Industrial motors are the workhorses of manufacturing, powering compressors, pumps, conveyor systems, and heavy machinery across virtually every industry. Reliable motor insulation materials must withstand continuous thermal stress, mechanical vibration, and chemical exposure — making motor insulation class selection a critical design decision for long-term reliability.

Sui On Insulating provides high-performance electric motor insulation materials — including Nomex® aramid papers and SOFLEX® composite laminates — to safeguard the stability and durability of industrial motors in high-load environments.

Our solutions cover the full range of electric motor winding insulation requirements, from slot insulation and layer insulation to interphase barriers, supporting Class F and Class H insulation systems. For applications requiring class F insulation for motor or higher, our SOFLEX® NHN and NMN composites deliver proven thermal endurance at 155°C and 180°C respectively.
