PA66 GF30
Polyamide 66 with 30% short glass fiber — stronger and more heat-resistant than PA6 GF30 due to higher-Tm base polymer. UTS ~190 MPa dry, HDT ~250°C. THE automotive under-hood material for structural brackets. Trade names include Ultramid A3WG6 (BASF), Zytel 70G30 (DuPont), Durethan AKV 30 (LANXESS), Technyl A218 V30 (Domo). Used for engine brackets, radiator end tanks, air intake manifolds, and electrical connectors.

EPDM (Ethylene Propylene Diene Rubber)
Ethylene propylene diene monomer rubber — THE outdoor/weather elastomer. Saturated backbone gives outstanding ozone, UV, and weathering resistance. Excellent resistance to steam, hot water, and polar solvents. NOT resistant to oils/fuels (opposite of NBR). Good electrical insulation. ρ 0.85-1.3 (lightest common rubber). Used for automotive door/window seals, roofing membranes, radiator hoses, HVAC gaskets, and pond liners.
Epoxy/Carbon Fiber (CFRP)
Carbon fiber reinforced epoxy — the benchmark structural composite material. Unidirectional ply: tensile strength 1500–2000 MPa, modulus 120–150 GPa at density 1.55 g/cm³ (5x stronger than steel at 1/5 the weight). Quasi-isotropic layup: UTS ~600 MPa, E ~50 GPa. Autoclave-cured prepreg (aerospace) or infusion/RTM (industrial). Used in aerospace primary structures (fuselage, wings), Formula 1 chassis, bicycle frames, wind turbine blades, pressure vessels (Type IV) and high-end sporting goods. Fiber types: T300, T700, T800, M40J, M55J.
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.
