About Polyetherimide(PEI) ?

PEI(Polyetherimide) is an amorphous thermoplastics resin, which has special features, such as high heat resistance, flame retardant and low smoke etc. [manufacturer: SABIC(Saudi Basic Industries Corporation), trademark:ULTEMTM]
Kuraray has succeeded in manufacturing the ‘PEI Fiber’ with our original spinning technology.
This is a new high heat resistance and flame retardant fiber which has several unique properties, such as fine dr, low smoke density and good dyeability.
<KURAKISSS> can be used in many applications.
The most important concept of <KURAKISSS> is quite simply "the provision of safe and secure environment."
