Duratron PI

Product Profile:

• Lowest wear rates and highest PV capability
• Lowest wear to mating surfaces
• Higher hardness and 1/3 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

Duratron XP Unreinforced Duratron XP polyimide is produced from a high purity resin with very low ionic impurities and outgassing rates. It is well suited for structural and electrical applications where maintaining purity or electrical insulation is critical.

Duratron 150 Duratron 150 polyimide contains 15% graphite lubricant. It offers the best combination of physical properties and toughness among lubricated polyimide grades.
