SHANGHAI – September 25, 2024 – Avient Corporation, a leading provider of specialized and sustainable materials solutions and services, will exhibit its extensive portfolio of medical-grade materials and solutions for healthcare applications at Medtec China 2024, including the announcement of newly expanded manufacturing for its NEU™ Custom Capabilities and NEUSoft™ Thermoplastics Polyurethane (TPU) solution for catheter applications in China. Newly Expanded Manufacturing of NEU™ Custom Capabilities and NEUSoft™ Thermoplastics Polyurethanes for catheter applications: now produced in Suzhou, China, offering customized services and rapid response times to customers from Asia Pacific, a series of ultra-soft TPUs for short-term in-vivo applications that are available in custom colors with excellent ultraviolet (UV) stability and barrier properties, offer good elasticity, resistance to abrasions and tears, barrier properties, and melt strength for use in a host of catheter applications, including cardiovascular, intravenous, and other specialty segments . Customized colors and solutions are also available to meet specific needs.

They are difficult and time-consuming to install, require a number of different par ts, and wear out rapidly. We wanted to make it easier for our customers to create durable piping systems by developing a plastic flapper valve that could be easily fused onto polyethylene (PE) pipe. Avient’s experts customized a Gravi-Tech formulation that met our exact requirements.”

What’s effective for Avient has also proven to be desirable and effective for our customers. In launching Avient’s LSS Customer First service, we have been training our customers in lean principles, who then identify and implement process improvement projects in their operations.
