Ultrason® KR 4113

Ultrason® KR 4113 is a medium viscosity, high-temperature resistant, amorphous thermoplastic derived from polyethersulfone (PESU) reinforced with 30 % carbon fibre, graphite and PTFE powder. It is insoluble in water. Exhibits improved tribological properties, very small expansion coefficient, low tendency to swell in hot oil, outstanding thermal stability, creep strength at high temperatures, resistance to fracture, superheated steam, oil, fuel, fluorine & coolants, good toughness & impact-resistance, high stiffness, good dielectric properties, high mechanical strength, very good fire behavior, excellent hydrolysis resistance, high resistance to thermal aging, very high long-term service temperature, resistance to weathering, good dimensional stability and good electrical insulating capacity. Can be processed using injection molding and extrusion. Applications include automotive construction, household sectors, and electric & electronic components. It complies with the EU Directive 2006/122/EC (PFOA), EU Directive 2011/65/EU (RoHS) and EC Regulation 1907/2006 (REACH).
