This means that we can provide various size of polyurethane casting tubes ranging from 0 to 1600 mm.Our tube material size is extremely rich, allowing customers to choose to the most satisfactory size.
We have developed a polyurethane castable pipe C500H with high temperature resistance, hydrolysis resistance and oil resistance, The C500H is a hydrolysis-resistant casting polyurethane elastomer. It combines the good mechanical properties with a high resistance to hydrolysis (degradation in water). it is stable in water up to +90 °C and has an outstanding stability in mineral oil.
We developed a hydrolysis resistant polyurethane cast pipe material C700 due to its good mechanical properties and hydrolysis resistant. It can be used in Rod Seals, Piston Seals, It combines the good mechanical properties with a high resistance to hydrolysis (degradation in water). It is stable in water up to +90 °C and has an outstanding stability in most common hydraulic fluids.
We have developed a series of TPU of high temperature resistant system, and these TPU are developed and synthesized based on PPDI. Compared with THE TPU of MDI system, the TPU of these PPDI systems has better resilience, better wear resistance, better high temperature resistance, better dynamic performance, especially in high frequency working environment, showing excellent service life. A large number of experimental data and market feedback show that this material has excellent service life in crushing hammers and excavators.
In 2021, I moved to the factory I bought and added many pouring machines, which increased the capacity and varieties of pouring polyurethane pipe material.
MDI series of polyurethane seals elastomer TPU scheme, P793S for polyether system, low temperature resistance, resilience, flexibility are excellent, suitable for most of the use of temperature is not high in the industrial field. P600 is a polycaprolactone system with excellent mechanical properties and is a standard material for hydraulic seals. P500 is both oil resistance and hydrolysis resistance, is a more widely used environment sealing material.
