Phenolic Plastics Engineering Specifications and Engineering Data

Phenolic Plastics are composites made from the combining of phenol, aldehyde and formaldehyde and filler materials. Phenolic materials are available in sheets, tubes, rods, blocks as well as specified shapes. Tradenames include: Bakelite, Novotext and Tufnol.

Typical filler materials used in Phenolic Plastic Compounds:

  • Wood Flour
  • Cotton
  • Paper Pulp
  • Chopped Canvas
  • Shredded cloth or fabric
  • Graphite
  • Carbon
  • Iron
  • Diatomaceous Silica
  • Powdered Mica

Typical NEMA Grade Laminate Materials:

  • X = Paper Phenolic Resin – Mechanical Grade
  • XP = Paper Phenolic Resin – Mechanical Grade – Hot Punch-able Grade
  • XPC = Paper Phenolic Resin – Mechanical Grade – Cold Punch-able Grade
  • XX = Paper Phenolic - General Purpose Grade
  • XXP = Paper Phenolic Resin – Mechanical Grade – Hot Punch-able
  • XXX = Paper Phenolic Resin – Electrical Grade
  • FR-1 = Fire Retardant – Paper Phenolic – Mechanical Grade – Hot Punch-able
  • FR-2 = Fire Retardant – Paper Phenolic – Electrical Grade – Cold Punch-able
  • FR-3 = Fire Retardant - Paper Epoxy – Electrical Grade
  • L = Cotton Phenolic Resin – Machine-able Grade
  • LE = Cotton Phenolic Resin – Electrical Grade
  • C = Cotton Phenolic Resin - Mechanical Grade
  • CE = Canvas Phenolic Resin - General Purpose Grade
  • FR-4, & FR-5 = Fire Retardant - Glass Epoxy Resin – Mechanical Grade
  • G-3 = Woven Glass - Phenolic Resin - General Purpose Grade
  • G-5 & G-9 = Woven Glass Melamine Resin - General Purpose Grade
  • G-7 = Woven Glass Silicone Resin – General Purpose Grade
  • G-10 = Woven Glass - Epoxy Resin – Electrical Grade (non-brominated)
  • G-11 = Woven Glass - Epoxy Resin – Electrical Grade
  • GPO-1 = Random Weave Glass - Polyester Resin – General Purpose Grade
  • GPO-2 = Random Weave Glass - Polyester – General Purpose Grade
  • GPO-3 = Random Weave Glass - Polyester – General Purpose Grade
