Product Properties Sheet Click here to download the Product Properties for Duratron XP (CM) in PDF format. Manufacturer Quadrant Product Catagories High Performance 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

Duratron XP the first real alternative to traditional polyimide shapes, was developed for use in extreme applications like high performance values, electronic devices and semiconductor manufacturing process equipment. Unreinforced Duratron® XP is bright yellow in color and is easy to machine. No special tools or procedures are required.A high purity polyimide, Duratron® XP contains less than 1 ppm of metallic impurities as measured using the ICP-MS test standard. This purity is comparable to other commercially available polyimide shapes. As a result, Duratron® XP is ideal for use in high -energy gas plasma etch and strip processes. Duratron® XP is resistant to most gas plasma formulations used in semiconductor processing and meets or exceeds the performance of other polyimide shapes.

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).
