UHMWPE · LYLON®

UHMWPE fibre LYLON — lighter than water, stronger than steel

Ultra-high molecular weight polyethylene (1.5–5.7 M) processed into fibre by gel spinning with multi-stage hot drawing. The only dry gel-spinning process in China. Combines record specific strength with full chemical inertness.

0.97 g/cm³density below water — the fibre floats

30–45 g/dentenacity — up to 15× steel by weight

950–1600g/den — elastic modulus

100 %strength retention after 6 months in seawater, acids, alkalis and fuels

Material limitation: service temperature up to ~80 °C, melting point ≈147 °C.

PARA-ARAMID · ARAMID 1414

Para-aramid (PPTA) — the “golden fibre”

Poly-p-phenylene terephthalamide: rigid aromatic chains with ≥85% amide bonds between benzene rings. Spun from a liquid-crystal solution via dry-jet wet spinning. The world leader in heat resistance among high-performance fibres.

20–23 g/dentenacity — 3× steel, 5× by weight

>430 °Cdecomposition temperature; Tg above 270 °C

LOI 28–32does not burn in air, does not melt, self-extinguishing

1.44 g/cm³5.5× lighter than steel at comparable strength
