Overview

EPDM diaphragms

Ethylene propylene diene monomer (EPDM) is fairly chemical resistant and offers quality performances in applications with repetitive steam-in-place (SIP) cycles. EPDM a relatively low cost material widely used in pharmaceutical applications

Features and benefits

All EPDM 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
