Benefits: Urethane is 40% stiffer than Polyester, this allows for a stiffer profile or reduction in profile thickness by about 25% which reduces the profile weight and maintains the same stiffness as Polyester resin technology.
Advantages of Polyurethane vs Polyester Resins
1. Increased Strength
2. Improved Transverse properties
3. Highest fiber volume
4. Higher specific strength and stiffness
5. Reduced wall thickness (weight savings)
6. Stronger profiles spanning greater distances
7. Excellent impact resistance (Polyester has poor impact resistance in comparison)
8. Excellent abrasion resistance
9. Easy fabrication
10. Excellent screw pull out strength (compared to traditional polyester pultrusion
11. Much lower smoke generation than Polyester or Vinyl Ester
12. Excellent corrosion resistance
13. No Styrene emissions, no peroxides, NO VOCs
