| Characteristics of EPDM |
|
| EPDM
is synthetic rubber made by polymerization of ethylene, propylene and/or
non-conjugated |
| diene with residual
unsaturation in the side chain. |
| It can be vulcanized by
sulfur,Peroxide, |
| Phenol resin and Radiation
etc.; |
| especially the diene is
introduced to allow sulfur vulcanization. |
|
| EPDM
is particularly excellent in ozone resistance,weather resistance, heat
resistance, |
| chemical resistance and its
specific gravity is lower than that of synthetic rubbers. |
| It is very economical because
of possibility of high filter/processing oil loading. |
|
| EPDM
is used for varieties of applicatons such as sealings, tire tubes, hoses,
electric |
| wires/cables, industrials
goods, polyolefin modifiers, etc. |
