Overview
Polyester Wire Enamels
UBL Polyester wire enamels are high-performance coating solutions for enamelling copper and aluminium conductors. Formulated for Class 130 and Class 155 thermal performance, they deliver chemical, mechanical, and electrical resistance across a wide processing range. All grades conform to RoHS Directive (2002/95/EC).
Thermal Class 130 / 155
Medium viscosity — felt & die wiping
