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 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 properties than unsaturated polyester resins.2-5Multiple
