SynTherm® – Insulating Materials SynTherm® YT564 (metastar® YT564)
SynTherm® YT564 is a synthetic electro-insulation paper consisting of a calandered, aromatic polyamide fibride flock composition, good glue affinity and composite capacity.
SynTherm® YT564 is a class H (180 °C) insulating material. Temperatures below 200 °C only slightly influence its electrical properties. The good mechanical properties can be extrapolated to significantly higher temperatures. SynTherm® YT564 is also suitable for use at temperatures to -190 °C due to its polymer structure. It hs a high short-term dielectric strength. SynTherm® YT564 is compatible with all classes of common resins, varnishes, adhesives as well as transformer liquids, lubricants, and cooling agents. Common solvents may lead to slight reversible moisture expansion. SynTherm® YT564 has low flammability (UL 94V-0) and very high resistance to beta and gamma radiation.
Application
SynTherm® YT564 is suitable for compositing with polyester film and the polyimide film F- and H-class laminates.
SynTherm® YT564 is also used for wrapping copper or aluminium conductors.
