Description
Detailed Introduction:
This composite material offers an excellent balance of mechanical durability and electrical performance. The aramid paper provides strong tensile strength and tear resistance, while the polyimide film delivers outstanding thermal endurance and dielectric properties. The smooth surface makes it easy to work with in automated manufacturing processes, particularly for coil insertion and winding operations.
AHA paper meets GB/T5591.3-2008 standards and serves as a practical alternative to traditional NHN insulation paper. It maintains stable performance under H-class temperature conditions and withstands the mechanical stresses of modern production equipment.

Common Questions
What temperature can AHA paper handle? It’s rated for continuous operation at 180°C, which corresponds to insulation Class H. This makes it suitable for high-performance motors and transformers that generate significant heat during operation.
Does it meet industry standards? Yes, AHA composite paper complies with GB/T5591.3-2008, the Chinese national standard for flexible composite insulation materials. It matches the performance characteristics of NHN insulation paper.
Can I get custom sizes? Absolutely. While the standard width is 1000mm, we can customize the width, thickness, and form factor to match your specific requirements. The paper is available in rolls for continuous production or pre-cut sheets and strips for specific applications.
Will the layers separate during use? No. The adhesion is tested at 200°C for 10 minutes without any layering, foaming, or glue flow. This ensures the composite structure remains intact even under demanding thermal conditions.
What’s the difference between longitudinal and horizontal properties? The material shows different mechanical properties depending on direction. Longitudinal strength is typically higher, which matters for applications where the paper experiences directional stress. We can help you determine the best orientation for your specific use case.
How should I store it? Store in a dry environment away from direct sunlight. The material has a shelf life of 12 months when stored properly.
Why Choose AHA Composite Paper
The combination of aramid and polyimide creates a material that’s both strong and heat-resistant. Unlike single-layer materials, this composite structure provides redundancy—if the outer aramid layer experiences wear, the polyimide core maintains electrical insulation. The three-layer design also improves tear resistance compared to thinner single-layer alternatives.
For manufacturers running automated production lines, the material’s smooth finish and consistent thickness reduce downtime from coil insertion problems. The paper feeds cleanly through equipment and maintains its shape during winding operations.
