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
