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.

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

Durable LYLON (2025): >90% strength after 3 years in deep-sea cages; cages withstood a direct category-17 typhoon hit without damage. Full grade table 20D–4800D on request.

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.

Heat resistance: 95% strength after 500 h at 160 °C; 75% after 100 h at 200 °C. Ballistic products meet GA Class II–III (China) protection levels.

Material limitation: UV sensitivity — outdoor use requires protection from light.
