Rubber Expansion Joints Corrosion Resistance Data Sheet: Selecting the Perfect Solution for Demanding Applications

In piping systems for chemical processing, pharmaceuticals, marine engineering, water treatment, and various industrial sectors, corrosion is a primary cause of equipment failure, unscheduled downtime, and safety hazards. Choosing a rubber expansion joint with superior corrosion resistance is a critical decision for ensuring long-term system reliability and reducing total lifecycle costs.

This detailed corrosion resistance data sheet provides a clear comparison of different elastomer materials, empowering you to make the optimal selection for your specific service conditions.

Chemical Resistance Comparison Data Sheet for Rubber Expansion Joint Materials

Elastomer Material	Abbreviation	Key Chemical & Corrosion Resistance	Typical Suitable Media	Media to Avoid	Temp. Range (°C)	Primary Application Scenarios
EPDM Rubber	EPDM	Excellent resistance to strong acids, alkalis, hot water, steam, ozone. Superior aging resistance.	Phosphoric acid, dilute sulfuric acid, sodium hydroxide, superheated steam, glycol coolants.	All oils, fats, hydrocarbons (gasoline, benzene).	-40 ~ +130	Power plants, chemical plants, HVAC systems. Ideal for most polar chemicals.
Fluorocarbon Rubber	FKM/Viton®	"King of Chemical Resistance." Resists strong oxidizing acids, oils, hydrocarbons, and most organic solvents.	Concentrated sulfuric/nitric acid, hydraulic oils, fuels, diverse organic chemicals.	Ketones, esters, hot ammonia.	-20 ~ +200	Extreme chemical transfer, aerospace, high-end manufacturing.
Nitrile Rubber	NBR	Excellent oil and fuel resistance. Resists petroleum-based fluids and greases.	Fuels, lubricating oils, hydraulic fluids, vegetable oils.	Strong oxidizing acids, ozone, ketones, esters.	-30 ~ +110	Fuel lines, refineries, hydraulic systems handling oil-based media.
Neoprene Rubber	CR	Balanced all-around properties. Resists moderate acids/alkalis, weathering, and ozone.	Seawater, dilute acids/alkalis, air, ozone-rich environments.	Strong oxidizing acids, esters, chlorinated hydrocarbons.	-40 ~ +100	Shipbuilding, coastal installations, general industrial piping with broad compatibility.
Natural Rubber	NR	High resilience. Resists weak acids/alkalis and water.	Cold water, seawater, air, non-oily slurries.	All oils, ozone, strong acids.	-50 ~ +80	General water supply, circulating water in non-corrosive, low-pressure environments.

Key Takeaway: The corrosion resistance of a rubber expansion joint is paramount and must be precisely matched to the specific fluid in your pipeline. Incorrect material selection leads to rapid corrosion, swelling, cracking, and joint failure.
