摘要 |
Manufacture of expandable styrene polymers which on expansion provide oval saddle-shaped discs suitable for use as bulk cushioning material. In the process, cylindrical extrudates of expandable styrene polymers are deformed at form 70 DEG to 90 DEG C by means of rollers to form strands of oval cross-section, which strands are then sliced to form discs by cutting in the direction of the short axis of said oval cross-section. |
