The following materials are available for ordering. It is the end customer’s responsibility for qualifying the MWS units in the intended end application.
HNBR: Hydrogenated nitrile was developed as an air-resistant variant of nitrile rubber. With the HNBR material, the carbon-carbon double bonds in the main polymer chain are saturated with hydrogen atoms in a process called “hydrogenation” that improves the material’s thermal stability and oxidation resistance.

- Temperature: -25 to 300 deg F
- Color: Black
- Durometer: 60A
FKM/VITON: Fluorocarbon (FKM) has excellent resistance to high temperature and a broad range of chemicals. Permeability and compression set are excellent.

- Temperature: -15 to 400 deg F
- Color: Brown
- Durometer: 70A
Fluorosilicone (FVMQ): Fluorosilicone is a silicone polymer chains with fluorinated side-chains for improved oil and fuel resistance. The mechanical and physical properties are very similar to those of silicone.

- Temperature: -90 to 350 deg F
- Color: Blue
- Durometer: 60A
Ethylene Propylene Diene Monomer (EPDM): EPDM is an M-Class rubber under ASTM standard D-1418; the M class comprises elastomers having a saturated chain of the polyethylene type (the M deriving from the more correct term polymethylene). EPDM is made from ethylene, propylene, and a diene comonomer that enables crosslinking via sulphur vulcanisation.
- Temperature: -75 to 250 deg F
- Color: Black
- Durometer: 35A
