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.
