Description:
AvaSpire AV-755 SL45 is a wear resistant grade of AvaSpire PAEK designed to provide low wear rates and high pressure-velocity (PV) tolerance in lubricated wear environments. Like the other members of the AvaSpire AV-700 series, AV-755 SL45 offers more attractive economics than PEEK while retaining most of PEEK's key attributes. In addition to the outstanding wear resistance the resin also offers the outstanding combination of chemical resistance, mechanical strength and stiffness at elevated temperatures, as well as long-term and high temperature thermal-oxidative stability.
AvaSpire AV-755 SL45 is formulated with a binary anti-friction/anti-wear additive system comprised of carbon fiber and graphite. By virtue of its additive system, this resin also offers exceptionally high stiffness and very low moisture absorption.
Potential applications for AV-755 SL45 include bushings, bearings, wear strips, wear rings, rollers, and other parts used in sliding friction components. This high flow (low viscosity) resin is black.
AvaSpire PAEK is a family of high-performance between PEEK and other high-performance polymers.
For example, ductility and toughness can be significantly improved versus comparable grades of PEEK, delivering 20% higher tensile elongation at yield and doubled tensile elongation at break values.
Depending on the grade, AvaSpire PAEK outperforms comparable grades of PEEK.
