Eco Friendly Standard Chopped Strand Mat Non Woven Fiberglass Mat For Marine Panels

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.

• 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.

Compliant with ISO 3374/3344/1887 standards, standard and customizable grades are listed below:

• Grammage (100-1,200 g/m²)
• Width (up to 3,600 mm)
• Binder type (powder/emulsion)
• Alkali content (E-glass or medium-alkali for acid resistance)

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).

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.

• Custom Solutions: Tailored grammage, width, binder type, and alkali content.
• Quality Assurance: ISO-compliant test reports with each batch (tensile strength, resin compatibility).
• Global Logistics: FOB/CIF terms; moisture-controlled container shipping + GPS tracking.
