Label and Tag Materials for Metal Manufacturing Factories and Foundries

The Polyonics® HIGHdegree label and tag materials are specially engineered to stand up to the punishing demands of metal manufacturing factories and foundries.

Reliability. To the extreme.

The Polyonics HIGHdegree portfolio of label and tag materials thrives on the extreme temperature ranges encountered throughout the metal manufacturing process so you can accurately control inventory.

From furnace through delivery of completed goods to customers, they can take the heat every step of the way.


Forged under fire.

The HIGHdegree line is rated up to 600 °C and labels can be applied directly to or tags hung from coils, rolls, bars, sheets, rebar, tubes, wire bundles, etc. as they leave their furnaces. But what really makes them rate is the superior durability and quality we bake into every label and tag.

Their extreme performance through extreme heat enables you to avoid the high expense of product recalls due to mislabeled or incorrectly labeled materials and unreadable barcodes – and the labor costs associated with manual labelling and tagging.


HIGHdegree Labels

Polyonics HIGHdegree thermal transfer printed polyimide and aluminum bar code label materials include unique, non-yellowing polymer or silicone print surfaces along with aggressive, high temp acrylic or ultra-high temperature silicone pressure sensitive adhesives (PSA).


Application of labels up to 1,112 °F (600 °C) with High strength permanent bond from - 40 °F to 1112 °F (40 °C to 600 °C).


HIGHdegree Tags

For applications up to 1202 F (650 C).

Polyonics 5 and 6 mil polyimide HIGHdegree tag materials are excellent alternatives to riveted plates, chalk or crayons for tracking hot metals in foundries.
