High Strength and High Stiffness Pultruded Fiberglass Profiles with Polyurethane Resin

Product Details

Pulwell produces pultruded FRP profiles utilizing polyurethane resin (PUR) technology called GRPU (fiberglass reinforced polyurethane). Pultruded FRP profiles from PU resin have superior tensile strength, impact resistance, and abrasion resistance compared with composites based on unsaturated polyester and vinyl ester resins


Benefits: Polyurethane 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. Higher fiber volume
4. Higher specific strength and stiffness
5. Reduced wall thickness
6. Excellent impact resistance
7 .Excellent abrasion resistance
8. Excellent screw pull-out strength
9. Excellent corrosion resistance
10. No Styrene emissions, no peroxides, NO VOCs


Typical applications of PUR pultruded composite profiles: cross-arms, electrical poles, cooling tower parts, sheet piles, cable trays, ladder rails, window lineal, lintels, door frames, solar panel support frames and etc.
