ESD Control Material

Krefine
Advanced Static Dissipative Material for ESD Control Based on Kureha's
Unique Special Carbon.

Krefine has been developed with Kreha's unique carbon materials and original compounding technology. Krefine is able to overcome the problems associated with conventional Electrical Conductive Polymer Composites in the ESD sensitive environments and other fields.

Key Features
• Homogenous surface and volume resistivity.
• Ability to control respective resistivities within 10 to the first power in the range of 10E6-10E12 ohms/sq
• Low metal contamination.
• Low out-gassing
