US6399665B1 - Dry expansion of expandable polymer beads

Pre-expansion of expandable polystyrene (EPS) and other expandable polymer beads has long been carried out with heat of condensation from steam, which permeates the beads and deposits water droplets within expanding cells of each bead. Because long conditioning periods (to dry the pre-expanded beads) allow much of the blowing agent (e.g. pentane) to escape, the resultant pre-expanded beads

EPS GEOFOAM BLOCKS, MATERIAL PROPERTIES AND …

In the first processing stage the beads of EPS are expanded at a temperature of about 100 - 110 °C in a machine called a pre-expander (Fig.2), into which steam is fed. The high temperature softens the beads and the blowing agent they contain causes them to expand up to 50 times their original size. The final bulk density of the beads depends on

Polystyrene - an overview | ScienceDirect Topics

Solid polymer beads are introduced into a steam chamber and small cells of pentane gas are produced within each bead, producing expanded polystyrene (EPS) beads with a nominal density of 0.02–0.03 gcm −3 (1.3–1.8 lbft −3). The beads are then stabilized at a controlled temperature and humidity.
