Overview

Centering rings in high technology polymer

We complement our aluminum centering rings with a range manufactured from a high-tech polymer. These centering rings have a unique slotted design which prevents gas bursts. The CX2 polymer can be used at temperatures up to 120 °C and is unaffected by most common solvents. The material has an outgassing rate of 6.6 × 10-8 mbar l s-1cm-2 which makes it suitable for use in most vacuum systems, whilst giving additional benefits in terms of lower weight and cost.

Features and Benefits

The most useful characteristics of Nitrile 'O' rings for vacuum use are:
  • Low outgassing rate
  • Good deformation resistance (very resistant to set after compression)
  • High resistance to most oils.
Fluoroelastomer offers:
  • Very low outgassing rate (especially after baking)
  • Chemical stability at high temperatures up to 200 °C
  • High resistance to oils and many chemicals.
