SynTherm® – Insulating Materials

SynTherm® AP/80

SynTherm® AP/80 is a flexible 2-layer insulation made of polyester film with calandered aramid paper overlay.

Attributes

The proven dielectric properties of the polyester film and the excellent mechanical and thermal properties of the outer aramid paper layers result in a high performance insulating material. The ability of the outer layers to absorb impregnants results in exceptional bonding between all winding components.

Application

SynTherm® AP/80 is a cost-effective insulating material used in electric motors as slot insulation, phase insulation and wedges.
SynTherm® AP/80 is used as core, interlayer und final insulation for transformers.

Standards
  • Suitable for class F (155 °C) systems.
  • UL approved e.g. E247773
  • RoHS compliant according to 2011/65/EU
