Polyurethane Glass Fiber Composite (PU-GFRP)
Lightweight & High Strength: Density is just 1/6 of steel and 1/2 of aluminum, yet delivers exceptional strength and toughness.
Superior Corrosion Resistance: Excels in harsh environments (salt spray, acids/alkalis, humidity).
High Design Flexibility: Formula adjustments enable customized hardness, elasticity, color, and surface textures to meet specific needs.

Fiberglass reinforced polyurethane composite material is the high-performance composite material based on 20% polyurethane (PU) and 80% fiberglass (GF).

PU fiberglass material combines the excellent toughness, fatigue resistance, impact resistance and processing flexibility of polyurethane resin, as well as the high strength, high rigidity and stability of fiberglass.

Formed through efficient processes such as pultrusion and winding, it features light weight and high strength, thermal insulation, corrosion resistance, and environmental friendliness, and its mechanical properties can be comparable to some metal materials.

Due to its many excellent properties, PU fiberglass composite material is widely used in multiple industrial fields such as door and window curtain wall systems, wind energy, photovoltaics, new energy vehicles, medical equipment, engineering equipment, aerospace, etc., and gradually replaces metal and traditional plastic materials.
