EPDM (EPDM, EPM, EPT) Ethylene-propelene, ethylene-propylene-diene
Advantages:
Excellent resistance to heat, ozone, and sunlight; very good
flexibility at low temperatures; good resistance to alkalis, acids, and
oxygenated solvents; superior resistance to water and steam; excellent
color stability.
Limitations: Poor resistance to oil, gasoline, and hydrocarbon solvents, adhesion to fabrics and metals is poor.
Comment:
Because of its unique combination of physical properties, EPDM can be
used in an unusually broad range of products. Aside from applications
requiring resistance to oil and hydrocarbon solvents, there is scarcely
an application in which EPDM is totally unsuitable. Because of its
excellent resistance to ozone, sunlight and severe weather conditions,
EPDM is ideal for outdoor service. In general, EPDM, is similar to
butyl but has slightly less susceptibility to contamination.
