EPS HS321

Description

High Density Block, Shape Molding HS321 is used as a multi-application packaging material for contour moldings with a minimum wall thickness of 10 mm. Properly processed EPS foam packaging made from HS321 provides high mechanical strength also with low densities. It is not hygroscopic and does not become friable in low temperatures. Molded EPS packaging parts have to act as shock absorbers and cushion their content against blows from outside, i.e. they have to absorb the energy released in an impact. The mainly closed cell structure of molded foam parts made from HS321 absorbs the impact stress as”deformation work”. In this process the air enclosed in the cells is first compressed, while bigger impact forces may also deform or crack the cell walls
