Product EL 25

Thermal Class: 155 C

EL 25 is THEIC modified polyester enamel, with excellent performance, which can meet the strict demand on pinhole resistance test after elongation, rubbing and bending. It has good adherence property and remarkable levelling property that cause excellent appearance performance. It is suitable for single coating of the wire or as base coating of composite wire enamelling. If overcoated with polyesterimide, such as EL 88, the wire can meet with the requirement of IEC standard, class 180.

It is suitable for 0.04mm above different diameter wires. It is suitable for high speed machine or traditional multi-line machine, for vertical or horizontal ovens, for dies and felts application.
