EPDM or Ethylene
Propylene Diene Monomer can be vulcanized by
using conventional method of using sulphur
or by dicumyl peroxide (DCP). It has an
excellent operating temperature range of
-45°C to + 120°C.It is highly recommended
for out door uses as it extremely resistant
to oxidation, U.V. Rays and Ozone due to its
highly saturated polymer chain. However,
EPDM does not have good oil resistance or
adhesion properties. It is resistant to many
chemicals and solvents and shows good
resistance to many corrosive chemicals. It
is impermeable to water and is used as
roofing sheet and waterproffing membrance.
