The product boasts excellent toughness, with processed and cut edges of polyurethane composite materials showing minimal to no microcracks. The surface is smooth and delicate, with high strength and low porosity, which is beneficial for subsequent processing such as drilling, machining, and assembly. Compared to unsaturated polyester, vinylester, and other resin pulled products, polyurethane pulled products offer significant advantages in terms of ease of on-site construction and service life.
