PLASTMASS™
PEI PLASTIC

Thermoplastic perfect for affordable sliding parts.

PLASTMASS™ PEI plastic (polyetherimide) is ideal for the production of sliding parts that work at higher temperatures, speeds and loads than PET. The use of PLASTMASS™ PEI reduces friction, wear and works in dry operation. It is a robust material that lowers operating costs and is also cheaper than (polyetheretherketone) PEEK. Our plastics are manufactured under high quality standards in our factory in Russia.

FEATURES OF PEI

  • At temperatures up to 180 °C hard, stiff and tough

  • Good durability

  • High dimensional stability

  • High chemical resistance

  • High hydrolysis resistance

  • Very high UV radiation resistance

  • Excellent machinability

CHARACTERISTICS OF PEI

  • Operation temperature: -70 °C to +180 °C (+200 °C)

  • Tensile strength: 48 (142) MPa

  • Sliding speed: 200 m/min

  • Fatigue: tensile fatigue strength at 20 °C
    10^6 stress cycles, 1 Hz = 33 MPa

  • Resistance to UV radiation

  • Gamma-radiation: Absorbed dose limited to 9000 kGy

  • Water absorption: max. 0,6 %
    dimensional changes: 0,25 %

  • Fire behavior: oxygen index (LOI): 47 %
    classification: V-0 (UL94), low flue gas emission

ADVANTAGES OF PEI

General chemical resistance of PLASTMASS™ PEI

  • PLASTMASS ™ PEI is resistant to alcohols, fuel for motor vehicles and aircraft, lubricants, cleaning

  • Resistant to weak acids and alkalis (PH-value <9),

  • Resistant to salt solutions, ether, hydrolysis of hot water and steam

  • Resistant to UV radiation

PLASTMASS™ PEI advantages compared with standard PEEK

  • With a toughness comparable to PEEK, PLASTMASS ™ PEI has a much higher final elongation

  • PV-value to 300%

  • All PLASTMASS™ PEI types have a better dimensional stability

  • PLASTMASS™ PEI only loses its rigidity at temperatures that are 50 °C above the maximum temperature load of PEEK

  • Higher wear resistance and impact toughness

PLASTMASS™ PEI advantages compared with bronze

  • Large, pre-producible stocks with PEI make it possible to minimize costs and time for material processing.

  • The low coefficient of friction and improved sliding properties increase the service life of the finished part and ensure less maintenance on machines

  • PLASTMASS™ PEI does not require shrinking due to its elastic properties

  • Our plastic can compensate for geometric errors due to its elasticity

  • It distributes the selective force influences perfectly across the entire finished part

  • Works without lubrication - a failure of the lubrication system does not lead to an emergency situation and a failure of the machine

  • Shock and vibration resistance

  • Low noise characteristics of the sliding parts

  • High positioning accuracy and smooth movement with low feed

  • Works in a dirty environment - PLASTMASS™ PEI has the ability to absorb abrasive foreign particles or impurities due to its elastic surface. As a result, no protruding particles remain on the sliding surface and do not cause abrasive wear.
