AMA Composite Insulation Material is a flexible laminate with a thermal class of F or above. It is constructed by bonding a central layer of polyester film with aramid paper on both sides using a Class H adhesive. This structure provides an excellent balance of electrical insulation performance, mechanical strength, and thermal resistance.
The aramid paper used in AMA exhibits properties similar to Nomex® 464, offering high dielectric strength, good thermal stability, and reliable durability in demanding electrical applications.

AMA Composite material Properties

High Thermal Resistance: Depending on the grade of aramid paper used, the thermal class typically reaches Class F (155°C) or Class H (180°C), with some high-performance versions capable of withstanding up to 220°C for short periods.
Excellent Mechanical Properties: Combining the toughness of aramid paper with the tensile strength of the film, it offers superior tear resistance, fold endurance, and mechanical durability.
Stable Electrical Performance: It possesses high dielectric strength and insulation resistance, maintaining reliable electrical performance even in humid or high-temperature environments.
Great Processability: It is easy to slit, shape, and insert into slots, and it shows good compatibility with various insulating varnishes and resins.

Application of oil AMA Composite material

AMA composite insulation materials are primarily used in high-heat-resistant motors and transformers:
Motors: Slot insulation, phase-to-phase insulation, and liner/interturn insulation.
Transformers: Interlayer insulation for high and low-voltage windings, as well as wrapping for leads, ends, and coil exteriors.
Other Electrical Equipment: Insulation protection for electromagnetic coils, reactors, and electronic devices.
