『 HUA JENG EPS 』 EXPANDABLE POLYSTYRENE
HUA JENG EPS ” EXPANDABLE POLYSTYRENE is polymerized through suspension reaction and packed into small round beads which they can be pre-expanded into expansion granules through steam heating. When the expanded granules are stabilized in the air, they shall be guided into the mold for thermoforming by steam heating process.
