Polyurethane tubing for air has excellent flexibility, high elastic recovery memory effect, flexural resistance, small bending radius, good seismic resistance, wide working temperature and pressure range. It is Suitable for industrial robots, pneumatic tools, assembly plant pneumatic tools, pressure conveying pipelines. Be careful when the ambient temperature or fluid temperature exceeds 60 C. Be careful when the environment or fluid is highly corrosive, such as strong acids, alkalis and solvents. Storage in wet environment for a long time will lead to tube rupture due to hydrolysis.
