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.
