Introduction of Polyester Veil

 With polyester veil, the absorption of resin is more sufficient, and a resin-rich layer is formed on the surface of the FRP to make the surface smooth and beautiful. 

The use of polyester veil in the FRP process can significantly improve the appearance of the product, improve impact and wear resistance, improve corrosion resistance and weather resistance, and make FRP products suitable for more demanding environments.

Our polyester veil is produced using two processes—thermal bonding (hot-rolling) and spunlace. It features uniform fiber distribution and stable quality, and is also more worker-friendly during processing.

Specification of Polyester Veil

The spunlace process can reach a basis weight of up to 100 g/m², and customization is available based on specific requirements.

Features of Polyester Veil

1. Excellent Surface Finish

• Forms a resin-rich surface layer for smooth and clean FRP products

• Reduces air bubbles and surface imperfections during production

2. Protective Surface Layer

• Protects FRP products from abrasion, moisture, and chemical exposure

• Helps prevent delamination between resin and fiberglass reinforcement

3. Improved Mechanical Performance

• Enhances impact resistance and wear resistance

• Helps distribute stress evenly within the composite structure

4. Corrosion & Weather Resistance

• Improves resistance to chemicals and harsh environments

• Suitable for water treatment, chemical plants, marine, and outdoor applications

5. Excellent Resin Compatibility

• Compatible with polyester, vinyl ester, and epoxy resin systems

• Ensures fast wet-out and uniform resin distribution

6. Worker-Friendly Material

• Soft texture and easy handling during processing

• Lower irritation compared with traditional surface materials

7. Flexible & Easy to Process

• Easily conforms to complex shapes and profiles

• Suitable for filament winding and pultrusion processes

8. Low Permeability

• Helps reduce liquid and gas penetration

• Prevents resin leakage during FRP production

9. Optional Flame Retardant Treatment

• Polyester veil itself is not inherently flame retardant

• Flame-retardant powder treatment is available upon request

• Final flame resistance mainly depends on the resin system after impregnation

  
  

Application of Polyester Veil

• Industrial Pipelines: Used in chemical, water treatment, and oil & gas industries for pipelines requiring durability and chemical resistance.

• Construction: Applied in structural components and infrastructure projects where FRP pipes are utilized.

• Marine: Employed in marine environments for piping systems exposed to saltwater and other harsh conditions.

• HVAC Systems: Used in HVAC systems for ducting and other components requiring strength and resistance to environmental factors.
