The Changhua site is Covestro’s second facility worldwide, after New Martinsville in North America, to be qualified to produce medical-grade TPU. The localized production of these high-standard materials in Asia Pacific enables more flexible and efficient regional supply to meet growing demand.

Localized production that meets global standards

Produced at the Changhua site in accordance with Good Manufacturing Practice (GMP) principles, the new Desmopan Rx grades are engineered to meet stringent international requirements for medical applications and minimize contamination risks.

The materials are verified for biocompatibility in accordance with ISO 10993 and China’s YY/T 1557 standards for TPU used in infusion, transfusion and injection equipment. They are free from added plasticizers, exhibit low extractables and are compatible with multiple sterilization.

Ideal for advanced healthcare solutions

Desmopan Rx grades are specifically developed for medical device components such as thin-walled flexible tubing, catheters, connectors, component housings, endoscopes, healthcare devices and wearables.

Tubing made with Desmopan Rx can be effectively used in a wide range of clinical applications, including surgical procedures, hemodialysis, drug delivery systems and wound care.

In addition, Desmopan Rx grades are well-suited for medical nonwoven applications due to their compatibility with melt-blown processes. Nonwovens made from these grades combine functional performance with compliance to medical waste regulations, making them ideal for surgical drapes, wound dressings, gowns, sterile packaging and protective equipment.

Key material benefits include:

• Biocompatible formulation suitable for direct patient contact applications

• High clarity for medical observation

• Excellent kink resistance to reduce tubing blockage risk

• Superior flexibility and dimensional stability

• Strong chemical resistance against oils, cleaning agents and disinfectants

• Outstanding abrasion resistance for demanding applications
