PORON® ShockSeal™ 4790-79


PORON® ShockSeal™ 4790-79 Foams For Custom Gaskets In Handheld Devices

PORON® ShockSeal™ foams are a trusted solution in sensitive handheld devices, and are now available to the general industrial markets as well. This thick grade material is ideal for applications which require gaskets, cushions, spacers or springs. ShockSeal™ materials perform best in environments where impact protection, long-term reliability, and high compression set resistance is a must.

PORON® ShockSeal™

Handheld Grade PORON® ShockSeal™ Foam

  • As the demand for thinner, larger and more expensive LCD displays continues to grow, designers and manufacturers face new challenges with these increasingly complex technologies.
  • PORON® ShockSeal™ foams are specifically engineered to meet the challenging cushioning, sealing and protection requirements that larger displays demand.
  • Handheld Grade ShockSeal™ foam is available as thin as 0.5 mm, and conveniently conforms to some of the smallest and most intricate manufacturing designs.
  • Handheld Grade PORON® ShockSeal™ foam reduces impact force by up to four times that of competitive material and is almost twice as effective as PORON® 92-12039 foam. In addition, the PORON® ShockSeal™ materials absorb as much or more energy when compared to higher density materials.
  • When high compressibility, excellent impact protection and extreme performance is in demand, designers and engineers turn to ShockSeal™ materials for all of their handheld electronics needs.

Industrial Grade PORON® ShockSeal™ Foam

  • Industrial grade PORON® ShockSeal™ foam (1.57 mm – 12.7 mm thick) is still the undisputed champ of impact force mitigation!
  • When comparing a handful of competitive foams to a 30 cm drop, Industrial Grade ShockSeal™ materials reduce the impact better than any of the rest.
  • Additionally, industrial grades of ShockSeal™ materials are recognized by UL Gasketing and Sealing (UL50E/UL508) and Federal Motor Vehicle Safety Standards 302 (FMVSS 302) specifications. For additional information, please see the ShockSeal™ material data sheets.
