AMA Insulation Paper For Electric Motor

AMA insulation paper for electric motor is a cost-effective Class H composite insulation paper. It shares a similar three-layer aramid paper-film-aramid paper structure with NMN, but AMA uses domestic high-end Metastar™ aramid paper instead of imported Nomex paper, delivering performance close to NMN at approximately 30% lower cost. AMA serves as an ideal compromise solution for projects requiring Class H temperature resistance with budget constraints. The name AMA derives from its composition: A stands for aramid paper, M for Mylar polyester film, and another A for aramid paper. The intermediate Mylar film provides mechanical strength and breakdown voltage, while the two outer layers of aramid paper deliver temperature resistance and flame retardancy.

Last year, a transformer distributor from Indonesia contacted us with customers requiring Class H insulation paper but limited budgets, as NMN was too costly. We recommended AMA made with domestic Metastar™ aramid paper, which offers performance comparable to NMN at a 30% price reduction. The customer placed a 1-ton trial order and was highly satisfied after use, placing stable quarterly reorders thereafter. We baked AMA in a 180℃ oven for 72 hours, and its breakdown voltage only dropped from 11kV to 10.2kV, a decrease of less than 8%, against the industry standard maximum allowable decrease of 15%, meaning our performance far exceeds industry benchmarks. For distributors, AMA is an easy-to-promote product: when customers desire Class H performance but consider NMN overpriced, recommending AMA demonstrates your professionalism while helping them save costs.

• Slot insulation and interphase insulation of Class H motors
• Interlayer and inter-turn insulation of transformers
• Internal insulation of electrical equipment requiring flame retardancy
• Projects requiring Class H performance with budget limitations
• Cost-sensitive export markets including Southeast Asia and the Middle East

We are one of the early domestic manufacturers to achieve mass production of AMA composite paper. AMA production requires high-precision three-in-one composite machines for one-step three-layer lamination to ensure uniform bonding free of bubbles and wrinkles. Many small factories split the process into two separate lamination steps, resulting in bubbling and unstable insulation performance. Our three-in-one composite machine supports a maximum composite width of 1600mm with an annual production capacity of 1,000 tons. We also act as a processor for domestic high-end Metastar™ aramid paper with stable raw material supply channels to avoid order delays caused by raw material stockouts.

Our standard payment term is 30% advance payment with the remaining 70% balance settled before delivery. Customized products involving special specifications and raw materials require 50% advance payment and 50% balance before shipment. We accept RMB and USD settlement. Discounts are available for large-volume orders based on purchase quantity and cooperation cycle. We prioritize long-term partnerships with transparent and fair pricing, rejecting one-off profit-driven transactions.
