New Economical Filler for Elastomer Composites

Abstract

Incorporation of fillers in elastomers results in a profound effect on mechanical properties of the composites formed. Significant study has been carried out on this topic. Fillers are customarily classified into organic and inorganic. The latter class includes calcium carbonate, talc, barium sulphate, china clay (kaolin), magnesium oxide, alumina, silica, etc. Flyash, a waste product of thermal power stations contains inorganic oxides, hence, it was thought that it could be used as filler for elastomers. Flyash is generated in huge quantities ORDER REPRINTS a filler in elastomer (polybutadiene rubber). The composites were prepared with various percentages of flyash and were subjected to testing for mechanical properties. The results were compared with the composites containing conventional fillers, i.e., calcium carbonate and talc. The results indicated that flyash could be used as a filler or as a supporting filler. The relevance of this study could help in solving the problem of disposal of flyash and, at the same time, the polymer industry will benefit by identifying an economical filler.

Mechanical Properties of Fly Ash Filled High Density Polyethylene

“…9,No.3 also shown the advantageous use of treated fly ash in a wide variety of polymer matrices. [4][5][6][7][8] Although incidental success stories are published, a systematic approach on investigating the influence of fly ash on polymer properties for the various different polymer types and the enormous amount of possible formulations has not yet been properly undertaken. As a part of an attempt into this direction, the present work deals with HDPE-fly ash composites.…”

Colored rubber vulcanizates with some magnetic properties

“…The "d" values and relative intensities I/I o of X-ray pattern for samples of prepared pigments were illustrated in Figure 1, and the data showed that for the three mixtures including 3Al 2 …”

“…2 It was found that the Einstein-Guth-Gold equation could be applied to the filled vulcanizates over a wide range of strains if the effective volume of the filler was introduced.…”

“…On the other hand, incorporation of filler in elastomers results in a profound effect on mechanical and physical properties of the formed composites. 1,2 Magnetic powders are inorganic materials that can be embedded in a polymeric matrix imparting special qualities to polymer composites. These fillers enhance properties such as thermal conductivity, electrical conductivity, response to magnetic fields, heat capacity, etc.…”

“…These fillers enhance properties such as thermal conductivity, electrical conductivity, response to magnetic fields, heat capacity, etc. 2 The mechanical properties of the composite are usually dependent on the polymeric phase and the magnetic effect of the inorganic filler. These magnetic powders may include ferrites and intermetallic composites of rare earths.…”
