AMA composite paper
Product description
AMA composite materials
The soft composite material of polyester film and aramid fiber paper is made by bonding and compounding two sides of aramid fiber paper with polyester film. This product has a heat resistance grade of H, and has good flexibility, excellent mechanical strength, dielectric properties, tear resistance, and paint absorption ability. Suitable for slot to slot insulation of H-level motors and generators, as well as interlayer insulation of dry type transformers. Interval insulation, etc.
