Chemical & Material Interaction Analysis
Biodiesel (B100) 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 Viton, 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 (Viton): Exceptional resistance to aliphatic and aromatic hydrocarbons, petroleum oils, concentrated mineral acids, and halogenated solvents at elevated temperatures. However, severely attacked by polar oxygenated solvents (acetone, MEK, ethyl acetate, THF), anhydrous ammonia, primary amines, and hot concentrated caustic soda via dehydrofluorination.
- Application Scope: Common wetted components include O-ring static/dynamic seals, pump diaphragms, valve seats, flange gaskets, and chemical transfer hose liners.
