Ethylene-propylene (EPM/EPDM)
Working Temperature Range :-45℃ to +120℃
EPDM has good resistance to ozone ageing and weathering, water and steam, Dilute acid, alkalies ketones, alcohol, fire retardment hydraulic fluids and hydraulic brakes fluids, this elastomer must not come in contact with mineral oils and greases.
Chemical properties
They display resistance to aliphatic phosphate-ester hydraulic fluids, acids, alkalis, salt solutions, alcohols, glycols and silicone oils.Often used with steam raising plant. They must not be used with mineral oils or di-ester based lubricants.
Hardness:
Hardness is a physical measure, which is compression deformation degree. Shores hardness is tested by shores durometer, unit " degree"; Two discription: A&D, under 90 degree showed by shores A, over 90 degree showed by shores D. Normal rubber hardness unit is HS and IRHD, value of shores A is same with IRHD.
| Pressure | Suggest Hardness |
| 0-8Mpa | 40-70 Shore A |
| 8-10Mpa | 75 Shore A |
| 10-15Mpa | 80 Shore A |
| 15-20Mpa | 85 Shore A |
| 20-30Mpa | 90 Shore A |
| Over 30Mpa | Use with back up ring or change a material |
