Types of Resin Used in FRP Profiles

1. Unsaturated Polyester Resin (UPR)

Unsaturated polyester resin is the most commonly used resin in FRP profiles due to its cost-effectiveness and fast curing properties.

• Advantages: Low cost, good processability, fast curing
• Disadvantages: Moderate corrosion and weather resistance
• Applications: Structural profiles, handrails, cable trays

2. Vinyl Ester Resin

Vinyl ester resin combines the processability of polyester with the corrosion resistance of epoxy, making it ideal for harsh environments.

• Advantages: Excellent chemical resistance, high strength and flexibility
• Disadvantages: Higher cost than UPR
• Applications: Chemical tanks, marine structures, industrial platforms

3. Epoxy Resin

Epoxy resin provides the highest mechanical strength and superior electrical insulation, commonly used in high-performance FRP components.

• Advantages: Excellent mechanical and adhesive properties, great electrical insulation
• Disadvantages: Higher cost, slower curing time
• Applications: Electrical insulators, aerospace components

4. Phenolic Resin

Phenolic resin is known for its flame resistance and low smoke production, suitable for fire-safe applications.

• Advantages: Naturally flame-retardant, high heat resistance
• Disadvantages: Brittle, lower mechanical strength
• Applications: Subway panels, tunnels, fireproof FRP profiles
