In addition, the TPV supplier was not providing sufficient quantities of the material consistently, threatening the manufacturer’s ability to meet its own customer’s needs on time. THE SOLUTION In the course of their research into material options, the manufacturer’s team invited Avient to suggest options for an alternative TPV based on its global reputation for superior products and service. THE IMPACT Avient’s expertise in materials for medical device applications helped this customer make a smooth transition to the GLS TPV.
