Ultem PEI Plastic

PEI plastic or polyetherimide is an amorphous material that shows high mechanical properties, high thermal resistance, and great electrical performance. The PEI is also named Ultem because Keward uses Sabic’s Ultem® resin as raw material for extrusion. The Ultem virgin is a translucent amber color plastic with high rigidity and good dimensional stability. The material is widely used in the electronic, telecom, and mechanical industry.

The Ultem 2300 or PEI GF30 is plastic by adding 30% glass fiber based on PEI virgin. The glass fiber reinforced the tensile strength and rigidity. The higher modulus also increases the dimensional stability.
