Vespel rods is a top-grade engineering plastic profile with really impressive physical and chemical properties. Polyimide, or PI for short, is a newer type of high-temperature resistant, heat-setting engineering plastic. It keeps its strength and mechanical performance across a huge temperature range from -269°C to 400°C, and can even operate long-term in air between -240°C and 260°C. On top of that, it offers a full package of benefits like oxidation resistance, radiation resistance, corrosion resistance, moisture and heat tolerance, high strength and stiffness, and great dielectric properties.
