What is ULTEM™ PEI SBAIC-IP Polyetherimide

1. Ultem™ PEI SBAIC-IP Polyetherimide Overview

ULTEM plastic PEI (formerly U.S. GE) transparent amber PEI is an amorphous characteristics of extraordinary polymer, is produced with amorphous PEI processed rubber and plastic products through the flame retardant plastic machine high temperature extrusion molding. The current common PEI board is the use of raw materials from the United States GE (trade name Ultem), the United States GE company in 1972 as soon as the scientific research design and development of PEI. characteristics: PEI is characterized by high tensile strength at high temperatures, high bending stiffness, wear resistance and specifications credibility. PEI is a dark brown transparent solid, no longer add all additives will have the original fire rating and low smoke The density of PEI is 1.28~1.42g/cm3, the coefficient of linear expansion is 215℃, the heat deflection temperature is 198~208℃, it can be used for a long time at 160~180℃, and the allowable intermittent use temperature is 200℃. PEI has high quality fracture toughness, insulation layer characteristics, resistance to radiation hazards, high and low temperature resistance, It is resistant to radiation hazards, high and low temperature resistance and fatigue resistance, and molding performance; coupled with glass fiber, carbon fiber or other fillers to ensure that the purpose of upgrading modified engineering plastics.

PEI has two versions, ULTEM 1010 and ULTEM 9085. the differences are subtle. ULTEM 1010 is stiffer, while ULTEM 9085 has better impact resistance.

While ULTEM 1010 has a proven track record in the medical and food industries, ULTEM 9085 is more popular because of its long-term use in aerospace interior components through additive manufacturing. ULTEM 9085 is known for its FAR 25.853 certification, issued by the FAA for aircraft interiors

2. ULTEM™ PEI SBAIC-IP Polyetherimide Properties

(1)Composition and structure: PEI is mainly composed of polyetherimide, of which polyetherimide is a polymer with a highly cross-linked molecular structure. This cross-linked structure makes PEI have high thermal stability, chemical inertness and corrosion resistance.

(2)Physical properties: PEI has excellent mechanical properties, including high strength, high stiffness and good fatigue resistance. It has high tensile strength, bending strength and impact strength, and it can still maintain high strength at high temperature. In addition, PEI also has good wear resistance, scratch resistance and chemical resistance.

(3)Thermal properties: PEI has good processing properties and can be processed by various methods such as injection molding, extrusion and compression molding. However, compared with other engineering plastics, PEI is more difficult to process and requires the use of more special processing equipment and processes.

3. ULTEM™ PEI SBAIC-IP Polyetherimide Application
