Ko te raina tapahi EPS e mohiotia ana ko te raina tapahi EPS tonu aunoa ranei te raina tapahi polystyrene kua whakawhānuihia aunoa, he miihini tapahi EPS aunoa me te punaha tautuhi waea tapahi aunoa.

Ko te kaha o te tapahi i runga i te kaha o te tapahi i tonohia mai i te kaihoko.
Mena he nui ake i te 500M3 te kaha tapahi ka tonohia mo ia ra, neke atu ranei, katahi ka tino whakapai ake te raina tapahi EPS tonu i to mahi tapahi.

E rua nga take:

1)EPS tapahi raina mahi tonu

2) Ko te tere tapahi o te raina tapahi EPS mo te 1.5m / min i runga i te 15kg / m3 EPS poraka kiato

3) Katoa aunoa rite kōwhiringa
