OP-8400 Spec 09

OP 8400 Spec 09 is a performance-improved derivative of the original OP 8400 gap pad. It is exceptionally soft and exhibits good thermal performance. It is compliant to RoHS standard while maintaining its
halogen-free status. These special features are benefited from the proprietary composition of metal oxide fillers in its binder matrix.

It is electrically non-conductive and naturally tacky. Additional adhesive is generally not required.

Features and Benefits

  • 2.5W/m-K thermal conductivity
  • Good compressibility
  • RoHS Compliant
  • Halogen-free
  • Naturally tacky
