Polyimides

The Protatherm® range of high temperature polyimide materials consist of six grades offering exceptional thermal properties and mechanical characteristics. These materials have been developed specifically for use in high temperature applications for container and pharmaceutical glass production, exhibiting the following properties:

  +   Maximum temperature range of 360-450°C
  +   Dimensional stability at elevated temperatures
  +   Extremely low thermal conductivity
  +   High wear resistance
  +   Excellent impact strength

Protatherm polyimides offer glass producers an excellent solution where the risk of thermal shock due to temperature differentials or the high conductivity of materials touching the glass can extract too much heat too quickly, causing cracks or other defects in the glass.

The physical properties of the above materials can vary, and values represented should be considered as typical. They are offered for guidance only, and should not be interpreted as any form of guarantee or specification.
