EPDM vs FKM: Which Material is Better for Industrial Steam Applications?

EPDM vs FKM for Industrial Steam Applications

Material Overview

Selecting the right elastomer for steam applications requires evaluating temperature resistance, compression set, and chemical compatibility. EPDM (Ethylene Propylene Diene Monomer) and FKM (Fluorocarbon Rubber) are common choices, but their performance differs significantly under steam conditions.

Key Technical Parameters

Both materials must comply with IATF 16949 for automotive-grade quality, ASTM D2000 for material classification, and ISO 3601 for hydraulic seal standards. Below are critical performance metrics:

Parameter	EPDM	FKM
Temperature Range	-50°C to +150°C (short-term 175°C)	-20°C to +200°C (short-term 230°C)
Compression Set (ASTM D395, 22h @ 150°C)	15-25%	20-35%
Steam Resistance (Saturated, 150°C)	Excellent (low swell)	Good (moderate degradation)
