SynTherm® – Insulating Materials SynTherm® YT510 (metastar® YT510)

SynTherm® YT510 is a synthetic electro-insulation paper constructed of a calandered, aromatic polyamide fibride flock composition.

SynTherm® YT510 is a Class H (180 °C) insulating material. Temperatures below 200 °C only slightly influence its electrical properties. The excellent mechanical properties can be extrapolated at much higher temperatures. Due to the polymer structure, SynTherm® YT510 can also be used at temperatures as low as -190 °C.

It has a high short-time field intensity. SynTherm® YT510 is compatible with all common resin, varnish, adhesive classes, as well as transformer liquids, oils and refrigerants. Common solvents can result in easily reversible expansion. SynTherm® YT510 paper is flame resistant (UL 94V-0), moreover, it displays a very high level of beta and gamma-ray resistance.
