news Petlon chews over gum recycling
UK-based technical com- pounder Petlon Polymers Limited has signed a joint development agreement with Gumdrop to develop polymer compounds made using recycled waste chewing gum. Gumdrop was founded in
the UK in 2009 to provide systems for collection and recycling of waste chewing
gum. “We’re the first company in the world to recycle and process chewing gum into a range of new compounds that can be used in the rubber and plastics industry,” says Gumdrop Managing Director Anna Bullus. “This exciting new develop- ment utilising Pelton’s extensive polymer knowledge
is designed to take the compounds further up the polymer value chain,” she said. Petlon said it will use its
formulation, laboratory and manufacturing expertise to incorporate the recovered chewing gum compounds for applications ranging from packaging to consumer goods. ❙

8 news in brief Nanomaster project closes
Spanish plastics institute AIMPLAS announced the completion of the EU-funded Nanomaster graphene research project, claiming real progress towards commer- cialisation of the nano-materi- als in multiple sectors. Nanomaster was funded by Framework
the EU’s 7th
Programme and involved 14 industrial participants,
including Lego, Philips, Rochling and Imerys. According to AIMPLAS, the
project “has developed graphene concentrates offering the chance of using these particles in the conven- tional plastics processing and additive manufacturing”. The materials investigated
in the programme included nanographite and expanded
graphite masterbatches. AIMPLAS’s role was to develop optimised graphene concen- trates for use in injection moulding and extrusion processing and for additive manufacturing (both in powder and rod forms). One key finding of the
Nanomaster work, the association noted, is that the number of layers, particle diameter, and the amount of oxygen present in the particle are the most important factors when synthesising graphene by graphite exfoliation. It also said graphene generally was found to become more effective as the number of layers is reduced. ❙

Entek launches screw software
Twin screw extruder maker Entek has intro- duced a new software program that it claims “will enable customers to quickly and easily design screw and barrel layouts for their specific applications”. Key built in features of the software include:
drag and drop functionality on all components that need to be specified, such as barrel
