Product features

DOCAPEI GF30 has the properties of natural PEI with the added benefit of greater dimensional stability due to the fibreglass reinforcement.

Amber opaque

DOCAPEI (PEI) product family features

The excellent chemical resistance and good insulating properties of PEI, or polyetherimide, make it an important choice where mechanical strength or heat resistance may also be required (albeit at a lower level than PEEK, for example). It is also known as Ultem. Available in sheet and rod formats. In addition to the standard amber colour, black and blue are also available in certain sizes. The glass fibre reinforced version (glass fibre PEI, PEI GF or GF30) also meets higher mechanical demands, although it is available in a smaller range of sizes than the basic version.

Some important features

High strength (50-105 MPa yield strength, tensile strength and compressive strength)
High toughness - does not break
Wide application temperature range: -50°C to +210°C
Very good chemical resistance compared to PA, POM, PET
Physiologically neutral, may come into contact with food and medicines
High hardness (Rockwell: M 75 - M 114)
Dimensional stability, good damping capacity
Favourable creep resistance (10-30 Mpa for 1% stretching at 23°C for 1000 hours)
Good electrical insulating and dielectric properties
Good resistance to high-energy radiation

Main areas of application

Machine components and sub-assemblies, especially in the food industry and medicine, which need to be cleaned and sterilised frequently.

Machining technology

Chipping (turning, milling, drilling, sawing): conventional tools can be used, but only with a sharp finish. Cooling is recommended, with cutting speeds of v = 200-400 m/min for turning and milling, v = 50-100 m/min for drilling.

Gluing: is feasible (but more difficult than PVDF with similar properties).
