PLASTMASS™
PEI PLASTIC

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 PEEK. Our plastics are manufactured under high quality standards in our factory.

PLASTMASS™ PEI FAQ

What chemicals is PLASTMASS™ PEI (Polyetherimide) resistant to?

  • 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

What advantages does PLASTMASS™ PEI (Polyetherimide) have over PEEK?

  • Has a much higher final elongation

  • PV-value to 300%

  • Has a better dimensional stability

  • Only loses its rigidity at temperatures that are 50 °C above the maximum temperature of PEEK

  • Higher wear resistance and impact toughness

What advantages does PLASTMASS™ PEI (Polyetherimide) have over Bronze?

  • Lower material costs

  • Low coefficient of friction

  • Improved sliding properties

  • Increased lifetime

  • Does not require shrinking due to its elastic properties

  • Compensates geometric errors due to its elasticity

  • It distributes selective forces perfectly across the entire finished part

  • Works without extern lubrication

  • Shock and vibration resistance

  • Low noise characteristics of the sliding parts

  • High positioning accuracy

  • Smooth movement with low feed

  • Works in a dirty environment - has the ability to absorb abrasive foreign particles or impurities due to its elastic surface
