Properties
Viton® sponge sheeting is closed cell and manufactured with a skin on both sides to provide increased tear resistance. Like solid Viton it has a high temperature resistance and good resistance to aliphatic and aromatic hydrocarbons, oils, fuels and lubricants. Viton® sponge sheeting also has good resistance to acids, weathering and ozone.
