Four glass fiber families — alkali-resistant (AR), high-strength (S), high-modulus (M) and low-Dk (D) — used in construction reinforcement, wind blades, aerospace and electronic substrates.
AR alkali-resistant (ZrO₂ ≥16%), S high-strength, M high-modulus and D low-Dk fibers — covering mechanical, electrical and chemical requirements.
Sizing systems matched to epoxy, vinyl ester, phenolic, PP and PA resins; interfacial bond strength improved by 30–50%.
Roving, assembled roving, chopped strand, continuous mat, surfacing mat, woven roving and combo mat — 12 product forms in total.
ISO 9001 certified lines. Every batch ships with a COA; key indicators CV ≤5%. 200 t in stock, 3–7 day lead time.
