Electrical Properties

Cri-plastMP™ PFA Electrically Conductive Compounds are designed for real application use, not just datasheet properties.

Elongation

Do your electrically conductive products have an elongation specification? Do the raw materials used retain their conductivity at these elongation values … probably not. Cri-plastMP™ compounds retain their conductivity even at 150% elongation. Conventional carbon filled products do not.

Elevated Temperatures

Changes in Temperature are a fact of life. You design you materials to operate at elevated temperature, why wouldn’t you do the same for your static dissipative performance? Cri-plastMPTM compounds retain their conductivity even at 150 C. Conventional carbon filled products do not.

*Note: The Cri-plastMP was used as a masterbatch and letdown at low levels with carbon black. Cri-plastMP™ compounds exhibit very little change in resistivity, even at elevated temperatures.
