Material: PSU 1000

PSU 1000 stock shapes are produced from non uv-stabilised polysulophone resin. High max allowable service temperatures, high strength and stiffness, excellent hydrolosis resistance, dimensional stability and resistance against high energy radiation (gamma and x-rays). Good electrical insulating and dielectric properties. Compared to PEI 1000 it has a lower property profile often replacing polycarbonate when a higher temperature resistance and improved chemical resistance are required.
