Product Overview: Glass Fiber Chopped Strand Mat (CSM)
Glass Fiber Chopped Strand Mat (CSM) is a non-woven reinforcement material composed of randomly distributed E-glass fibers (SiO₂ 52-56%, Al₂O₃ 12-16%) chopped to 50mm lengths, bonded by powder or emulsion binders (e.g., polyester powder). Its isotropic structure ensures uniform resin permeability and mechanical strength in all directions, making it ideal for hand lay-up, compression molding, and resin infusion processes.
Core Properties
- Resin Compatibility: Rapid saturation with unsaturated polyester, epoxy, and vinyl ester resins (impregnation time ≤60 sec), reducing bubble retention by 40%.
- Mechanical Performance: Tensile strength up to 260N/150mm (EMC1200), wet strength retention >90%.
- Safety Compliance: Non-combustible (Fire Class A1), corrosion-resistant (except HF and concentrated H₃PO₄), SGS-certified eco-friendly.
Application Fields
| Industry | Key Applications | Functional Advantages |
| Transportation | Automotive roofs, bumpers, aircraft interiors, boat hulls, decks | Conforms to complex curves; 30% weight reduction |
| Construction | FRP roofing panels, chemical tanks, pipes, cooling towers, sanitary ware | Corrosion resistance; service life ≥20 years |
| Energy & Environment | Wind turbine blades, wastewater treatment equipment, chemical storage tanks | High fatigue resistance; wet strength retention |
| Consumer Goods | Sports equipment, model prototypes, FRP molds, recreational facilities | Smooth surface finish (Ra ≤0.8μm); high resin compatibility |

Notes:
- Customization: Grammage (100-1,200 g/m²), width (up to 3,600 mm), binder type (powder/emulsion), and alkali content (E-glass or medium-alkali for acid resistance).
- Quality Control: Batch-specific ISO test reports for tensile strength, resin uptake rate, and binder solubility.
Packaging Method
Industrial-grade triple-layer protection ensures zero damage during transit:
- Roll Configuration: Material wound onto Ø 76-100mm kraft paper tubes with edge sealing to prevent fiber shedding. Standard dimensions: Width 1,040 -3,600 mm; length 20 -40 m (adjustable by grammage).
- Sealed Encapsulation: Inner layer: Anti-static PE film moisture barrier. Outer layer: Reinforced 5-ply corrugated box labeled "↑ Moisture-Proof, Handle with Care".
- Shipping Units: Palletized Loads: 12-16 rolls vertically or 6-9 rolls horizontally per wooden pallet (max. height 1.2 m), secured with stretch film. Container Capacity: 18-22 pallets per 40HQ container (approx. 25 tons).
Storage Guidelines
Optimal conditions to maintain 12-month shelf life:
- Environmental Control: Temperature: 15-35°C (avoid freezing or >40°C to prevent binder degradation). Humidity: 35-65% RH (storage in ventilated, shaded warehouses; no outdoor stacking).
- Handling Protocols: Rolls stored vertically or flat on pallets; stacking ≤3 layers to avoid deformation. Isolate from chemicals (acidic fumes), UV radiation, and sharp objects.
- Post-Opening: Use within 72 hours of unsealing; reseal unused material in heat-sealed bags.
Service Commitment
Custom Solutions: Tailored grammage, width, binder type, and alkali content (e.g., medium-alkali for acid resistance).
Quality Assurance: ISO-compliant test reports with each batch (tensile strength, resin compatibility).
Global Logistics: FOB/CIF terms; moisture-controlled container shipping + GPS tracking.
