CYB — Graphite-Filled Phenolic

CYB graphite-filled phenolic is a wear-resistant plastic that offers self-lubrication features to help reduce wear. Atlas Fibre proudly manufactures this and a complete range of other phenolic laminates. Explore this material’s properties, benefits, and typical applications to discover its value for your company.

What Is Graphite-Filled Phenolic?

Graphite-filled phenolic combines a phenolic resin binder with a cotton canvas subsurface. During manufacturing, we introduce graphite to the material to deliver the extra lubrication.

Key properties* of CYB graphite-filled canvas phenolic include:

  • Specific gravity: 1.36
  • Maximum temperature: 125° Celsius (257° Fahrenheit)
  • Rockwell hardness on M scale: 105
  • Flexural strength — LW -A 0.125″: >17,000 pound-force per square inch (psi) [117 MegaPascal (MPa)]
  • Flexural strength — CW -A 0.125″: >16,000 psi (110 MPa)
  • Compressive strength, flat-wise: >39,000 psi (270 MPa)
  • Izod impact strength — LW: >1.6
  • Izod impact strength — CW: >1.4
  • Water absorption — .125″: < 1.6%
