VICTREX™ PEEK POLYMER ESD101

High performance thermoplastic material with tight electrostatic dissipative control and low outgassing. ESD performance not influenced by moulding conditions provided that recommended processing conditions are rigorously adhered to. Semi crystalline, granules for injection moulding, easy flow, colour black.

Applications in the semi-conductor industry were ESD control is essential while maintaining other performance requirements.

Important notes:
1) Processing conditions quoted in our datasheets are typical of those used in our processing laboratories

  • Data for mould shrinkage should be used for material comparison. Actual mould shrinkage values are highly dependent on part geometry, mould configuration, and processing conditions.
  • Mould shrinkage differs for along flow and across flow directions. “Along flow” direction is taken as the direction the molten material is travelling when it exits the gate and enters the mould.
  • Mould shrinkage is expressed as a percent change in dimension of a specimen in relation to mould dimensions.

2) Data are generated in accordance with prevailing national, international and internal standards, and should be used for material comparison. Actual property values are highly dependent on part geometry, mould configuration and processing conditions. Properties may also differ for along flow and across flow directions.
