New polymers contribute to the fire in the hottest

From the touch screen called "artificial muscle", to all kinds of flame-retardant plastics and elastomers to ensure the safety of electronic products, to the intervention of nanotechnology, it can be said that polymers have not only become an important material of consumer electronic products, but also played an irreplaceable role in promoting their rapid upgrading

electroactive polymer: new experience of iPod touch screen and game equipment

traditional keys and buttons gradually fade out of the market and are replaced by various types of touch screens. However, in the process of using the touch screen, users are often uncertain whether the required commands are executed. And many users cannot adapt to this complex navigation menu. At present, the existing solutions in the market have not yet been able to meet the requirements of synchronous feedback of visual, auditory and tactile signals. The electroactive polymer from Bayer materials technology (BMS) can quickly and accurately provide tactile feedback information. Due to its special properties, it will deform when applying voltage, so it is also called "artificial muscle"

Ms. ELISA Picasso, functional film business development manager of Bayer materials technology, explained: "mobile electronic devices often use this kind of polymer, so that users can get feedback directly through the touch screen. Once the touch screen is activated, the polymer can make fine adjustments and execute different task commands." This is different from the existing mechanical vibration solution technology on the market, so it enriches the selection of intelligent, game controller and touch panel materials

Bayer Materials Technology Co., Ltd. and its acquired company, artistic muscle (AMI), participated in the European leading mobile communication trade show GSMA mobile communication world conference held in Barcelona, Spain, in February this year for the first time, and demonstrated this innovative solution for intelligence and mobility made of electroactive polymers and polycarbonate films. The current main project is the promotion of bayfolreflex driver. When the mobile touch screen and integrated antenna are activated, the device can provide corresponding feedback. In addition to bayfol reflex technology, AMI will launch the operational version of mophie pulse. Recently, Bayer materials technology signed a license agreement with immersion Corporation to provide customers with various tactile enjoyment

the first commercial product that combines bayfolreflex is the popular mophiepulse press feedback game on ipodtouch. The synchronous and accurate feedback of the product enhances the interactivity of ipodtouch games and is compatible with most existing ipodtouch games

safety, regeneration - green electricity and other sub core demands put forward higher requirements

flame retardant has become one of the manufacturing requirements of more and more electrical/electronic products, and many manufacturers have also begun to take the initiative to use such products. Advanced high-performance engineering plastics can just meet this demand, because they have the advantages of halogen-free, fire-resistant, flame retardant and so on

tecona, the high-performance engineering plastics business of Celanese, has provided a series of plastic products suitable for the field of electronic appliances, and recently expanded this product line again. DuPont's liquid crystal polymer lcpzonite has just joined the product series of tecona LCP. Zenite is a liquid crystal polymer with flame retardancy. It has very good heat resistance, especially suitable for the surface installation of electronic and electrical components (SMT). At the same time, it has high resistance to lead-free solder, which is obviously superior to ceramics, thermosetting plastics and other LCP materials. It can achieve better performance, faster manufacturing speed and lower system cost. Zenite is used in many applications, such as switches, connectors and memory sockets for game consoles, laptops, televisions, and other electrical and electronic devices

many consumer electronics manufacturers have stopped using halogen flame retardant plastics to improve environmental protection

while considering flame retardance, color is also an important design element and safety performance. More and more enterprises begin to choose halogen-free flame retardant plastic without red phosphorus, because its inherent dark color can prevent the corresponding component color from shining when it reaches high tonnage. Red phosphorus can also cause corrosion when it comes into contact with metals in warm or humid environments. Polyamide 66 Durethan dpakv30 fn00 of LANXESS, a special chemicals group, has achieved great success in the Asian market as a flame retardant component material for consumer electronics. This polyamide additive is not only flame retardant but also free of red phosphorus

"our materials have reached an excellent level in flame retardant testing. We have constantly improved the inspection and testing support service system, and have a wide injection molding processing window, which is very suitable for plug connectors, coil racks, small USB plugs and other thin-walled parts." Milan vignjevic, head of Asia Pacific of Langsheng semi crystalline products business department, explained. According to the UL94 standard of Underwriters Laboratories (UL), a US product safety testing and certification agency, Durethan dpakv30 fn00 has high flame retardancy. In resistance wire ignition (HWI) and high amperage arc ignition (HAI) tests, the material was listed in the best performance level category (plc0), even when the thickness was 0.4 mm. This makes it an excellent insulating material conforming to ul508 standard. Polyamide 66 also has very high electrical performance and is listed in the best category (plc0) on UL yellow card. This performance can greatly reduce the risk of short circuit and equipment failure caused by leakage in applications

the new polyamide 66 also has a wide injection processing window. This material can easily handle film wall thickness below 1mm, for example, in plug joints. In many applications, it is used to replace flame retardant PBT, polyamide 46 and poly (phthalamide)

elastomers, which have the advantages of both plastic and rubber, are also increasingly used in the field of electronic products, and their safety is also the focus of electronic manufacturers. PolyOne Gillis thermoplastic elastomer department, the world's leading manufacturer of high-performance customized thermoplastic elastomers, exhibited three new grades of on flex hffr300 halogen-free flame retardant thermoplastic elastomers at Chinaplas 2011. These new products help users enter the application fields that need to achieve flame retardant performance and excellent appearance without using halogens and phthalates, such as replacing traditional flexible wire materials

onflexhffr 300 product series can provide excellent processability, superior performance and beautiful appearance, and meet the European Union and VDE standards, UL's strict regulations on the flame retardancy of flexible wires and other international standards. On flex HFFR and on flex are injection molding grade materials used to manufacture connectors, plugs, gaskets, seals, and sheath stress protection. On flex HFFR is an extrusion grade material, which is mainly used in ribbon cables, sheaths and insulation layers that require soft covers and flexibility. This material can meet ul1581vw-1 grade. The above three product grades can meet the requirements of Tosca, reach and RoHS

an important feature of consumer electronic products is the continuous innovation, which also urges many consumers to replace consumer electronic products regularly and produce a large amount of electronic waste. On the other hand, subject to various regulations, such as the regulation of the American "environmental impact assessment tool for electronic products (EPEAT)" and ecological labels, consumer electronic products also require more and more environmentally friendly materials. The emerge 7800 and 7880pc/abs resins developed and designed by Styron, the world's leading raw material manufacturer, are specially designed for consumer electronics applications. They contain% of PCR (recycled material) resins while maintaining the necessary strength. Both products are certified by third parties including TV

in addition, reducing the overall production cost by simplifying the production process is also an important aspect of achieving sustainable development. For example, emerger resin series, another resin of Styron, not only has the characteristics of soft touch and good scratch resistance, which is suitable for smart and tablet computers, but also provides polishing effect (eliminating welding lines, avoiding residues and less ripple), so that the products do not need to be sprayed

this "spray free" scheme not only helps to reduce production costs, but also avoids the use of organic solvents in the production process. It is reported that emergere high-performance engineering resin has been highly praised by industrial designers of internationally renowned brands

nanotechnology intervene to improve cleanliness and prevent scratches

PolyOne launched a new stat technt carbon nanotechnology polymer product series, including a variety of product solutions based on POM (polyformaldehyde), Peek (polyether ether ketone), PC (polycarbonate) and other thermoplastic engineering plastics. The carbon nanotechnology can provide better electrostatic protection effect. It has the advantages of more uniform surface conductivity, higher product purity and cleanliness. At the same time, it also maintains all the mechanical properties required for applications such as electronic storage devices, integrated circuit packaging and semiconductor devices

materials containing conductive fillers help to improve the conductivity of plastics, thereby preventing the accumulation of electrostatic charges. However, the traditional conductivity avoids the damage of the instrument due to short circuit. The addition of filler may have a negative impact on the physical properties of the material. Because stat technt adopts carbon nanotube technology, it does not need to use too many conductive fillers. Therefore, the influence of this additive on strength, shrinkage, warpage and fluidity can be minimized. This means that such materials are easier to process than traditional fillers using carbon black or carbon fiber

stat technt can effectively improve conductivity and minimize the "hot zone" caused by uneven distribution of conductive fillers. In addition, this new formula has a low particle formation index, so as to ensure that the material has a very high purity and avoid possible pollution caused by traditional fillers. With these advantages, semiconductor and hard disk drive manufacturers can ensure that their products meet high cleanliness requirements and prevent the occurrence of disc scratches and other phenomena. If traditional conductive fibers are used, the surface of the wafer is more likely to be scratched

stat technt nano material products have been fully listed in the Asian market. PolyOne plans to promote the new series to the global market. With the continuous expansion of product portfolio, this technology will be applied to more basic resin products to meet customers' different use requirements

the transformation from single black to customized color

saber basic innovative plastic announced the launch of the first colored LNP thermocomp thermoplastic composite at Chinaplas 2011. This material, which can be used in laser direct molding (LDS) technology, can save space and reduce the weight of mobile devices

lds technology is a complex process that integrates electronic and mechanical functions into a single module such as notebook antenna, which can further realize the miniaturization of notebook and tablet computers, but it still has certain limitations in terms of appearance aesthetics. Previously, only black plastic materials could be used in this manufacturing process, and designers usually can only enclose LDS components in the equipment

saber basic innovative plastics has cooperated with LPKF laser Electronics Co., Ltd., a leader in LDS technology, for many years, and has taken the lead in launching black material technology solutions. Nils Heininger, vice president of LPKF's cutting and forming laser business department, said, "it can integrate antennas, sensors and other functions into the equipment shell, which helps to achieve the integration of components and design thinner and smaller products. The development of materials from basic black to custom color is a great progress."
