The Importance of Moisture Content and Viscosity for Medical Devices

Reduce molding defects! Moisture content and viscosity management essential for precision molding of medical devices.

In the precision molding of the medical device industry, product quality and safety are the top priorities. Molding defects can lead to product malfunctions and risks to patients, necessitating thorough countermeasures. Particularly when using materials such as thermoplastic polyurethane (TPU), the moisture content of the pellets significantly affects moldability. Excess moisture can cause bubbles and shape defects, potentially compromising product quality. Therefore, to quantitatively evaluate the impact of the drying degree of TPU pellets on moldability, we measured the moisture content and viscosity of both undried and dried TPU pellets and compared the appearance of the extrudate (strand). The details are published on our company website. Please click the link below to view. [Application Scenarios] - Medical tubes - Precision connectors - Implant components [Benefits of Implementation] - Reduction of molding defect rates - Improvement of product quality - Enhancement of yield
