Product Properties Sheet Click here to download the Product Properties for Duratron 150 PI in PDF format. Manufacturer Quadrant Product Catagories High Performance Polyimide

Record Breaking Wear Resistance To 575°F (300°C)
15% Graphite Filled, Bearing Grade, Compression Molded Polyimide

• Lowest wear rates and highest PV capability
  
• Lowest wear to mating surfaces
  
• Higher hardness and 13 lower thermal expansion than other polyimides
  
• Better chemical resistance than other polyimides
  
• Unfilled grade offers high purity levels

Duratron® is a fully imidized thermoset polyimide. Full imidization and encapsulation of graphite lubricants in wear grades, make Duratron® PI stronger than other polyimides and provide excellent wear characteristics. In our Tribological Test Laboratories, Duratron® 150 has consistently achieved much higher limiting pressure/velocity levels and substantially lower wear rates than any other product tested. Duratron® PI is synthesized differently than competitive polyimides resulting in:

• Improved chemical resistance
  
• Lower coefficient of thermal expansion
  
• Significantly better physical properties

Material Notes

Duratron is a fully imidized thermoset polyimide. Full imidization and encapsulation of graphite lubricants in wear grades make Duratron PI stronger than other polyimides and provide excellent wear characteristics. In Quadrant EPP's Tribological Test Laboratories, Duratron 150 and Duratron 400 have consistently achieved much higher limiting pressure/velocity levels and substantially lower wear rates than any other Quadrant-EPP product. Duratron PI is synthesized differently than competitive polyimides resulting in improved chemical resistance, lower coefficient of thermal expansion and significantly better physical properties.

Application

Severe service bushings - Oven rollers and bearings made of Duratron 400 polyimide can endure high compressive loads and require no lubrication. (Prior assembly: Rolling element bearings.)

Critical service bearings - A textile equipment manufacturer specifies only Duratron 150 polyimide for applications in which bearing failure would be catastrophic. (Prior assembly: Self-aligning rolling element bearings.)

Wand tips and wafer boat handling tools - The high temperature capability and purity of Duratron HP polyimide, make it well suited for applications in the clean room. (Prior materials:PPS, PEEK, Vespel PI)
