Avoid Rubber Hose Failure Which Material is Resistant to Hexane?

Why Do Rubber Tube Deteriorate When Exposed to Hexane (Hexane) and What Type Should Be Used Instead?

Causes of Rubber Tube Deterioration When Exposed to Hexane
Hexane is a solvent belonging to the hydrocarbon group, known for its ability to dissolve fats and certain plastics. It significantly affects certain types of rubber hoses, causing them to degrade rapidly. Specifically, NR (Natural Rubber), SBR (Styrene-Butadiene Rubber), EPDM (Ethylene Propylene Diene Monomer), and Silicone Rubber have low resistance to oils and hydrocarbon solvents. When exposed to hexane, these rubbers absorb the chemical, leading to swelling, softening, and ultimately cracking or failure.
What Type of Rubber Tube Should Be Used Instead?
If your application involves hexane, it is essential to choose a rubber Tube with excellent resistance to oils and hydrocarbon solvents, such as:
1. Nitrile Rubber Tube (NBR - Nitrile Rubber)
Highly resistant to hexane, petroleum oils, and hydrocarbon solvents.
Suitable for petrochemical industries and liquid transmission systems exposed to hydrocarbons.
2. Viton Rubber Tube (FKM - Fluoroelastomer)
Superior resistance to hexane and aggressive chemicals.
Withstands high temperatures and offers excellent durability against hydrocarbon solvent corrosion.
3. PTFE Tube (Teflon)
Exceptional resistance to hexane, highly corrosive chemicals, and extreme temperatures.
Non-absorbent to liquids, making it long-lasting and resistant to degradation.
For applications involving Hexane (Hexane), avoid rubber Tubes made from NR, S

BR, EPDM, and Silicone. Instead, opt for NBR, FKM, or PTFE hoses to ensure longevity, prevent degradation, and maintain safety in operations.
