Consumer Electronics

Consumer Electronics Kuender & Co., Ltd. has been established since 1990, with a vision is to offer customers reasonable price together with the best service and also creates win-win business and long- term relationship with customers. In addition to its Taipei headquarter (Taiwan), Kuender also have manufacture plants both in Taoyuan, Taiwan and Wujang, China. Kuender group is a professional OEM/ODM manufacturer to provide total solution for brand customers in various products, say air cleaner, consumer electronics, etc. From tooling design and mold injection to assembly of complete unit, Kuender offers customers tremendous advantages on cost, speed and service. As a good citizen of the world’s responsibility, Kuender decided to become a green partner to all his customers by providing a range of greener choices. www.kuender.com SUPLA has dedicated itself in producing high performance PLA since 2007. SUPLA’s achievements in PLA blends of high heat resistance and flame retardant have been reported in bioplastics MAGAZINE in the issues of 01/2010 and 05/2010, respectively. SUPLA has its manufacture plants both in Taiwan and Suqian, China. SUPLA recently announced it is constructing a 10,000 tonnes/a PLA polymerization plant in China that will be become operational in 2014. www.supla-bioplastics.cn, www.supla.com.tw in Raw Materials, Machinery & Products Free of Charge from the Industrial Sector and the Plastics Markets for Plastics. for Plastics & Additives, Machinery & Equipment, Subcontractors and Services. All-In-One (AIO) PC with 21.5” touch screen, and an naked-eye 3D media player, by using Supla’s new grade of durable PLA blend (Supla 155) on their housings. This is the first time that PLA has proven itself ready for a mass production line of consumer electronics. And it implies that PLA can replace oil-based plastics such as HIPS and ABS, and alleviate our dependency on fossil fuels. The AIO PC is the latest version of personal computer combining PC and the monitor. Kuender’s AIO PC has a 21.5” touch screen, which makes the keyboard an optional component. Since this All-In- One PC includes all the devices under one housing, the structure and functional requirements for the housing are much more demanding. The front and back covers have more demanding on the physical properties of the material and the stability of dimensions. Facing this challenge, Supla started by choosing PLLA and PDLA homopolymers from Corbion Purac’s lactide monomers, which are GMO free, as the base. PLLA and PDLA homopolymers have better potential for further blending and balancing other properties including heat resistance, flame retardant, toughness and dimensional stability while keeping the injection molding cycle time as short as possible. A new mold was designed for the production of this AIO PC accordingly. Under a close partnership with Supla, Kuender was able to master and optimize the injection molding process of these PLA homopolymer blends. This includes for example the proper mold temperature, the arrangement of heating sources in the mold, the flow pattern of the polymer melt, and the control of dimensional stability. The resulting new front and back covers of the AIO PC pass the test standards originally developed for ABS covers. For this AIO PC’s, the retail price will be around 0 USD. The change of material from ABS to PLA will increase the cost less than 2%. As an OEM/ODM professional, Kuender launches this product to provide brand customers a greener, biobased material for the housing in addition to Kuender’s green display technology, OGS (the OGS stands for One Glass Solution for touch panel) with an excellent cost/performance ratio. for Specialists and Executive Staff in the Plastics Industry 40 bioplastics MAGAZINE [06/13] Vol. 8

Consumer Electronics With 50 million tonnes of waste produced worldwide every year, electronics (smartphones, tablets, computers, etc.) are now a serious problem for the environment. To reduce the impact of the so called e- waste, a new contribution has arrived in the form of bioplastics designed by bio-on, as stated in a recent press release by the Bologna, Italy based Intellectual Property Company. Their product is a PHA made from beet and cane sugar (in Italy in collaboration with Co.Pro.B.), using a natural production process without the use of organic chemical solvents. It is 100% naturally biodegradable in water and soil and can be used as a substrate for electrical circuits. When combined with suitable nanofillers, it can act as an electricity conductor, with extraordinary, as yet unexplored potential. PHA for electronic applications “In this way it’s possible to build electronic devices with a reduced environmental impact”, Marco Astorri, CEO and co-founder of bio-on, explained during Maker Faire 2103 in Rome, Italy. “But the use of bioplastics will not be restricted to smartphones and tablets. We can extend it to highly advanced technological sectors, thanks to the multiple features of our bioplastics, their outstanding technical performance and excellent biocompatibility. In the future this will also enable us to develop sensors and electromedical equipment for health care,” added Astorri. The possibility of incorporating electrical and electronic circuits in plastic substrates, to obtain flexible, lightweight and easily integrated electronics, has been the subject of investigation by a team of Italian researchers from the Departments of Engineering of the Universities of Modena-Reggio Emilia and Perugia. They integrated carbon nanoparticles like nanotubes and graphene into bioplastics produced by bio-on, making them suitable for the development of sustainable electronics. The preliminary results of this research were presented in Rome during BIOPOL 2013, the International Conference on Biodegradable and Biobased Polymers. “This type of plastic reduces the environmental impact of the device”, according to Paola Fabbri, a researcher at the Enzo Ferrari Department of Engineering of the University of Modena and Reggio Emilia, “making recovery easier and cheaper.” “As much of the plastics currently used in electronics can now be replaced by biopolymers such as bio-on’s”, the researchers say, “many businesses can already benefit by reducing the impact of the life cycle analysis (LCA) of electronic devices, as recommended by the European legislation”. Bio-on is an Italian company that develops new materials in the modern biotechnologies sector and this recognition completes the industrial research project, started in 2007, aimed at producing naturally biodegradable plastic, starting from sugar beets and, as of today, also from sugar cane. The idea is especially innovative since, for the first time in the world, PHA (polyhydroxyalkanoate polyhydroxyalkanoate) was obtained from molasses or intermediate sugar cane juices or from its by-products and not from oils or cereal starches like many other biopolymers on the market today. MINERV ® PHA bioplastics are thus made from waste materials and not from products intended for food production. This, combined with their complete biodegradability in water, is the big environmental advantage of the bioplastics developed by Bio on. www.bio-on.it bioplastics MAGAZINE [06/13] Vol. 8 41
