Covestro is now exhibiting at the Medical Taiwan Virtual Show.

New polycarbonates meet demands for drug delivery and surgical devices

  •  We  have expanded our medical-grade product portfolio with low-friction and glass-filled materials

To provide patients and medical professionals with a smooth drug delivery experience and high-strength materials required for surgical devices, Covestro, a high-tech material manufacturer with more than 50 years of experience in the healthcare industry, continues to expand its medical-grade product portfolio with Makrolon®. The company will showcase the new low-friction and glass-filled polycarbonates at the Medical Taiwan Virtual Show and at the MCMEX Taiwan Virtual Show. The MCMEX Virtual Show booth is open from now until 31st October. During the exhibition, you can login to browse the exhibits via mobile phone or computer. Covestro also caters to the needs of the healthcare industry in Taiwan; the company will display high-performance polycarbonates and polymers that can be used to manufacture chemically resistant intravenous infusion accessories, smart-wear products and high-impact goggles.


Smooth delivery with low-friction polycarbonates

Patients are increasingly using autoinjectors and injection pens to self-administer therapeutics from the comfort of their own homes or when on the go. These devices are expected to operate consistently every time and utilize low-friction components to ensure injections are reliable and smooth.


To meet challenging low-friction requirements, Covestro is launching three new medical-grade polycarbonates: Makrolon® M204 LF, Makrolon® M402 LF and Makrolon® M404 LF. Featuring reduced coefficients of friction, these grades deliver the excellent dimensional and mechanical properties of polycarbonate while eliminating the need for external lubricants.

The new low-friction Makrolon® polycarbonates offer the following benefits to drug delivery devices:

  • Lower deployment forces
  • Durability and biocompatibility in accordance with ISO 10993-1
  • Sterilizable through various methods such as autoclave, ethylene oxide and radiation (e-Beam, gamma)

“We built on the superior performance of polycarbonates to formulate low-friction grades that offer consistency and versatility which, in turn, help OEMs design devices that address emerging drug delivery trends,” said Doug Hamilton, the Global Healthcare Marketing Leader of Covestro LLC.

Superior strength with glass-filled polycarbonates

Covestro has also developed new glass-filled polycarbonates for surgical and drug delivery applications that demand stiffness and strength. They can be used for load-bearing internal components in drug delivery devices and for handles in minimally invasive or laparoscopic surgical tools.


These grades are divided into two series with varying levels of reinforcement. The high-performance series includes the Makrolon® M810 GF, Makrolon® M820 GF and Makrolon® M830 GF polycarbonates. In the high-flow series, the Makrolon® M410 GF, Makrolon® M420 GF and Makrolon® M430 GF polycarbonates are used to create larger or thinner parts with improved productivity.

Additional advantages of Makrolon® GF polycarbonates include:

  • Biocompatibility in accordance with ISO 10993-1 for products that last less than 30 days
  • Superior rigidity and strength
  • A high-gloss surface is achievable with rapid heat- cycle molding
  • Higher tensile modulus and tensile strength, and improved dimensional stability under stress when compared to unfilled polycarbonates


“Our expanded materials offering gives healthcare OEMs access to a wide range of glass-filled polycarbonate products that deliver performance tailored to fit their applications,” said Mr. Hamilton.
