Blends are also selected in an effort to improve raw material economics, without compromising finished part quality. Elastomer blends are almost always heterophase systems, i.e., dispersions of one type of elastomer in a continuum or matrix of the other. This heterogeneity is because most elastomer pairs are not mutually soluble.
