Coarse expanded products

FIG. 12-95a Air-lift pneumatic-conveyor dryer includes partial recycle of dry product and expanding tube and cone sections to provide longer holdup for coarse particles. (Bepex Coip. )... 

Artificial coarse aggregates These are mainly slag and expanded shale, and are frequently used to produce lightweight concrete. They are the by-product of other manufacturing processes, such as blast-furnace slag or expanded shale, or pumice for lightweight concrete. 

These multiblock terpolymers are laboratory products. They were prepared in order to evaluate the influence of the incorporation of a third block into the macromolecule on the copolymer phase structure. An attempt was made to change the morphology (from microphase to nanophase) in the Hytrel -type elastomers thereby, the interphase could be expanded. The elastomers having a nanophase structure are polymers with a better shape memory than those with coarse morphology. By the incorporation of a third block, the properties of multiblock polymers can be modified so that different shape memory effects can be achieved (for shape memory effects, see also Chapter 18).
