Open cell foam is a rubber like product made by incorporating an inflating agent such as sodium bicarbonate into the rubber compound.
Open cell neoprene sponge rubber.
With a great compression rate it can also handle physical abrasions and oil very well.

Foam is usually classified as open cell when more than half of its cells are open.
A key feature of our open cell epdm sponge is the materials unique cell structure.
Due to this important structural difference closed cell foam rubber normally has higher compressive strengths and lower absorption rates.
This agent gives off a gas which expands the rubber during vulcanization.
Open cell foam foam is commonly divided into two types of rubber based on cellular structure.
This open cell rubber contains a blend of sbr and neoprene rubber.
Closed cell foam is created by forcing gas into the foam while in a liquid state.
Despite being referred to as an open cell material this product actually utilises a semi closed cell structure.
This enables it to combine the physical characteristics of a fully open cell material with the sealing capabilities of a closed cell material.
