Nomex® T994 High Density Polyaramid Film (Polymetaphenylene isophthalamide)

Nomex® T994 High Density Polyaramid Film (Polymetaphenylene isophthalamide) draws on the densified Nomex 994 pressboard grade to provide robust, rigid dielectric plates where compressive strength and shape stability are paramount. The high-density structure resists creep and compression set, supporting spacers, clamping rings, and structural barriers that carry load in oil-filled or air-cooled equipment. In transformers, switchgear, and heavy drives, T994 holds dimensions during assembly, bake, and thermal cycling, helping keep clearances predictable under torque and vibration. Its relatively lower oil uptake versus softer grades maintains strength in liquid-filled systems, while the aramid backbone brings long-term thermal endurance typical of the Nomex family. Parts machine cleanly and finish smooth for reliable bonding and stacking. For teams targeting maximum stiffness and electrical integrity in compact envelopes, T994 provides a trusted path to durable, high-strength aramid insulation.
