The following are brief summaries of the compounds used at Clean Seal, Inc. These summaries are by no means all-inclusive. However, a majority of sealing, gasketing, and weather stripping needs can be met using these materials.



Ethylene-Propylene-Diene-Monomer is well known for its excellent ozone, weathering, and aging resistance. It also has excellent water and steam resistance, maintains its flexibility at low temperatures, features excellent resistance to alkalis, acids, and oxygenated solvents, and is very color stable. It is not recommended for resistance to oil, gasoline, and hydrocarbon solvents. EPDM is found in a wide range of applications and is excellent for use outdoors.


EPDM's service temperature ranges from -20°F to 300°F.




Neoprene has moderate resistance to oils and gasoline. It features good flame resistance, weathers well, and has very good resistance to abrasion, flex cracking, alkalis, and acids. However, expect poor resistance to aromatic and oxygenated solvents and limited flexibility at low temperatures. Neoprene is generally considered an excellent all-purpose material with a solid balance of properties and few limitations.


Neoprene's service temperature ranges from -10°F to 225°F.





Nitrile has very good oil and gasoline resistance, permeability, and heat and abrasion resistance. Its resistance to alkalis and acids all increase as the nitrile content of the compound increases. Nitrile must be specially compounded for resistance to ozone, sunlight and natural aging, and has poor resistance to oxygenated solvents. Nitrile is superior to neoprene in oils and solvent resistance, but is not recommended for applications where it is exposed to severe weathering.


Nitrile's service temperature ranges from -30°F to 275°F.




Solid rubber product with no voids or cells. Available in a range of various durometer hardness.




Silicone features excellent resistance to ozone, sunlight and oxidation, and is very color stable. It also maintains excellent flexibility at low temperatures, has outstanding resistance to high heat, low compression set, and is a very good electrical insulator. However, it is not recommended for applications which require abrasion resistance, tear and cut growth resistance, and high tensile strength. Nor is it recommended for resistance to oil, gasoline, solvents, alkalis, and acids.


Silicone's service temperature ranges from -65°F to 400°F.



Non-Stock Items, Minimum Requirements

Due to minimal customer usage and sales history, some profiles are no longer stock items and must be purchased at a minimum order quantity.
