Discover Why Polymers Like Texin® Change the World

Medical Benefits of Texin® A Thermoplastic Polyurethane (TPU)

Did you know that thermoplastic polyurethane (TPU) can be used for a wide variety of applications in the medical industry? This high-performance elastomer has multiple medical benefits which allow it to be used for:

  • Thin walled, flexible tubing
  • Luers, connectors and stopcocks
  • Catheters
  • Films and fabric coatings
  • Component housings
  • Soft touch grips
  • Healthcare devices
  • Wearables

As a worldwide leader in providing engineering polymers at the most competitive prices, Amco Polymers is more than familiar with TPU and how Texin®, one of its high-performance medical grades from Covestro, can help support our customers. Read on to learn about the benefits of this thermoplastic elastomer or healthcare.


Before selecting a material for developing your medical application, you have to know if it requires biocompatibility – the ability to perform when in contact with living systems or tissue. This unique quality is essential to the design and implementation of most medical devices and components. To determine if a material meets those standards, you’ll want to check if it is ISO 10993-1 certified.

Texin®, a biocompatible grade of TPU developed by Covestro, meets certain test requirements of ISO 10993-1: “Biological Evaluation of Health Care Devices” for categories including (1) skin contact (2) up to 24 hours contact with circulating blood, tissue, bone, and dentin, and (3) up to 30 days contact with mucosal membrane, compromised surfaces, and blood path, indirect.

Always be sure that you never ask a material to exceed its ISO requirements. If you’re looking for a material that meets more demanding needs than what we listed above, you will want to look into an alternative to TPU.


Another reason that medical grades of TPU like Texin® are able to be used for multiple medical applications is their sterilization-compatibility. When using medical devices—especially reusable ones—sterilizing them regularly prevents exposing patients and staff to the growth and spread of diseases.

Covestro’s Texin® can be sterilized by ethylene oxide gas, dry heat, E-beam and Gamma irradiation—though Gramma irradiation may change the color of the material. This material cannot be sterilized through steam autoclaving or boiling water, however, so be sure you’re sticking to the above types of sterilization.

Excellent Resistances

Healthcare environments are demanding on materials, and without proper resistances, medical devices won’t always last or perform well. Covestro’s Texin® has several resistances that allow it to perform well in medical applications.

The chemical resistances of Texin® give an application resistance to lipids as well as cleaning and disinfectant agents. Additionally, Texin®’s microbe resistance resists the growth of algae, fungi, mold and bacteria. If you’re using Texin® for tubing, its kink resistance also helps prevent tube blockages. Finally, as a TPU, Texin® is able to keep up to the demands of medical applications through excellent tear, wear, stain and abrasion resistances.

Excellent Strength and Elastic Properties

Even at minimal wall thickness, Texin® has excellent tensile strength and unique elastic properties. As a thermoplastic polyurethane, Texin® has “rubbery” qualities that other polymers don’t. One of these is TPU’s “elastic memory,” which maintains tension and makes the material unlikely to leak at joints.

These elastic properties also make TPU beneficial for patient comfort. Texin®’s High Moisture Vapor Transmission Rate (MVTR) lets it be used for comfortable gowns, linens, drapes and breathable wound dressings as a fabric coating.


Visibility is important for the success of many medical devices, and Texin®’s high clarity provides enhanced visual observation for end-users. As with most thermoplastics, however, additives can alter material properties to achieve different results. If desired, this TPU can be made radio-opaque with barium sulphate.

While we provide the highest quality TPU to a large variety of industries besides medical and healthcare, what they all have in common is their dependence on our value, support, assistance and consistent reliability.
