NEMA C

NEMA C is a cotton fabric (general purpose medium weave) impregnated with phenolic resin. NEMA-C is commonly used to make gears, pulleys, rollers, and guides. NEMA C is a mechanical grade material and does not have electrical properties comparable to NEMA CE.

Phenolic resin was invented in 1907 Belgian-born American chemist Leo Hendrik Baekeland.  It was the first completely synthetic polymer to be used in commercial applications, widely known as Bakelite™. Phenolic resin has proved to be very versatile and continues to be developed for an ever larger variety of uses, from billiard balls to adhesives. 

Phenolic resin combined with cotton fabric (NEMA-C) has good mechanical properties and toughness, high impact strength and good wear resistance. NEMA C is easy to machine and operates with less noise than metal. In addition, NEMA-C is not as abrasive as fiberglass alternatives when used in wear applications.  NEMA C can be used in explosion-proof environments because it does not spark when struck.

NEMA C Advantages:

• Provides a higher level of mechanical strength than paper. Grade CE offers better electrical properties and a greater resistance to moisture.

NEMA C Applications:

• Gears

• Pinions

• Spacers
