DuPont at Pharmapack 2012

20.01.2012
NEW grade of low friction, low wear DuPont™ Delrin® acetal resin extend the range of Special Control and Premium Control grades
The range of high performance polymers available from DuPont for use in medical devices, including the new DuPont™ Delrin® SC699 acetal resin forms the focal point of the company’s exhibit at Pharmapack 2012 in Paris (stand 561). Their use enables the design and manufacture of highly-accurate, reliable, durable and convenient products, as illustrated by the launch last year of the UnoPen™, a disposable, variable-dose injector pen for insulin and other therapies by the company Ypsomed AG (Burgdorf, Switzerland).

Ypsomed AG has specified the new, ultra low-friction Delrin® SC699 acetal resin for a key component of its UnoPen™. The DuPont material, which is supplied with extensive regulatory compliance for use in healthcare applications, is used to mould the pen's dose dial sleeve. Its low-friction behaviour facilitates use of the pen by diabetes patients who are required to administer daily injections of insulin either by themselves or with the help of a health care professional. Further attributes of this grade of Delrin® in the application include its mechanical properties and the compatibility of the material with laser marking when using a masterbatch.
The UnoPen™ from Ypsomed AG, a leading independent developer and manufacturer of injection systems, is a state-of-the-art disposable pen designed for the manual injection and delivery of insulin or other drugs from a pre-filled glass cartridge. A principal feature of the device is its ease-of-use based on a well-proven 'dial and inject' handling concept, in which the dose dial sleeve - the component moulded from Delrin® SC699 acetal resin and located between the housing and the piston rod - plays a key role. It is used by the patient to set the required dose of insulin to be injected and interacts mechanically with the piston rod to dispense the required dosage.

"The friction properties of Delrin® SC699 acetal resin used for the dose dial sleeve are fundamental to the pen's ease of use. If friction between the parts of the pen is kept to its minimum, then the patient will need a minimum of force to dose or inject the drug," explains Stefan Burren, manager product development at Ypsomed. "We tested many polymers that are currently available on the market for this component, but none fulfilled the requirements as well as the DuPont material."

Delrin® SC699 acetal resin has been modified for exceptional low friction performance and is suitable for high volume manufacture. It has been specifically developed for parts requiring high precision moulding in the healthcare industry and is supplied with the relevant regulatory compliance (FDA and EU food compliance, production according to GMP standards, testing against USP Class VI and ISO 10993–5 and -11). Further attributes of the new grade leading to its specification for the dose dial sleeve include its compatibility with laser marking, by use of an appropriate masterbatch, for indication of the dose settings. As with other grades from the Delrin® product family, the material also exhibits outstanding properties in terms of strength and stiffness, permitting the snap-fit assembly of the component, as well as ensuring reliable and durable mechanical performance in use.

Im Focus: AchemAsia 2019 will take place in Shanghai

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.

Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...

Im Focus: First real-time test of Li-Fi utilization for the industrial Internet of Things

The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.

Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.

Im Focus: Sharp images with flexible fibers

An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.

Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...

Im Focus: Water is not the same as water

Water molecules exist in two different forms with almost identical physical properties. For the first time, researchers have succeeded in separating the two forms to show that they can exhibit different chemical reactivities. These results were reported by researchers from the University of Basel and their colleagues in Hamburg in the scientific journal Nature Communications.

From a chemical perspective, water is a molecule in which a single oxygen atom is linked to two hydrogen atoms. It is less well known that water exists in two...
