation shield. Commercially, barium sulfate is sold both as natural barite ore and as a precipitated product. Blanc fixe is also used in making white sidewall mbber tires or in other mbber appHcations. 

Wollastonite with an aspect ratio of 15 1 is useful as a replacement for asbestos and as a high-strength filler for plastics. The feed material with dgo of 45 [Lm was similarly ground. Beads of 0.3 mm gave faster grinding than 0.8 mm beads, and these corresponded to a bead-particle-size ratio of 19, confirming other results.

Is the trade name for pyrophyllite, a hydrous aluminum silicate. This mineral is chemically a clay but has the appearance and some of the physical properties of talc. The principal use is as a diluent or carrier for agricultural toxicants, PYRAX is also used in water paints, dry wall plasters and as a filler for plastics. 

Silica-based nano- and microsized tubular stmctures have been Icnown since the mid-1990s [1]. The preparation using the sol-gel process is a low-temperature process at room tenqterature and offers scope for manipulation of, e.g., the size and shape of these tubes. Silica-based tubular structures have many advantages, such as easy accessibility, stability, and the possibility of surface functionalization. They can be used for catalysis, separation, reinforcing materials, and fillers for plastics and ceramics.

Silica coatings are applied to particulate materials to modify surface characteristics that interfere with the exploitation of desired bulk properties, as with titania pigments that may photocatalyze the degradation of their vehicle, surfaces of selective zeolite catalysts that may promote undesired reactions, and fillers for plastics that may not disperse in their matrix. 

Among earlier studies of fly ash as a filler for plastics, two U.S. Patents can be mentioned [21,22]. In the first one, fly ash was mentioned in the claims as a filler for a thermosetting composition, in the second one, for a thermoplastic resin. No details were given, though, in examples of the patents.
