General-purpose and application-specific properties

High-temperature capability (long-term). One of the features of Aurum is excellent long-term heat capabihty at elevated temperatures. Long-term heat resistance is usually represented by the retention of properties after the specimens are exposed to high temperatures. Table 10.3 shows the

Wear and friction properties. Aurum grades, where Mitsui s unique compounded materials are based on the proper selection of matrix, fillers, and additives, have excellent wear and friction properties. Aurum has both outstanding wear resistance and low friction even at 302°F (150 C) in dry conditions. The PV limit, which can show the maximum capability of high load and high speed, is the highest of all thermoplastics in dry environments (100 kpsi m) (Table 10.4). 

Moreover, its tribological properties are exceptional under oil conditions since the coefficient of friction is surprisingly low and stable in oil. This is why Aurum can withstand high-duty loads. 

Chemical resistance. Aurum is widely regarded as a material with outstanding chemical resistance, and it has a remarkable resistivity against oil, even at elevated temperatures. The properties and appearance of Aurum do not change even under harsh conditions such as 392°F (200°C). Therefore, the stable properties are guaranteed under ordinary usage conditions, such as below 302°F (150°C).
