High-performance resin with improved friction characteristics

12 January 2010

Compared with all previous versions of BASF’s high performance resins, Ultrason KR 4113 polyethersulfone offers considerably improved friction performance. This is achieved by incorporating carbon fibres, graphite and PTFE (polytetrafluoroethylene). The feature was measured  for the first time by Nanoprofile GmbH in Kaiserslautern, Germany, which specialises in tribological investigations.

While the wear rate for classic Ultrason E 2010 is about 420 (10-6 mm³ N-1 m-1), the carbon-fibre-reinforced Ultrason E 2010 C6 has a value of only 3.0 and Ultrason KR 4113, one of only 1.5. In this case, the experts at Nanoprofile conducted unidirectional sliding wear tests using the ring-on-plate principle. In this test, a plastic specimen under high load slides against a ring-shaped counterbody of hardened chrome steel at a defined speed under non-lubricated conditions, the value measured being the penetration of the counterbody into the test specimen.
