Technical Data
Full specifications, dimensions, and packaging information
Printer Compatible
Works with both thermal transfer and laser printers. Supports single and double sided printing formats for complete wire marking flexibility.
Flame Retardant
Made from durable, flame retardant polyolefin compound — suitable for safety-critical wire marking in defense, aerospace and power installations.
Permanent Identification
Once shrunk, printed markings remain legible throughout the operational life of the installation. Resistant to abrasion, solvents and UV exposure.
Two Supply Formats
Available in continuous reels for flexible cutting or pre-cut ladder format for high-speed automated printing and application processes.
Yellow & White Standard
Standard yellow and white colours provide high contrast for printed text. Custom colours available on request for specific colour coding requirements.
RoHS Compliant
Fully compliant with RoHS environmental standards. ISO 9001:2015 quality management certification ensures consistent batch-to-batch quality.
