SynWrap – Wrapping Tapes SynTherm® YT510 Crepe

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

Our SynTherm® YT510 Crepe is available in two versions:
F and SF with slightly different behaviour.

The basic material SynTherm® YT510 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. Due to its polymer-structure, SynTherm® YT510 is also suitable for temperatures up to -190 °C.It has a high short-term dielectric strength. SynTherm® YT510 is compatible with all classes of common resins, varnishes, adhesives as well as transformer liquids, lubricants, and cooling agents. Common solvents may lead to slightly reversible moisture expansion. SynTherm® YT510 has low flammability (UL 94V-0) and very high resistance to beta and gamma radiation.
