Engineering Plastic

PEI Engineering Plastic

PEI (Ultem® 1000) is an amorphous polyetherimide. Due to the material's properties, PEI is one of the most commonly used high-performance materials available. It offers excellent thermal performance and high mechanical strength and stiffness. It is naturally flame retardant, possesses good resistance to acidic solutions and is capable of operating continuously in steam and hot water. PEI GF 30 is 30% glass-reinforced and provides extra stiffness, strength and dimensional stability for more demanding applications and working environments. We also process your PEI material in-house at Smiths.

PEI is in inherently flame-resistant which widens the scope of use for this material in numerous applications.

Typical Applications

Commercial applications for this engineering material include:

  • Aircraft components
  • Semiconductors
  • Fluid handling systems
  • Analytical instrumentation
  • Medical devices

We stock PEI in round bar, plate and sheet.
