Engineering plastics innovation continues to open up application space

the soaring oil price has become the most concerned problem in the world, which has led to the rising prices of energy and resources. For a period of time, the price increase has become the highest release density among raw material suppliers. Nevertheless, the innovative application of various excellent engineering plastics to replace metal, glass and other components is still the focus of public attention. In recent years, on the one hand, the technological innovation of engineering plastics has attracted more and more attention in the innovative application fields such as solar energy and laser printing. On the other hand, a variety of new technologies have also emerged in the traditional automotive, medical, electronic and electrical fields

responding to the changing needs of the new energy era

in recent years, in Asia, Europe and other regions, the demand for solar energy is increasing day by day. According to the statistics of Solarbuzz, an international solar energy research and consulting company, the global photovoltaic industry earned about US $17billion in 2007. Leading suppliers in the plastics industry have long been optimistic about this market and have actively developed a variety of different products to be used in this industry

DuPont has more than 20 years of experience in photovoltaic material development, application, professional manufacturing and global marketing, and has developed a variety of DuPont innovative material combinations for solar modules

key materials developed by DuPont for solar photovoltaic components (PV), including films, plates, resins and conductive pastes. For example, DuPont Tedlar PVF film has been an indispensable component of backing materials for 20 years. Tedlar has become an industry standard due to its excellent ductility, weather resistance, UV resistance, moisture resistance and reliable life cycle. In order to meet the increasing demand of the industry, DuPont has also developed a new generation of Tedlar film products for solar modules - Tedlar 2100 Series, to provide greater dimensional stability, not easy to deform, tear resistance, wear resistance and high reflection coefficient of 180 °, and improve the overall power generation efficiency. DuPont butacite intermediate film has the following characteristics: toughness, as a thermoplastic glass interlayer, can be used to package solar cells, and has excellent glass adhesion and optical properties; Laminated glass complies with the national safety standards; With high tear strength and rigidity, it is most suitable for installation in the design of glass modules with strict requirements for impact resistance and structural performance. The special design adopted by DuPont sentryglass plus intermediate film enables ultraviolet rays to penetrate solar cells and improve the efficiency of solar cells; The tear strength and rigidity are 5 times and 100 times of the traditional glass interlayer respectively; Excellent impact resistance and structural performance over a wide temperature range

DuPont's recent innovative research and development also includes DuPont solamet, a lead-free and cadmium free thick film technology conductive paste specially used for solar cells. This new lead-free conductor paste system is not only more environmentally friendly, but also provides excellent electrical performance and higher reliability for solar modules. DuPont Rynite pet thermoplastic resin is suitable for demanding applications. For example, strength and key endurance are necessary for PV junction boxes. It can be used to manufacture modules that are firm, durable and dimensionally stable. The combination of these different high-performance plastics or engineering plastics makes today's solar energy technology mature day by day

DuPont is not the only manufacturer developing solar related modules. Honeywell recently developed a new material that can protect photovoltaic solar cells in harsh environments. The new product is called Honeywell powershield pv325, which can protect PV components in humid and other environments, including the main components that convert light energy into electric energy. The product is not only UV resistant, moisture-proof and aging resistant, but also can withstand the power load generated by components with working voltage up to 1000 V. Honeywell powershield is mainly developed for rigid PV components, which are specially used to supply power to public facilities or local electricity. The service life of such elements is usually 25 years, which can act as a reliable power supply during the power failure of public facilities, and can cover the peak power demand and related costs. Honeywell powershield adopts a five layer design, including two outer protective layers based on ethylene chlorotrifluoroethylene (ECTFE) fluoropolymer film, a polyethylene terephthalate (PET) intermediate layer, and an inner adhesive layer composed of two proprietary adhesive materials. It provides PV component manufacturers with an alternative product of PVDF back plate material

with the attractive charm of laser printed circuit

in the second industry of retail and goods management, wireless tag or RFID transponder is considered as the future technology. In order to simplify and speed up the logistics process, RFID tags are often used on containers, packing cases and crates to provide information on contents, origin and conditions

recently, HARTING mitronics Ag successfully improved the efficiency and detection range of RFID transponder. It uses laser direct line forming (LDS) technology to manufacture three-dimensional plastic printed circuits (also known as in mold interconnection devices, mid), and develops a new generation of transponder. This product is manufactured by pocan DP t7140 LDS of LANXESS

laser direct line forming technology is a special innovative technology for manufacturing mid. Using this technology, we can flexibly and conveniently manufacture printed circuits on three-dimensional mid at a lower cost than "plastic restriction order" to "plastic sales order", without using chemical etching. The process uses thermoplastic, in which organic metal compounds are added. After injection molding, high-resolution circuit diagrams are "fired" on three-dimensional components by laser. Subsequently, copper, nickel and/or gold circuits are plated on the activated areas in a chemical plating metal bath

pocan DP t7140 LDS developed by LANXESS can meet the requirements of all LDS processing processes from injection molding and laser etching to plating and possible subsequent welding. Its thermal deformation temperature is 250 ℃, which is especially suitable for high heat environment. The polymer can also withstand the high temperature of reflow welding and gas phase welding. LDs and mid technology are combined to realize the integration of 3D directional antenna on plastic parts. Different from the traditional wireless tag made of plastic film, i.e. smart tag, with this antenna, the RFID transponder can read and write within 5 meters, even when it is close to metal and liquid

BASF recently provided a new laser Engravable polyamine to EMW antenna, a leading antenna manufacturer in South Korea, to develop the world's first plastic micro antenna for GPS and Bluetooth. Ultramid t 4381 LDS is a partially semi crystalline and aromatic high temperature resistant polyamine 6/6t, which is reinforced by 10% glass fiber and 25% mineral filler, providing a wider range of metallization without damaging its mechanical properties. Compared with conventional ceramic materials used in micro antennas, Ultramid t 4381 LDS has a wider frequency range and a lower voltage standing wave ratio (VSWR) than ceramic micro antennas, thereby improving antenna performance. In addition, it can reduce the cost by reducing the defect rate and manufacturing process

Evonik has developed special PMMA series products for the backlight device of TFT-LCD display

innovative application promotes the research and development of new materials

besides the traditional fields of automobile, electronics, medical treatment, household appliances and other common concerns, engineering plastics have innovative applications in the fields of train, safety protection, water treatment and so on

as a means of transportation with strong transportation capacity, the passenger environment of the railway train is relatively complex, and there are high requirements for the interior walls and ceilings of the train in terms of flame retardance, pollution resistance, smoke pollution, etc. For the wall and ceiling coverings of railway trains, xantar C CE 407 (pc+abs) materials from DSM engineering plastics are used for coextrusion of substrates. The surface of the product is provided with a very thin polyvinylidene fluoride (PVDF) surface layer, which is then thermoformed. This material can meet the strict restrictions of DIN standards on flammability, smoke and toxicity, and does not contain chlorination and bromination additives. Its chemical resistance helps to simply remove graffiti from the walls at will by passengers

in order to meet some high requirements, such as toe protection cap of safety shoes, Bayer Materials Technology Co., Ltd. has introduced a hard, impact modified makroblend DP 6015 (pc+pbt), which conforms to DIN EN 345 standard for safety shoes. One of its requirements is to maintain mechanical properties even after exposure to chemicals. The standard specifies a drop test method: an axe sample falls on the toe cap with 200 joules of energy at -20 ℃ and 60 ℃ and tests its deformation. Toe protection caps are required to pass this test after being immersed in gasoline, dilute sodium hydroxide and dilute sulfuric acid for 24 hours. For the extremely hot and humid environment, Bayer materials technology has developed a halogen-free flame retardant pc+abs mixture, bayblend DP 3008 HR (HR refers to hydrolysis resistance). This flame retardant combination product does not contain bromine and can meet the requirements of major environmental directives, including "TCO 05" and "Blue Angel". The accelerated aging test aimed at simulating the actual life cycle of household appliances shows that the effect of anti hydrolysis is excellent. Potential applications include tipper dryers, front panels on dishwashers and washing machines, battery housings, and components for monitors and laptops in hot, humid climates

in the field of water treatment, Germany's neoperl company produced the world's smallest plug inflator "perlator TT". This product utilizes tycona's Hostaform ACS (polyoxymethylene). The main requirements here are high resistance to common household cleaning agents and not easy to be contaminated by bacteria in the case of fine structure. In order to adapt this product to the export demand to different countries and promote the production and logistics process of cock manufacturers, a special color coding system has been developed, which is implemented by Hostaform

in order to make the mixture of metal and plastic of nano lattice can be used commercially, DuPont has formed an alliance with two Canadian companies, morph technology company and integral technology company, as well as power metal technology company of the United States. Metafuse patented technology can apply a layer of high-strength nano metal coating on components made of DuPont engineering plastics. This mixture has the same toughness as magnesium or aluminum, and is even stronger than them. This technology directly produces an integrated metal package using crystalline coarse grains. The initial development targets the automobile industry, consumer electronics and sporting goods

Evonik developed the colored molding compound Plexiglas cool touch (PMMA) because it can reflect infrared rays and reduce the heat release of dark plastic surfaces by 20%. Possible uses of this molding compound include body parts and roof elements, ceiling materials, window frames and decks. Less heat release reduces the operating cost of the air conditioning system. Plexiglas poq is a PMMA with a conductivity exceeding 92%, which can be used for the backlight assembly of flat panel displays. By producing and repacking this material under clean room conditions, this light guide performance is ensured

energy conservation and environmental protection meet the development needs of the industry

as an advanced material with energy-saving potential, engineering plastics show their outstanding advantages in increasingly stringent environmental and climate demands. Climate change, stricter emission standards, and higher safety and comfort requirements have made various energy-saving and environmental protection products an important direction of industry performance research and development
