Overview
Polyurethane Wire Enamels
UBL Polyurethane wire enamels are the preferred choice where direct solderability without stripping is required. Class 130 thermal performance combined with outstanding solderable film characteristics make these enamels ideal for relay coils, solenoids, fine motor windings, and any application where direct tin soldering of the coil ends is needed.
Thermal Class 130 (E)
Low to medium viscosity — solderable
Product Range
Available Grades
| Product Code | Thermal Class | Wire Range | Description |
|---|---|---|---|
| UB 1340-35 | Class 130 (E) | 0.05–1.0 mm | Standard polyurethane enamel with excellent solderable film; suitable for relay coils, fine motor windings and solenoids. |
| UB 1380 M1 | Class 130 (E) | 0.05–1.0 mm | Modified polyurethane enamel with improved thermal stability; enhanced mechanical properties for compact coil designs. |
| UB 240 | Class 130 (E) | 0.05–0.6 mm | Fine wire polyurethane enamel; excellent flexibility and film adhesion; direct solderable for electronics manufacturing. |
