Polyurethane Hollow Tube is a cast-molded sealing polyurethane elastomer material. It is a hydrolysis resistant polyurethane elastomer material. Besides the excellent characteristics of general-purpose polyurethane elastomer, it also has high hydrolysis resistance in water. Hydrolysis-resistant versions are also highly stable in mineral oils. It has good turning performance, good hydrolysis resistance, good flexibility and resilience. Its long-term use temperature is in the range of -30C~90(℃). Our product use MDI system and TDI system. MDI systems last longer than TDI systems, which can be used for example in metallurgical mining. Compared with general-purpose polyurethane, it has a wider range of applications. The polyurethane hollow tube is a cast-molded polyurethane elastomer material suitable for dieless turning of seals. The seals are also highly stable in mineral oils. It can be used in industries such as metallurgical mining, tunnel excavation machinery and other water applications. The Polyurethane Hollow Tube usually have water temperature resistance up to 90℃. It is suitable for seawater, vegetable oils and pressure-resistant fluids containing phosphate esters, etc.
