For more than 30 years, Queen’s University, Belfast (QUB) has been internationally renowned for its innovative research into the rotational moulding of plastics. Most recently QUB has finalised a License Agreement with Maus GmbH, Germany for a ‘Rotocooler’ internal water spray cooling device. The Rotocooler® Device has been in development in various guises at QUB for more than 10 years and is a new technology developed and aimed specifically at speeding up the manufacturing times of rotationally moulded products such as water and oil storage tanks. For too long, critics of the rotational moulding process point to its long cycle times required to produce a plastic part, as opposed to other processes such as injection moulding or blow moulding. For too long, the rotational moulding process has suffered from long production times due to the long cooling times.

Welcome to this May 2014 edition of the PPRC Newsletter which provides information on support for Technology Transfer and some Projects in which the Centre is involved.
PPRC Visit to ISPA
PPRC Process Engineers Dr Paul Hanna and Mr Mark Billham were invited by the Higher Institute of Plastics, Alencon (ISPA) in France to lecture on the current state of the art in Rotational Moulding and Multi-layer Extrusion respectively. The lectures were attended by over fifty Polymer Engineering Bachelors/Masters degree students as well as ISPA staff. Internationally leading research conducted at the PPRC, including its impact on wider society, was also showcased during the presentations.
Following tours of ISPAs facilities, discussions were held on current and potential areas for research collaboration, during which ISPA were keen to establish a joint PhD programme of study.

Joe Molloy, Technical Director with IPC polymers, Mark Billham, Research Fellow at the Polymer Precision Research Centre at Queen's University, Belfast and Dr Marion McAfee, of the Department of Mechanical and Electronic Engineering, IT Sligo, demonstrate an artificial knee joint at the launch the €1million Bio-PolyTec EU FP7 research project. The project aims to progress the commercial availability of bioresorbable and drug-eluting medical implants.
Researchers at Queen’s are collaborating on a €1 million EU funded project to pave the way for people to receive better and cheaper medical implants in a more timely manner.
The Queen’s team are based within the Polymer Processing Research Centre (PPRC) located in the School of Mechanical and Aerospace Engineering. The two-year initiative is funded by the European Union’s Seventh Framework Programme (EU FP7) for Research and Technological Development. The project, termed ‘Bio-PolyTec’, targets greater use of bioresorbable polymer materials rather than metals in implants, thereby bringing important benefits for patients and manufacturers.
Professor Fraser Buchanan, who leads the Queen’s team, said: “Bioresorbable polymers are set to play a major role in the future development of implantable medical devices. They are becoming established in a number of key applications ranging from orthopaedic to cardiovascular. Bioresorbable polymers have key advantages over traditional metal implants. They naturally breakdown into non-toxic by-products and are gradually replaced by the patient’s own tissue, leading to improved patient recovery.”
The materials are seeing increasing application in treatment of trauma and sports injuries, including internal bone fixation devices (screws, plates and pins) and reattachment of ruptured ligaments (suture anchors). Furthermore an innovative new product called ‘RegJoint’ is now produced by project partner Scaffdex, for the treatment of osteo and rheumatoid arthritis in the small joints of the hand and foot. Bioresorbable polymers can also incorporate drugs and bioactive additives, which are slowly released as they degrade, broadening applications to pharmaceutical therapies.
Dr Nicholas Dunne, Director of Queen’s PPRC, says that one of main obstacle to wider use of bioresorbable implants for medical applications has been challenges in their manufacture. With the project consortium now having access to the world-class facilities available within the PPRC there is an opportunity for the Bio-PolyTec team to develop novel monitoring and control techniques which will speed up processing methods and significantly reduce scrap-rate of the costly material.
Mark Billham, PPRC Research Fellow on this project, has extensive industrial and collaborative research experience in many areas of polymer extrusion and polymer materials, and will be working in close cooperation with all industrial and academic project partners.
The project partners are from the UK, Finland, Germany and Ireland. They include academics at two universities, including Sligo Institute of Technology, who coordinate the project, and Tampere University, who originally founded the use of bioresorbable implants. Industrialists include biomaterial processors, device manufacturers and specialists in sensor technology.
The other partners in the initiative are:
- IPC Polymers Ltd (Ireland), a manufacturer of polymer compounds for the medical industry
- Scaffdex Oy (Finland), which makes bioresorbable tissue scaffolds for treatment of arthritic joints
- Fos-Messtechnik GmbH (Germany), whichmanufacture sensors for the process industry, particularly optic sensors and related technologies
- Plasma-Biotal Ltd (UK), who provide bio-active particles for orthopaedic implants.
- Corbion Purac (Netherlands), a manufacturer of bioresorbable polymer

Welcome to this September 2013 edition of the PPRC Newsletter which features some of the EU funded projects in which the Centre has been involved.
Building on last year's success in gaining a Bronze award, PPRC earned a Silver Award in the national environmental accreditation and award scheme run by the National Union of Students.
Working across UK students’ unions, universities and colleges and community organisations, Green Impact supports departments to make simple, tangible and powerful changes in behaviour and policy. From recycling, to investing in more efficient equipment, to encouraging biodiversity, or Fairtrade, the various criteria cover a broad range of issues under the sustainability umbrella.

Guest Lecture: The Advanced Materials and Processing Research Cluster look forward to a visit from Prof. Graham Cross from the CRANN Institute, Trinity College Dublin, on 28th February 2013. During the visit, Prof. Cross will tour the extensive processing and material characterisation facilities in PPRC and give a lecture on the subject of 'Polymer Deformation During Nanostructure Fabrication by Mechanical Processing' to staff and students in the School of Mechanical & Aerospace Engineering.

Dr Mark McCourt Speaking at the Design and Innovation in Rotational Moulding Seminar
The Rotational Moulding Group of the British Plastics Federation hosted its annual ‘Design and Innovation in Rotational Moulding’ Seminar on the afternoon of the 30th May 2012 at the London Excel Exhibition Centre. The seminar presented a case for the versatile nature of the rotational moulding process to manufacturers, designers and suppliers.
The medium was a series of case studies helping to educate designers on what can be achieved through the rotational moulding process. These examined a variety of products including a portable hand wash system and a road traffic safety sign.
The Group was also joined by Dr. Mark McCourt of Queens University Belfast who gave a detailed overview of the industry, Dr Nick Henwood of Rotomotive Limited who spoke about the challenges and opportunities that can be achieved through different rotational moulding materials and Hans Petersen of Creactive Design who presented a case study from a designer’s perspective.
The Seminar took place at this year’s PDM exhibition which is the only dedicated design and moulding event in the UK and it is the place for plastics and design professionals to network, learn and be inspired.
Karen Drinkwater, Chair of the BPF Rotational Moulders Group said 'We have been delighted with the response to the rotational moulding seminar at PDM. The wide range of presentations given by our group members really engaged the audience and raised the profile of the rotational moulding sector with those designers present. Increasing the understanding of the process can only be beneficial to the growth of the industry as a whole.'
Jonathan Bloom, Senior Executive at the BPF stated on the day ’there is a host of information on the rotational moulding process and the Group members that can be found on the Group website http://bit.ly/Lpras5
