The puffing of EPS (expanded polystyrene) resin, creating the puffed polystyrene beads is step one in producing EPS Foam blocks. The EPS resin is puffed when in the manufacturing course of they’re places in a closed chamber and uncovered to steam.
The Pentane gasoline in each bead expands from the warmth causing the beads to grow by 30 to 35 instances their unique size. When they’re totally puffed the beads are primarily made up of air. Because of the warmth the beads remain mushy at this point, to help them harden with out being ruined they’re transported to a chamber designed to assist them dry.Once dry the ultimate product is locations in large bags to allow them to be shipped. If the end consumer is demanding a very massive amount of those EPS foam beads, they can be blown instantly into the back of a trailer and transported to the consumer.
Puffed polystyrene beads are used for several different functions in addition to the manufacture of EPS blocks. Two of the commonest are the production of bean bag chairs and the production of light-weight concrete. The beanbag chairs are crammed with foam filler at the producers once they blow the beans for a bean bag into the empty bean bag shell, once full they seal the chair. The puffed EPS beads are economical filler with distinctive properties that would not be obtained using some other material.
