The global shortage of polyetherimide (PEI) is being addressed by RTP Company offering a number of thermoplastic compounds that serve as viable alternatives. These compounds include amorphous materials based on sulfone or semicrystalline materials that have been modified, alloyed, and/or reinforced to achieve very similar physical properties to PEI. Engineers from RTP Company can customize and fine-tune these compounds to meet specific application requirements including offering compounds in custom colors.
“Since the supply of PEI has tightened, molders and OEMs have been forced to manage risks such as long lead times and supply disruptions,” explains Matt Torosian, RTP Company Product Manager of High Temperature Materials. “RTP Company has created a range of compounds with similar characteristics to PEI that are not dependent on a single supplier of base resin. By doing so, our customers have benefitted from a larger selection of material options, greater design flexibility, and far fewer interruptions in material supply.”
Because PEI has excellent dimensional stability, chemical resistance, strength, stiffness, inherent flame retardancy and creep resistance, selecting a replacement requires a thorough understanding of the application requirements. Once these requirements have been identified, RTP Company engineers can recommend compounds that fit the requirements, along with added benefits such as color. To support transition to a new material RTP Company provides on-site technical service and CAE support including mold flow analysis, FEA and fiber orientation analysis.
