1/2" Wall Paper Phenolic Tubes

Paper Phenolic Tubes 1/2 Inch Wall

NEMA grades X, XX and XXX are composed of a paper base impregnated with a phenolic resin binder. These grades are among the lowest in cost and easiest to process. Phenolics are adequate for dry electrical applications with low mechanical stress. Paper phenolic generally does not compete with epoxies in resistance to moisture, humidity, mechanical strength, dimensional stability, shrinkage and retention of electrical properties in extreme environments. Still, paper phenolic meets the same electrical expectations under the same high temperatures as G10.

NEMA X certs to MIL-I-24768/12 PBM, IEC 60893-3 Type 4 PF CP 201
NEMA XX certs to MIL-I-24768/11 PBG, IEC 60893-3 Type 4 PF CP 203
NEMA XXX certs to MIL-I-24768/10 PBE, IEC 60893-3 Type 4 PF CP 201

Tubes are manufactured in random lengths between 30" and 36".
The pricing and minimum orders are based on the 36".

Tubes can also be produced in 42" to 48" random lengths for the same price per foot.
Measured lengths of 36"±1" and 48"±1" are also available (call for pricing)
