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.
