The ULTEM resin family of amorphous thermoplastic polyetherimide (PEI) materials offers outstanding elevated thermal resistance, high strength and stiffness, and broad chemical resistance. These materials uniquely balance both mechanical properties and processability, offering design engineers exceptional flexibility and freedom.
Invented by Saudi Basic Industries Corporation, known as SABIC and General Electric, ULTEM
resins retain strength and resist stress cracking when exposed to automotive and aircraft fluids.
The frame is so extraordinary light that it is hardly felt when worn.

With special property of resistance of stress cracking when exposed to aliphatic hydrocarbons, alcohols, acids, and weak aqueous solutions, ULTEM is used in medical, scientific, and laboratory environment.
Excellent stability of physical and mechanical
properties at elevated temperatures.
