Serving polymer R&D

Many companies can, potentially, benefit from the creativity, expertise and facilities in polymer science available at the Polymer Centre at the University of Sheffield. FaraPack Polymers Ltd, a wholly-owned spin-out from Sheffield, offers clients the opportunity to access the University's network by means of short- to medium-term projects to solve immediate, trouble-shooting problems and to undertake proof-of-principle investigations to lower the risk profile of a long-term, strategic R&D investment with the University. FaraPack's capabilities encompass:

Research
Synthesis
Analysis

FaraPack's latest offering is in the area of synthesis scale-up using their 10 kg controlled lab reactor, Lara (TM). This facility enables clients to produce prototyping quantities of, for example, speciality coatings or composite matrices.

The Polymer Centre

The Polymer Centre at the University of Sheffield is a network of some 40 research groups active in all branches of polymer science and engineering, the UK’s largest single-university network in the field. The network includes world-leading academic experts in all aspects of polymer synthesis, processing and behaviour, from first-principles scientific understanding through to engineered applications in sectors like aerospace, coatings, electronics, energy, healthcare and home and personal care.

A business-facing Polymer Centre team provides a public face for the network, matching technical enquiries with the most appropriate academic resources, recommending relevant formats for interaction and assisting in project management as necessary. Where the most appropriate format for interaction is a short to medium term contract R&D project, we work with FaraPack Polymers, a spin-out of the University, to deliver programmes to client timescales and budgets. The Polymer Centre also delivers a range of training and conference events on behalf of our network, most significantly the Polymer IRC's short modular course in Polymer Science & Technology accredited by IOM3.

Sublime printing

Sheffield business Octi-Tech Ltd specialises in decorative systems, developing the technology and equipment for printing onto all sorts of products and surfaces. The company had developed a new system to decorate complex 3D surfaces – such as dimpled tiles or sculpted skirting boards – but were struggling to get the quality of image they needed.

Managing Director Paul Hirst explains: “The process prints the image onto a polymer film which then moulds to the surface of the product and transfers the image across. The films we had didn’t work well enough, but we were struggling to find anyone to help us develop a new one, until we came across the Polymer Centre at the University of Sheffield.”

The Polymer Centre directed them to spin-out company, FaraPack Polymers Ltd, which was set up to help companies needing research expertise on short-term projects, such as engineering problems, technology issues or new product development. They also helped the company gain a Yorkshire Forward Innovation Voucher, which covered the costs of the initial research.

FaraPack’s specialism is developing new and bespoke polymers which made them the ideal partner for Octi-Tech, as Operations Manager at FaraPack, Chris Saywell explains: “Transferring the image from the film to the object involved interactions between nano-sized particles in the film coating and the inks. We worked on a new coating for the film to increase the dye transfer to as close to 100 percent as possible.”

The FaraPack team tested options for different coatings in the lab until a prototype was developed. Then FaraPack sourced a company able to produce the film to full scale. The whole process took three months and the result was a film which enables high quality image transfer, allowing Octi-Tech to launch their new system. Paul Hirst doesn’t claim to understand the science, but is very glad to have found the solution.

“We didn’t think of it as a nanotechnology problem – just as polymer film that needed a new coating on it,” he said. “ We’re now working with FaraPack on other projects as well, and the collaboration looks set to continue.”

Natural antibiotics

Nature’s Laboratory, a Whitby-based business, has developed a water soluble form of propolis, a resin collected by bees and used by them as an immune defence mechanism. This has numerous therapeutic effects, including antimicrobial, immunomodulatory and anti cancer and has the potential to greatly improve human health. One of the barriers to the commercial success of this product however was its strong, pungent odour.

In a project funded by the Molecular Engineering Translational Research Centre (METRC), researchers at the University of Bradford's Institute for Pharmaceutical Innovation worked with Nature’s Laboratory scientists to create a process to deodorise the product. Company founder James Fearnley, who set up the state-of-the-art laboratory, said it was a big breakthrough. “We have been involved in this research for 20 years and have just released a paper about how propolis can be used to help fight MRSA,” he said. “This award is very exciting as propolis is very pungent smelling and what we have been doing is removing that smell without reducing its effects. Our product will now be sent to a customer in Korea to be used over there and the implications are massive.”

Nature’s Laboratory and the Institute of Pharmaceutical Innovation at Bradford have been nominated for a “Partners in Innovation” award at the Yorkshire Forward Innovator/10 Awards Ceremony.

Soft nano for roofing repair

Euro Polymers (GB) Ltd is a leading provider of polymer coatings used in waterproofing, primarily for building protection. For the last three years they have been working with scientists at the Sheffield Polymer Centre, looking to improve their existing products with new formulations based on the exploitation of soft nanotechnology. The new Eurotec polymer system developed as a consequence of this collaboration, is able to penetrate the surface of bitumen or asphalt substrates, then self-assemble into interlocking structures like nanometre-scale Velcro. This gives much better adhesion as the products bond at a molecular level.This gives a significant advantage over the market leading systems, which simply sit on top of the structure. Eurotec becomes one with substrate, giving almost 5 fold stronger bond to prevent wind uplift.

A further advantage is that the new material formulation makes extensive use of recycled materials, giving the new product strong green credentials.

Intelligent buildings

Intelligent building

Designing ‘intelligent’ buildings to resist earthquakes could potentially save thousands of lives every year. The University of Leeds has been collaborating on a £9.5m EU funded project with a number of partners, including ‘Instrumentel’ a Yorkshire based SME, to test ways of building safer housing in earthquake zones. With self-healing polymers and wireless, battery-less sensors to provide early warning, incorporated into the walls, the eventual prototype will be built on a Greek mountainside in Amfilochia.

Safer root canal treatments

Seal-smart packs for safer root-canal dentistry

There are over 100 million root canal treatments performed worldwide in the course of a year & these treatments are the major cause of complaints against dental practices with a 30% failure rate for traditional treatments. Bradford University worked with DRFP Ltd to develop nano-materials and a manufacturing route for a new treatment product which significantly reduces the requirement for re-treatment or extraction.

This process won 'Best Technology Application' at the Plastics Industry Awards 2008.

PVD drill coatings

PVD Drill Coatings

Sheffield Hallam University worked with 'Hydra Clarkson International Ltd' investigating ways to improve the life of cutting tools, sold for use in the dry-drilling and milling of aerospace and automotive alloys.

A range of new nanoscale PVD coatings were developed which combined high
hardness, low friction and chemical inertness.

Tests have shown that coated tools had a significantly improved life, producing 130 holes compared to one to two holes with uncoated tools, and out-performed competing coatings by a factor of three.
