FKM (Fluoroelastomer / Viton) vs PE-LD (Low-Density Polyethylene)
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.
PE-LD (Low-Density Polyethylene)
Low-density polyethylene — branched chain structure gives flexibility, transparency, and easy processing. THE film/packaging polymer: cling wrap, carrier bags, squeeze bottles, shrink wrap. Also used for cable insulation, agricultural film, and coatings. Lower density (0.91-0.93) and strength than PE-HD but much more flexible.
