Polyurethane extrusion speed up to 1.5m/sProduction speed is relatively fast. 
Hastens superior to unsaturated resin systems.
Polyurethane pulled yarn content up to 83%At the same time achieving the same performance indicators, the thickness of its products is approximately half that of the unsaturated resin system.
The main components are polyurethane and glass fiber. The primary material is thermosetting polyurethane. This product boasts high tensile strength, impact resistance, and corrosion resistance. Its typical tensile strength is approximately... 880kg/cm2, approximately tensile modulus30230kg/cm2Tensile elongation at break7.5%Above. Foamed polyurethane composite materials can reduce weight by up to 50% in the same volume.25%Compared to other resins like unsaturated polyester and vinyl ester, polyurethane significantly enhances the physical properties of the product. Polyurethane boasts higher strength and stiffness compared to unsaturated polyester resins.2-5Multiple;
