As electronic components continue to get smaller and the use of automated handling systems increases, the fixturing and handling can cause labels to soften and scratch.  Polyonics XF-731 (1 mil) and XF-732 (2 mil) labels feature durable topcoat chemistries that are abrasion resistant when directly contacted at elevated temperatures and chemically resistant to the highly active fluxes. 

Polyonics label materials for PCB and electronics manufacturing have been tested and approved by leading flux providers such as Alpha Metals and Kester, and cleaner providers including Kyzen and Zestron.
