El alambre compuesto termoplástico de Celanese puede reemplazar materiales metálicos
Celanese Corp. and U.S. wire and cable maker Southwire Co. LLC have developed an overhead transmission line made of thermoplastic composites to replace traditional wires that use aluminum as conductors and are reinforced with steel. The transmission line, called C-7, uses a composite core of bundled strands made of Celstran long-glass fiber-reinforced thermoplastic combined with heat-resistant Fortron polyphenylene sulfide and is covered with a layer of PEEK (polyetheretherketone). The cable harness is housed in a sheath made of aluminum or aluminum-zirconium alloy. Celanese and Southwire Corp. introduced the lightweight composite wire earlier this year after seven years of development. Celanese demonstrated the application at the JEC Americas Composites Show in Atlanta in May. Benefits include reduced increase in sag…

La resistencia a altas temperaturas del PEEK mejora el rendimiento de los palitos de mordida dentales
When Dentronix, a subsidiary of the Swiss Coltene/Whaledent Group, was designing a new “heat-resistant” bite bar, it needed a material that could withstand the high temperatures of a dry heat sterilizer. The company chose PEEK, a high-performance polymer used in a variety of high-end medical applications, because of its good overall performance. Bite bars are orthodontic tools used to secure braces to teeth. The orthodontist places the braces on the patient’s teeth and then places the bite bar, which allows the metal insert to help the braces slide into the correct position when the patient bites down. Since bite bars mechanically secure braces to teeth, impact strength is important, and PEEK polymer meets the requirements for bite pressure. A requirement…

Normas de clasificación y métodos de ensayo para PEEK aislante, conductor y antiestático
Introduction to the classification standards and measurement methods of insulating, conductive and antistatic PEEK — Changzhou Junhua PEEK Co., Ltd.: Zhang Chengxiang and Tan Zongshang 1. Overview Pure PEEK is an insulator with outstanding high and low voltage resistance, and can maintain its electrical properties in a wide range of temperature and frequency. However, in special industries such as electronic semiconductors, static electricity accumulation generated during the production process can absorb dust, causing electronic devices to break down and damage, or even lead to major accidents such as explosions and fires. This requires that PEEK rollers, PEEK vacuum pen tips, etc. must not only have the advantages of high temperature resistance, wear resistance, and high strength, but also have anti-static…

Arandelas de empuje de PEEK de alta calidad para aplicaciones exigentes
Lighter weight, smaller size, more power, more functionality, better performance, longer life, higher energy efficiency, reduced CO2 emissions and lower overall costs – this is a major trend in today’s transmission manufacturing, just like in other areas such as automotive engineering. Thrust washers are an important part of the transmission. Since they separate the different gears, they are subject to large axial forces and extremely high friction loads. The compact design of the housing, high pressure (P) and high speed (V) increase the oil temperature. Wear-resistant materials such as polyimide (PI) and polyamide-imide (PAI) cannot meet these extremely demanding requirements. The high-performance polymer PEEK has a good performance in thrust washers and is therefore a mature alternative to PI, PAI…
