Baniar Expandable Polystyrene (EPS) can be easily pre-expanded down to 11 g/l after one expansion and down to 7 g/l after a second one.
The recommended ageing time before molding obviously depends on the pre-expanded density and ranges from 6 to 24 hours.
Molding is characterized by fast cycle times. In addition, due to an excellent reaction to steam, it is possible to mold with a higher content of recycled material without significant reductions in properties.
