PORON® Soft Seal 4701-15 Series
Low-density polyurethane foam for dust sealing, shock absorption, and thin gasket applications
PORON® Soft Seal 4701-15 Series is a low-density microcellular polyurethane foam designed for flexible dust sealing and shock-absorbing applications. It is a strong option for thin designs that need excellent compressibility, conformability, and long-term sealing performance.
With enhanced surface toughness and reliable durability, PORON® Soft Seal 4701-15 performs well in custom die-cut gaskets and seals for electronics and other space-constrained applications. Its low density helps support delicate assemblies where very low closure force matters.
