Material Spotlight: B-727 Glossy White Thermal Transfer (THT) Printable Polyimide Label

The Challenge

Brady B-727 Material Liner Diagram

Barcode or alphanumeric identification that withstands extreme environments of printed circuit boards or related electronic components manufacturing. The labels must withstand:

  • Wave solder environments for circuit boards and electrical component pre-process labeling
  • Extreme wash protocol and cleaning chemicals
  • Auto apply equipment

The Solution

Our B-727 glossy white THT polyimide material is an ultra-durable label that was created for the printed circuit board manufacturing industry.

Key performance attributes:

Abrasion Resistance

Abrasion resistance

Tested using Taber Abraser equipment with CS-10 grinding wheels and weighted arms. The print is still legible after 100 cycles.

High heat resistance

High heat resistance

Resistance to 212°F (100°C). Labels were subjected to a range of temperatures for 1,000 hours with no visible effect, while label remains functional.

Low temperature resistance

Low temperature resistance

Labels subjected to -40°F and -94°F (-40°C and -70°C) for 1,000 hours with no visible effect, while label remains functional.


Adhesion capabilities

Adheres to stainless steel and epoxy PC board.

Regulatory and agency approvals:

UL Recognized

UL Recognized to UL969 Labeling and Marking Standard when printed with the Brady Series R6000 halogen-free ribbon

RoHS compliant

RoHS compliant to RoHS Directive 2011/65/EU

Dibutyl and dioctyl tin free
