Looking at the development of high-end engineering plastics from iphone5c

at 1 a.m. on September 11, apple officially released iphone5s and 5C at the autumn new product launch, of which iphone5c was made of polycarbonate for the first time and provided a variety of color options. Polycarbonate is one of the five engineering plastics (polycarbonate, polyformaldehyde, polyamide, thermoplastic polyester, modified polyphenylene oxide) with good light transmittance, impact resistance, UV radiation resistance, dimensional stability and good molding and processing performance. China's production capacity is seriously in short supply, and a large number of imports are required every year, with a self-sufficiency rate of less than 20%. Apple used polycarbonate for the first time, marking the further expansion of the use of high-end engineering plastics in the electronic field. We believe that the development space of high-end engineering plastics is broad. In addition to electronics, there is also a large expansion space in the automotive and medical fields, and it will be linked with the concepts of automotive lightweight and new medical devices. At the same time, it is also a cheap and rich C1 resource. Therefore, the theme of this issue is to introduce the development trend of engineering plastics, and extract the latest development of high-end engineering plastics in automotive, medical and other fields

from the perspective of iphone5c, the development of high-end engineering plastics

in the automotive field, high-performance polyamide resins will further replace metals: energy conservation and emission reduction is one of the development directions of the automotive industry. Compared with traditional metal materials, new modified plastics can reduce the vehicle weight by% and reduce carbon dioxide emissions while saving fuel. Chery recently selected DuPont high-performance polymer unit as its fixture mechanism: according to the tested product automotive plastic supplier, high-performance polyamide resin, ethylene acrylic elastomer and other composite materials will be applied in air inlet, cylinder cover, ventilation pipe and other automotive parts, and the improvement of plastic strength will gradually replace metal

in the medical field, polyurethane elastomers have excellent biocompatibility and stronger mechanical properties: human tissue and blood pose considerable challenges to the elastic materials implanted in medical devices. Such materials must be able to be exposed to adverse aqueous environment for a long time under human body temperature, and minimize the complications of patients, reduce coagulation, rejection, and anti lightweight design, which puts forward a lot of new requirements for the utilization of plastic materials Tissue inflammation and toxic chemicals enter the body. Polyurethane elastomers have excellent related properties. Some models, such as pellethane aromatic polyether type 80a-75d, are used in infusion tubes, infusion tube drip buckets, indwelling needle extension tubes, and incision protective sleeves. Tecoflex aliphatic polyether type 72a-83d is used in central venous catheters, catheters, nasal feeding catheters, endoscopic catheters, and cardiac assist devices, and there is a huge space for long-term development. Unless the weight of the sample measured by your experimental machine is particularly large
