TPU and Injection Molding for the Medical Industry

Legotillverkning

The medical industry places extremely high demands on material performance, safety, and reliability. By combining TPU (thermoplastic polyurethane) with injection molding, medical device manufacturers can produce high-quality components that meet strict regulatory requirements while delivering comfort, durability, and precision.

Why TPU for Medical Applications?

TPU is widely used in medical devices due to its unique combination of flexibility, strength, and biocompatibility. It can be formulated to meet medical-grade standards and is suitable for applications that require both softness and mechanical durability.

Key benefits of TPU:

  • Biocompatible and available in medical-grade formulations

  • Excellent flexibility and elasticity for patient comfort

  • High abrasion and tear resistance

  • Resistance to oils, greases, and common medical chemicals

  • Can withstand repeated sterilization processes

  • Transparent or colored options for functional and aesthetic design

Injection Molding – Precision and Consistency

Injection molding enables the production of complex, high-precision TPU components with consistent quality. The process is ideal for medium- to high-volume manufacturing and supports tight tolerances required for medical devices.

Applications in the Medical Industry

TPU injection-molded components are used in a wide range of medical and healthcare applications where performance, hygiene, and reliability are critical.

Typical applications include:

  • Tubing, catheters, and fluid delivery systems

  • Seals, membranes, and gaskets

  • Wearable medical devices and soft-touch housings

  • Connectors and flexible joints

  • Protective covers and overmolded components

Design Flexibility and Regulatory Compliance

TPU allows for advanced design flexibility, including soft-touch surfaces, transparent parts, and integrated functional features. Injection molding supports repeatable manufacturing processes aligned with medical quality standards such as ISO 13485 and FDA requirements.

A Reliable and Sustainable Material Choice

Many TPU grades are recyclable and support long product lifecycles, helping medical manufacturers reduce waste and improve sustainability without compromising performance or patient safety.

Summary:
TPU combined with injection molding offers a reliable, flexible, and high-performance solution for medical devices. It enables safe, comfortable, and durable components that meet the medical industry’s strict regulatory and functional demands.
