Ultem PEI Plastic Sheet & Rod

PEI (Polyetherimide) is an amorphous, transparent amber-colored high-performance thermoplastic. Its molecular structure contains both aromatic amine functional groups and ether linkages, making it a more cost-effective and higher-yield thermoplastic polyimide (PI) compared to other aromatic PIs. Additionally, PEI can be further enhanced by incorporating glass fibers or other modifiers.

PEI Product Overview

JTYPEI®NA is a PEI-based material produced from pure polyetherimide resin. As an amorphous polymer with a glass transition temperature of up to 215°C, it exhibits mechanical properties comparable to PEEK, along with excellent heat resistance, insulation, and flame retardancy.

This product is suitable for high-stress, fatigue, or impact-load environments, such as:

Automotive components (interior/exterior parts)

Semiconductor manufacturing

Precision bearings

Mechanical load-bearing parts

Wind power equipment & new energy battery components

Electrical systems
