Chemical & Material Interaction Analysis

Oils: Diesel Fuel Oil (20, 30, 40, 50) is classified as an aliphatic hydrocarbon / fuel / industrial oil (hydrocarbon permeation and softening in non-oil-resistant polymers and EPDM rubbers). Used in fuel transfer lines, hydraulic power units, lubrication systems, and petrochemical storage. When selecting wetted components for Buna-N, engineers must account for both concentration-dependent chemical attack and thermal stress:

Reaction & Failure Mechanism: Chemically inert interface with no measurable corrosion, polymer chain scission, or elastomeric swell under standard operating conditions.
Material Profile (Buna-N): Workhorse elastomer for petroleum-based hydraulic oils, motor oils, diesel, gasoline, aliphatic hydrocarbons (hexane, heptane), water, and salt brines. However, poor resistance to ozone/weathering and rapidly destroyed by ketones, esters, chlorinated hydrocarbons, aromatic solvents, and strong oxidizing acids.
Application Scope: Common wetted components include hydraulic O-rings, fuel transfer hoses, rotary shaft seals, oil gaskets, and general-purpose industrial pump elastomers.
