Arc Resistant Composite Electrical Insulation Materials
Materials engineered to remain an insulator, even after an arcing event.
Glass-Melamine Products
Many electrical devices are designed not to arc. But in others, the potential for an arc is not only real, it is the primary failure mode for the component or insulation.
Norplex-Micarta produces composites based on many different resin and reinforcement technologies. But in the case of arc resistance, melamine resin based materials outperform the other options.
Used in fuse tubes, arc barriers, and other locations where the surface voltage stress is very high, these materials are available as prepreg, sheets, tubes, and rods.

Prepreg:
NP509B
NP509B is a glass-melamine prepreg suitable for winding or press molding.
It is commonly used for fuse tubes, arc barriers, and specialty applications such as terminal block covers.
