Performance Features
Vyntec® can deliver cost savings compared to high-end thermoplastics such as PEI and PEEK without any reduction in performance. In fact, tests show that Vyntec® performance can not only match that of high cost materials but in many instances is superior to them.
Vyntec® is characterized by its unsurpassed combination of properties. Through the use of lightweight carbon fibers, Vyntec® exhibits low density, between 1.35-1.55 g/cm3, giving it a high stiffness/density ratio. Moreover, optimum impregnation of carbon fibers endows the material with high thermo-mechanical properties and chemical resistance, even at elevated temperatures.
Underpinning its performance profile are Vyntec's® outstanding tribological properties, which provide it with a very high level of resistance to wear, together with a low coefficient of friction at high temperatures. This gives the material an excellent fit in applications where one or more interconnected parts are in motion, and particular value in applications where the lubrication of moving parts is either precluded or undesirable. This characteristic opens the way for Vyntec to fulfil the operating criteria of applications such as rotors and propellers in vacuum and fluid pumps, various types of bearings, as well as seals in brake and engine systems.
Furthermore, because Vyntec® consistently maintains its surface properties and mechanical performance at a continuous in-use temperature of 150°C, a level at which the performance values of many engineering thermoplastics are reduced or fail, its potential use extends to a broad range of harsh environment automotive and industrial applications for which long-term, robust performance is demanded.
