Du Pont Engineering Polymers of the United States launched a series of new engineering plastic products at the 2003 National Plastics Fair (NPE 2003) with the goal of improving the appearance of products and improving processability and production efficiency. New materials include: thermoformed polyoxymethylene, electroplated and coated grade polyoxymethylene, high-gloss paintable thermoplastic polyester for automotive bodies, and electroplated nylon. In addition, there are semi-permeable membranes for hydration devices, two flame-retardant nylon grades for electronic and electrical appliances, and one processing aid, and publishes the results of pilot tests for the recovery of large glass-reinforced nylon auto parts.
The successful development of thermoformed polyformaldehyde Delrin Labeled means that customers can use POM to thermoform decorative panels, various shells and other products. Polyoxymethylene has better chemical resistance and lubricity than competing materials such as polycarbonate or ABS resins, and parts can be painted, printed, applied in a die coat and foiled or otherwise decorated. Du Pont's Penn Fiber Corporation currently supplies thermoformed Delrin boards, and California-based Freetech Plastics is an early developer of industrially produced products using this material. Du Pont's vice president of technology, Hsu, introduced the technical issues involved in the complete decoration of Delrin products, including suitable polyformaldehyde resins, surface treatment (etching) methods and three kinds of paints and lacquers, as well as the processing of "no plastic appearance" gloss and coating. Paint, metallized parts technology. After the etching solution acts on the surface of the part, it can adapt to the next step of the Du Pont coating process. Future applications include snowboard protection and trunk waterproof covers, automotive horns and exhaust grilles, pipe clamps and cosmetic packaging.
High heat-resistant thermoplastic polyester Rynite Shine-E application targets paint automotive body panels and unpainted applications. According to the introduction, the body panel formed of this material can be painted next to the metal body panel and painted on the automotive paint line including the furnace at 220°C to obtain Class A standard products. Polyester not only has excellent gloss, high temperature resistance and luster, but also has extremely high dimensional stability, because its moisture absorption is extremely small, and the unpainted products directly from the mold are mainly used for home appliances.
Two electroplated nylon grades Zytel HTN can improve the appearance of the product, is a substitute for the metallized screen, as a suitable material for ABS or some other electroplated plastic due to performance, (such as heat resistance, rigidity or chemical resistance), and The cost is lower than high-performance engineering plastics.
Du Pont also introduced two flame-retardant glass-reinforced nylon Zytel grades, replacing thermosetting plastics, for integrated circuit automatic circuit breaker housings, gear switches, and fluorescent lighting applications. In addition, the company also introduced the non-enhanced nylon 66 resin grade Zytel FE 310014, which acts like a processing aid, shortens the nylon molding time, and in particular accelerates the molding of complex-shaped parts. At present, the supply market is based on pellet masterbatch.
Du Pont also cooperated with Denso Corporation, a Japanese auto parts supplier, to conduct a mid-composition based on composite material recycling. The results of the test were announced at NPE 2003. According to the regulations of the European Community recycling and closed-loop utilization of waste cars, the project involves large-scale recycling. Glass-reinforced nylon car parts, currently implemented at the tank end tank recovery facility in Canada, currently have technology that also “provide re-work†tanks, allegedly this technology will also be used for air intake manifolds and other glass fiber reinforced and Inorganic filled thermoplastic parts.
