Description
Overview
ULTEM® 1000 is an amorphous polyetherimide (PEI) and is one of the most widely used high-performance materials. It offers exceptional thermal performance and high mechanical strength and stiffness. ULTEM® 1000 is inherently flame retardant, possesses good resistance to acids, and is capable of continuous operation in steam and hot water environments.
Polyetherimide is characterized by its high heat resistance, high strength, and modulus, as well as excellent electrical insulating properties that remain stable across a wide range of temperatures and frequencies. The material is transparent with an amber tint in its unmodified form and exhibits low moisture absorption, providing excellent dimensional stability.
