We specialize in manufacturing super developing tubes (PU, PEBAX, nylon) with tungsten content up to 80%. Traditional catheters are marked with gold or platinum rings to increase visibility in fluoroscopy. As a new alternative material, tungsten has more significant advantages. Through the innovative way of integration with thermoplastic materials, tungsten can maintain the development effect and be smoother. In addition, we provide hydrophilic coating services, so that your products show the best performance.
