PEI Extruded Natural Rod is a transparent amber, amorphous thermoplastic with product characteristics including high rigidity even at high temperatures, very low smoke emissions and high resistance to high energy radiation. The long term service temperature range of PEI Rod is from -50°C to 170°C and has a short term maximum service temperature of 210°C. The physical properties remain virtually unchanged in a broad temperature and electrical frequency range. Typical fields of application for PEI Rod include electrical and electronic industries, medical technology and aerospace engineering. PEI Rod is a material well suited to billeting, precision grinding and CNC turning. Similar materials available from Plastock include PSU Extruded Natural Rod and PEEK 450G Extruded Natural Rod.
