Ultem® 2300 (30% Glass Filled Polyetherimide)
Ultem® 2300 is a glass fiber reinforced high performance engineering thermoplastic polymer that provides superior strength and stiffness. It has excellent chemical resistance and has a continuous service temperature of 340 degrees F. It is easily machined with conventional metal working equipment and can be machined to very close tolerances. Both sheet and rod are available in many thicknesses and diameters. Rod stock comes ground to diameter to accommodate through spindle turning. Standard colors are tan and black, and custom colors are available only as custom runs.
Ultem® 2300 enhanced structure increases its rigidity and improves dimensional stability while maintaining many of the useful charactoristics of unfilled Ultem. Also, since it is an amorphous material, care needs to be taken if machined with coolant. If used, non aromatic coolants should be used to avoid crazing.
