Neoprene Foam

Neoprene foam is the material of choice when oil exposure, UV weathering, and general-purpose environmental sealing must all be addressed by a single closed-cell material. Its polychloroprene chemistry delivers moderate oil and flame resistance alongside good ozone and weathering performance across a serviceable temperature range, making it one of the most broadly deployed gasketing foams in NVH, enclosure sealing, and HVAC applications. H-O Products carries closed-cell neoprene foam in the SCE series across a range of densities and converts them to customer specification.
