Compound withstands high-pressure refrigerants
-
A PEEK-based specialty compound from Victrex USA, Inc. is used in scroll compressors for Visteon's automotive air conditioning systems. The compound gives the compressor's tip seals the durability, stiffness, and wear resistance necessary to prevent refrigerant leakage between chambers of differing pressures. Contacted by the molder, QMR Plastics, RTP Company engineers worked to develop an RTP 2200 Series PEEK-based compound that offered the right combination of wear resistance, stiffness, and high-temperature performance. Tensile strength of the compound is 138 MPa (20 ksi) and flexural strength is 220 MPa (32 ksi).
