At MD&M West Conference and Exposition, held from 5 – 7 February 2019 in Anaheim, CA, USA, Covestro highlighted its broad portfolio of polycarbonate resins, blends and films, thermoplastic polyurethanes (TPU), TPU films and polyurethane-based adhesives and foams designed for the healthcare industry.
During the show, Covestro launched Makrolon Rx2235 polycarbonate, a new high-flow grade that can help manufacturers fill very thin walls and accurately replicate intricate features with lower pressures. This material is formulated for a variety of healthcare applications, such as on-body devices, surgical instruments, pen injectors and IV components.
The company also unveiled a connected drug delivery device prototype. This model incorporates various elements expected to be used in the future, such as clear and easy-to-understand language for self-administering patients, connectivity with the healthcare provider to ensure adherence to therapy recommendations and dosing, automatic detection of refill needs and more.
Additionally, Covestro highlighted the following applications utilising its materials and technologies:
- IV and surgical components: Due to their good balance of properties, including strength, durability and clarity, polycarbonate resins and blends are often utilised for a variety of surgical instruments, as well as syringes, catheters and other IV components.
- Medical device housings and drug delivery devices: Polycarbonate resins and blends from Covestro are used to form durable medical device housings that protect interior components. The company’s biocompatible polycarbonate materials also help portable drug delivery devices withstand continuous use and chemical interaction.
- Wound dressings and wound prevention: Polyurethane adhesive components from the Baymedix A range are characterised by good breathability and low trauma removal to wound care applications, while Baymedix FP polyurethane raw materials for foams possess good absorption and retention properties. Covestro also offers Platilon TPU films with a mat surface and other TPU materials for modern non-woven layers.
- Skin-friendly medical wearables: Wearable electronic patch devices benefit from breathable Platilon TPU films. Additionally, efficient production from roll to roll can be achieved using skin-friendly adhesive systems and thermo-formable foams based on Baymedix polyurethane raw materials. Covestro offers an overarching solution for wearable patch devices.
- Dental ligatures and medical tubing: Covestro TPU resins are used in several medical applications, including abrasion-resistant Texin RxS285 for dental ligatures. Texin RxT85A and Texin RxT90A can be used for various types of medical tubing due to their flexibility, and can help prevent tube blockages. These grades are also resistant to chemicals, lipids, cleaning agents and bacteria, and offer high clarity for enhanced visual observation.
Several end-use applications that utilise Covestro materials were on display, including drug delivery, surgical, IV and other innovative devices.
In addition, Covestro presented “TrendWatch Materials Matter for Connected Health,” a connected-device eBook developed in collaboration with the distribution business of PolyOne. The free and interactive eBook offers insights into the IoMT (Internet of Medical Things) landscape and implications for material selection and design.
