FKM (Fluoroelastomer / Viton) vs PP-H (Polypropylene Homopolymer)
Side-by-side chemical composition and mechanical property comparison.
Overview
FKM (Fluoroelastomer / Viton)
Fluoroelastomer — THE high-temperature and chemical-resistant rubber. Outstanding resistance to oils, fuels, acids, and solvents at temperatures up to 200°C (short-term 230°C). Fluorine content (64-70%) determines chemical resistance. Trade names: Viton (Chemours), Tecnoflon (Solvay), Dai-El (Daikin). 5-10x more expensive than NBR. Used for aerospace fuel seals, chemical process seals, automotive fuel injector O-rings, semiconductor processing, and any seal exposed to aggressive chemicals at high temperature.
PP-H (Polypropylene Homopolymer)
Polypropylene Homopolymer — the lightest common engineering plastic (0.905 g/cm³). Excellent chemical resistance (esp. to acids and bases), good fatigue resistance (integral living hinges), and low moisture absorption. Becomes brittle below 0°C. Used for chemical tanks, HVAC ducts, pump housings, food containers, automotive battery cases, and medical lab equipment.
