Introduction to the application of PEEK high-performance polymer in gears
The main trends in the industry are: improving performance and efficiency, reducing weight and miniaturization while reducing costs. In gear applications, engineers are looking for new materials to replace existing metal materials or to improve typical polymer material solutions to meet the high performance requirements of future systems. In recent years, PEEK high-performance polymer materials have been successfully used as an alternative material in a wide range of applications in multiple industries. In response to the continued development of this trend, Changzhou Junhua has sufficient resources to provide customers with direct assistance in processing, design and application development. Performance: Gears have to meet multiple complex requirements because different types of loads always occur simultaneously. The proper operation of gears depends…

High-quality PEEK thrust washers for demanding applications
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…

Celanese thermoplastic composite wire can replace metal materials
Celanese thermoplastic composite wires can replace metal materials Celanese Corp. and US wire and cable manufacturer Southwire Co. LLC have developed an overhead transmission line made of thermoplastic composite materials to replace traditional wires with aluminum conductors and steel reinforcement. 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…

Victrex PEEK polymer global price increase
On August 15, 2014, Thornton Cleveland, the high-performance polyaryletherketone solutions division of Victrex, announced that it would increase the price of its VICTREX polyaryletherketone polymer products by at least 6.8% from October 1, 2014 (or as required by the contract), to account for the rising costs of major raw materials such as hydroquinone and to compensate for the increased costs of energy, freight and inflation. As the cost of raw materials and labor increases, the company will control costs by reducing consumption, optimizing processing technology, etc. to minimize the impact on customers. PEEK (polyetheretherketone) has the advantages of high temperature resistance, wear resistance, corrosion resistance, self-lubrication, high strength, hydrolysis resistance, flame retardancy, radiation resistance, and dimensional stability. It is widely…

Friction and wear characteristics of PEEK
Junhua PEEK Technical Data: Introduction to the Self-lubrication, Friction and Wear Characteristics of PEEK 1. Friction is the interaction between contacting surfaces when they move relative to each other under the action of external forces. When observing the surface of a material that looks very smooth under a microscope, you can see obvious bumps and depressions. Therefore, if two materials are in contact and move relative to each other, the rough granules on the surfaces of the two materials will collide with each other, and the disappearance of the rough granules can be defined as wear. 2. PEEK has outstanding sliding properties among all plastics. It can provide excellent wear resistance under various temperatures, pressures and relatively rough contact surfaces….
