Product Definition

Polyester surface veil is a 100% modified polyester fiber non-woven fabric manufactured through hydro-entanglement technology. Designed as the critical surface enhancement layer for FRP composites, it forms a high-resin-permeability barrier that significantly improves corrosion resistance, surface finish, and weather durability.

Core Advantages
  • Exceptional Chemical Resistance
    • Withstands highly corrosive media like hydrofluoric acid (HF) (superior to glass fibers), ideal for chemical storage tanks and acid digestion chambers
    • Validated by ISO 28721-3 for chemical solvent resistance.
  • Rapid Resin Penetration
    • Fiber-modified surface accelerates resin saturation by 30%, eliminating bubbles, white spots, and fiber print-through for uniform resin-rich surfaces
  • Environmental Durability
    • UV Stability: Blocks photodegradation, extending outdoor service life (e.g., fencing, wind turbine blades)
    • Thermal Endurance: Continuous service at 230°C, peak tolerance at 280°C
  • Operator & Process Safety
    • Soft fibers prevent skin irritation vs. glass fiber splinters; excellent conformability to complex mold geometries
Global Applications
Corrosion Engineering
  • HF Storage Tanks & Wastewater Liners: 50% longer lifespan than traditional materials
  • Chemical Pipeline Liners: Leak-proof performance certified to ISO 28721-3.
Infrastructure & Transportation
  • FRP Railings/Auto Bumpers: Mirror-like finish with impact resistance; complies with EN 45545-2 fire standards
  • Mass Transit Interior Panels: Fiber-free surface ensures human-contact safety.
Renewable Energy
  • Wind Blade Surface Layer: Zero chalking after 3,000 hrs QUV testing (ASTM G154)
  • Desulfurizer Towers: Resists sulfide corrosion (-40°C to 230°C).
High-Precision Manufacturing
  • Aerospace Components: Dimensional stability for tight-tolerance assemblies.
  • Reverse Osmosis Housings: Mashes fabric patterns, enhances hydraulic pressure resistance.
