EPDM and EPDM plus diaphragms
Overview
EPDM and EPDM plus diaphragms
Ethylene propylene diene monomer (EPDM) is fairly chemical resistant and offers quality performances in applications with repetitive steam-in-place (SIP) cycles.
We currently have two types of EPDM diaphragm available:
- EPDM a relatively low cost material widely used in pharmaceutical applications
- EPDM Plus a Parylene surface treated version which improves the longevity of the EPDM and greatly reduces the stickiness of the diaphragm.
Features and benefits
- All our diaphragms are laser-etched with cure dates and batch numbers, ensuring that they are completely traceable
- Wide temperature range; good in steam applications
- Not suitable for use with solvents or petroleum agents
- Parylene surface treated version available
