Interconnected cell porous body and manufacturing method thereof

摘要

Disclosed is a water absorbent material and an interconnected cell porous body which can be optimally used as a flower arranging pedestal and a plant culture medium. The interconnected cell porous body is formed from a resin composition with a polylactic acid-based resin as the main component. The pore walls, formed by joining together the crushed powder fragments formed by crushing the foam of the aforementioned resin composition, form the interconnected cell structure of the aforementioned porous body. The apparent density greater of the interconnected cell porous body is than or equal to 0.01 g/cm3 and a less than or equal to 0.2 g/cm3; the 10% compression stress is greater than or equal to 0.02 MPa and less than or equal to 0.3 MPa; and the compression recovery rate is less than or equal to 95%. The water absorbent material comprises the interconnected cell porous body.
