Product Overview
Glass Fiber Surface Mat is a non-woven surface veil manufactured by wet-laid process, utilizing E-glass fibers (SiO₂ 52-56%, Al₂O₃ 12-16%) chopped to micro-diameters (9-13μm), randomly distributed and bonded with emulsion binders (e.g., acrylic resin or PVAc).
Core Advantages
- Conformability: High drapability for complex contours (e.g., boat hulls, automotive bumpers), reducing bubble formation by >40%.
- Mechanical Integrity: Tensile strength up to 220N/50mm (EC340 grade), wet strength retention >90%.
- Safety Compliance: Non-combustible (Fire Class A1), acid/alkali-resistant (except HF), SGS-certified eco-friendly.
Application Fields
| Industry | Key Applications | Functional Value |
| Construction | Pipe/tank linings, gypsum board reinforcement | Chemical resistance; extends service life to ≥20 years |
| Transportation | Gel coat layers for boats, automotive bumpers | 25% weight reduction; superior surface finish |
| Electronics & Electrical | PCB copper-clad laminates, transformer insulation | Dielectric strength ≥15kV/mm; circuit safety assurance |
| Energy & Environment | Flue gas filtration, desulfurization tower linings | Temperature resistance (280℃); 99.5% filtration efficiency |

Customization: Grammage (20-340 g/m²), width (up to 3,600 mm), binder type (emulsion/powder), and alkali content (E-glass or medium-alkali for acid resistance).
Performance: Surface roughness ≤0.8μm after molding; resin uptake rate ≥95%.
Packaging Method
Triple-layer industrial-grade protection ensures damage-free transit:
- Roll Configuration: Material wound onto Ø 76-100mm kraft paper tubes with heat-sealed edges to prevent fiber shedding. Standard dimensions: Width 1,000-3,600 mm; length 200-1,000 m (adjustable by grammage).
- Sealed Encapsulation: Inner layer: Anti-static PE film moisture barrier. Outer layer: 5-ply corrugated box or woven bag labeled "↑ Moisture-Proof, Fragile".
- Shipping Units: Palletized Loads: 8-12 rolls vertically or 6-8 rolls horizontally per wooden pallet (1.2 m max. height), stretch-film secured. Container Capacity: 18-22 pallets per 40HQ container (~20-25 tons).
Storage Guidelines
Strict environmental control to maintain 12-month shelf life:
- Environmental Requirements: Temperature: 15-35°C (avoid <5°C brittleness or >40°C binder degradation). Humidity: 35-65% RH (dehumidified warehouses; no outdoor storage).
- Handling Protocols: Rolls stored vertically on pallets; stacking ≤3 layers (flat storage requires cushioning boards). Isolate from UV radiation, acidic fumes, and solvents (install blackout curtains).
- Post-Opening: Consume within 72 hours; reseal unused material in heat-sealed bags with opening time labeled.
Service Commitment
Custom Solutions: Tailored grammage, width, and alkali content (e.g., medium-alkali for acid environments).
Quality Assurance: Batch-specific ISO test reports (tensile strength, resin uptake, binder solubility).
Global Logistics: FOB/CIF terms; moisture-controlled containers + GPS tracking.
