In line with market trends in the materials and equipment the double "catalyst", the plastic in the field of electrical and electronic applications will be more extensive, in-depth, future worth looking forward to this market.
Innovative concept of the future display
With the advent of new technology and image quality, more and more families began to buy flat screen TVs. Compared with traditional TV, such TV with light weight, space saving, energy saving, powerful and so on.
LCD TV as a cross-section of ultra-pure PMMA polymethyl methacrylate (PMMA), the LCD TV manufacturing plays a key role. Evonik Director MichaelZietek optical surfaces, said: "plexiglass because it also has optical properties, make it possible to optimize the display lighting." Plexiglass as optical materials, plays a central role in this, can ensure the best uniformity of brightness and light distribution. Combination of light must be evenly distributed throughout the display surface shall not have any wear and tear, long-distance transmission time is no exception. Zietek added: "Our material has excellent optical purity and transparency, especially for this purpose. At present, this material has been successfully applied to the navigation device displays, mobile displays, LCD flat screen display and TV display and other fields. "
The material structure is very complicated. However, by continuous melting of the material layers can be built on the flat screen TV display. Even for light transmission for display purposes, play a key role in plexiglass. In the ultra-flat form, the polymer material is especially suitable for that purpose. To make liquid crystal displays for TVs, all aspects of development agencies have to give full play to the potential of existing innovations. MichaelZietek said: "When viewers watch television relatively distant from the big screen. Therefore, the need for more light to get the required brightness."
The edge of a small light used to monitor the system does not apply to the big screen because of the brightness can not produce the necessary can not form a uniform lighting. Therefore, for more than 15-inch screen size, you need to thin neon tubes or LEDs directly (LED) placed on display later. Light scattering in different materials and light guide material composition of the material layer to ensure uniform illumination. Currently, research is continuing, the target is to produce in a single plane of light scattering within the disc. This special role can be further improved light output.
Plexiglass just icing on the cake for TV display, but also to mobile phones and other products look more beautiful. Evonik has developed a low cost for this solution. Fashion panel is the adoption of mobile phone coated with acrylic coating, optimized for high-level of professional film. The film is placed in injection mold, molding compounds used in the mold by injection molding. This process does not require subsequent processing, especially with the economic benefits. For product design, the design flexibility provided by this technology is the key to market success. For example, the phone can be in the light shining in dark disco. This effect can be embedded in the acrylic phosphorescent dye achieved.
ValoxiQ poly butylene terephthalate (PBT) resin flame retardant through the use of proprietary technology to meet the requirements of halogen-free parts. In addition, some of their waste after use recycled plastic (including PET bottles), and thus help to reduce fossil fuel use. Other plastics on the market than they are in the plastic manufacturing process can be reduced by 50% or more of the energy and carbon dioxide emissions. In addition to helping electronics manufacturers comply with environmental regulations (such as the EU Waste Electrical and Electronic Equipment (WEEE) Directive) outside, ValoxiQ resin can also meet the Electronic Product Environmental Assessment Tool (EPEAT) to the material selection requirements of Africa, to help manufacturers are certified.
SABIC Innovative Plastics Electronics Global Marketing Director said Hiroshi Yoshida: "ValoxiQ resin for green electronic products not only provide good development possibilities, and has long been used as a computer cooling fan of the commercial production. In addition, we are expanding iQ Series product range to cover other environmental materials, such as amorphous polycarbonate and semi-crystalline PBT resin mixture XenoyiQ, the material shell and the external panel is the better choice. "
