Nitto Semi-Closed EPDM Foam

Unlike standard EPDM sponge, Nitto EPDM super soft (Ethylene Propylene Diene Monomer) is a semi closed cell sponge.

This means that it contains a mixture of both open and closed cells, giving the sponge the flexibility to compress more easily.

Due to the properties of Nitto EPDM super soft sponge and other EPDM materials, it is ideally suited for use in outdoor and automotive applications. Nitto EPDM semi closed cell sponge exhibits impressive ozone, UV, weather, and general resistance as well as withstanding a temperature range of between -40 ˚C and 135˚C.

Nitto EPDM super soft sponge is a model solution to sealing outdoor applications, to protect against dust and moisture.
