JSP has developed a unique form of EPP, which features air pockets, or voids, within the bead structure. Shaped in cylinder form, as opposed to spherical form, Porous EPP (P-EPP) provides distinct advantages in certain applications, including acoustical panels for use in challenging environments.

The cylinder shape of Porous EPP beads lessens the component weight, increases acoustical performance in certain frequency ranges, and results in a very lightweight product with resilience and good structural integrity.

 What might an application be for this material?














With this concept (below) the dishwasher would be much quieter and mgf it would be greatly streamlined!

View or download pdf of this concept (more info than shown here) quiet dishwasher . It's a 4mg file, but worth the wait.
