High-flow polycarbonate goes to greater lengths

In recent years, healthcare products have become smaller and smaller as designers embrace the miniaturization trend. These devices, such as on-body drug delivery or monitoring applications, come with a new set of design criteria as they must be seamless, unobtrusive and lightweight to improve patient comfort and overall compliance. Smaller devices are also often used in surgery to advance patient recovery times. While these devices are used in a variety of applications, they all require one thing: materials with excellent flow properties to fill thin walls.
Spiral flow testing – increased flow length with Makrolon® Rx2235 polycarbonate
Spiral flow testing shown demonstrates the increased flow length that can be achieved when using Makrolon® Rx2235 polycarbonate.

We’re helping the healthcare industry go to greater lengths and meet the toughest design challenges with the launch of our new medical grade Makrolon® Rx2235 polycarbonate. Several medical applications can benefit from this high-flow material, including on-body devices, surgical instruments, pen injectors and IV components.

Featuring the inherent transparency of polycarbonate, Makrolon® Rx2235 polycarbonate sets a new benchmark for flow length to help OEMs fill very thin walls and accurately replicate intricate features with lower pressures. This material also plays an important role when cost and productivity mean multi-cavity tools.

Makrolon® Rx2235 polycarbonate meets the high standards of the healthcare industry, featuring biocompatibility according to ISO 10993-1 test requirements. It is also designed to be sterilized using gamma or e-Beam methods.

This high-flow material is a significant addition to our broad range of medical polycarbonates, which includes Makrolon® 2258 polycarbonate. This grade is suitable for ETO and steam sterilization, is biocompatible according to many ISO 10993-1 test requirements and offers low viscosity and easy release.

With our innovative and expanded polycarbonate portfolio, we’re giving our customers access to the advanced materials they need to design, develop and produce the next healthcare breakthrough.
