Fiberglass Reinforcements
17 grades across 6 application scenes — wind blade, marine FRP, pultrusion, 5G PCB & electronics, construction GRC, aerospace / ballistic — sourced from the Anyang fiberglass cluster.
- •Anyang in central Henan is China's second-largest fiberglass production cluster, anchored by Jushi's Anyang sub-plant, Anyang Goldensun (光远新材) for 5G PCB grades, and CNBM Anyang (中材高新). Combined output covers ~25% of China's E-glass capacity and most of the country's electronic-grade (Low-Dk) fiber.
- •This hub covers the full procurement spectrum: E-glass and ECR-glass for general FRP and wind blade structural layers; UD and biaxial non-crimp fabrics for wind blade spar caps and shear webs; woven roving and chopped strand mat for marine and decorative hand layup; Low-Dk fabrics 1080/2116 for 5G base station and millimeter-wave PCBs; AR-glass for GRC cement reinforcement; S-2 glass for aerospace and ballistic.
- •All grades ship with COA, MSDS, and ISO 9001 certification options. Free samples (1–5 kg) for qualified projects. Typical lead time 7–14 days ex-works for in-stock grades; 30–45 days for custom tex / sizing / width.

Frequently Asked Questions
▶E-glass vs ECR-glass — what's the difference and when do I need ECR?
ECR is boron-free with much better acid resistance; required for offshore wind blades and chemical-service FRP tanks.

▶What does “2400 tex” mean and where is this direct roving used in a wind blade?
Tex = grams per kilometer of yarn. 2400 tex is the wind industry's workhorse, used in the spar cap and root buildup.

▶Low-Dk glass fabric 1080 vs 2116 — how do I pick for my 5G PCB layer stack?
1080 is thinner (~47 g/m²) for high-density interconnect signal layers; 2116 (~104 g/m²) for thicker dielectric and stiffness layers.

▶Why does AR-glass require zirconia ≥ 16.7%? Is “AR-glass” with lower ZrO₂ legitimate?
EN 15422 sets ZrO₂ ≥16.7% as the minimum for GRC service life. Lower-ZrO₂ “AR-glass” degrades within 5-10 years in cement.

▶S-glass vs E-glass — how much higher is the strength, and when is the cost premium justified?
S-2 glass tensile strength is ~30% higher (4500 vs 3400 MPa) and modulus ~15% higher; cost is 4-6x. Justified only for aerospace and ballistic.

▶Direct roving vs assembled roving — which one for my process?
Direct roving = single-strand drawn directly to final tex. Assembled = multiple strands twisted together. Direct is standard for modern winding and pultrusion.
