Who ranks for “engineering plastics”

Key Properties

High Heat Resistance: Continuously usable at temperatures ranging from 100°C up to 150°C (and even higher for specialized types like PEEK). Superior Strength: Exceptional structural integrity, stiffness, and load-bearing capacity that often replace metals, glass, or ceramics. Wear & Chemical Resistance: Low friction coefficients and high resistance to harsh solvents, oils, and physical abrasion. Lightweight: Significantly reduces overall component weight while maintaining durability.

Common Types and Uses

Nylon (PA): Used for gears, bushings, skis, and high-wear mechanical components. Acetal (Delrin): Ideal for precision parts, bearings, and components requiring tight tolerances and dimensional stability. Polycarbonate (PC): Found in safety helmets, protective shields, and optical discs due to high impact toughness. ABS: Widely consumed for automotive bumpers, dashboard trims, and consumer electronics housings. PEEK: Utilized in extreme high-temperature and demanding aerospace or medical applications.
