E-8731B — 1 mil Black Antistatic Polyimide PCB Label (−40 to 300 °C)

Overview

E-8731B is a 1 mil matte black antistatic polyimide thermal-transfer label stock for functional labelling of highly specified electronic goods. The material is engineered to minimize the charge generated when the label is removed from the liner and to prevent a significant charge from building on the label surface after it is applied to a component or board — making it suitable for ESD-controlled assembly areas. Its polyimide facestock is dimensionally stable at high temperature, chemically resistant, and prints resist smearing even when the board and label are removed directly from a reflow or wave-solder environment.

Features

Specifications

• Apply to a clean, dry, contamination-free surface (isopropyl alcohol recommended) and use firm pressure. Preheating the labelled product can enhance print permanence under extreme solvent/abrasion exposure. Values are typical, not specifications — verify by application testing.

Applications

• PCB identification in ESD-protected areas
• Electronic component tracking
• Asset tracking
• Warranty labelling
• High-resolution printing
• Reflow or wave-soldering environments

Testing & Certifications

• RoHS compliant (2002/95/EC)
• Static-dissipative — surface resistance 10⁷–10¹¹ ohms/sq (EOS/ESD STM 11.11)
