Duratron ® U 1000 PEI Unfilled

Duratron® Polyetherimide (PEI) is family of transparent amber high-performance polymers that combine high strength and rigidity at elevated temperatures with long term heat resistance. PEI offers excellent dimensional stability combined with broad chemical resistance.  Duratron® PEI grades are commonly machined into parts for reusable medical devices, analytical instrumentation, electrical/electronic insulators (including many semiconductor process components) and a variety of structural components requiring high strength and rigidity at elevated temperatures. Mitsubishi Chemical Group offers Duratron® U1000 PEI and Duratron® U2300 PEI as standard products.Pei Ultem Sheet Rod

Duratron® U2100 PEI Polyetherimide shapes are 10% glass-reinforced, giving them greater rigidity and dimensional stability over Duratron® U1000, as well as a low coefficient of linear thermal expansion. With an excellent strength-to-weight ratio and high tensile strength, this grade is ideal for for semiconductor and electronics applications.

Material Properties

10% glass reinforced for added rigidity and dimensional stability

High strength

Excellent flame and heat resistance

Consistent dielectric properties over wide frequency range

Resistant to hydrolysis and acidic solutions

Suitable for repeated autoclaving

2.Duratron® U2300 PEI

Duratron® U2300 PEI is a flame resistant Polyetherimide that is 30% glass-reinforced, allowing this grade to exhibit the highest rigidity, strength, dimensional stability, and heat resistance of all Duratron® PEI shapes. Possessing the lowest Coefficient of Linear Thermal Expansion (CLTE), and superior strength-to-weight ratio and tensile strength, this grade is favored as a solution for reusable medical devices, analytical instruments, electrical insulators and semiconductor process components, and structural components that require high strength and rigidity at elevated temperatures.

Material Properties

Acid and steam resistant

High strength and rigidity at elevated temperatures

Dimensionally stable

30% glass-reinforced

Possesses the lowest Coefficient of Linear Thermal Expansion (CLTE)

3.Duratron® U2200 PEI

Duratron® U2200 PEI Polyetherimide shapes are 20% glass-reinforced, giving them exceptional rigidity and dimensional stability, high temperature resistance, and a low Coefficient of Linear Thermal Expansion. With an exceptional strength-to-weight ratio and increased tensile strength, this grade is also a great electrical insulator for semiconductor and electronics applications.

Material Properties

20% glass-reinforced
