- Polymer Name:Polyether Imide (PEI)
- Functions:Prepreg
TU400 is a polyetherimide (PEI) fiber-reinforced uni-directional tape that processes is in the 660-710oF (350-375oC)temperature range. The prepreg is used in a variety of high performance, structural composite applications. PEI is an amorphous polymer that provides high temperature resistance, toughness and superior FST properties.
