Polyonics - Innovative label and tape materials for Harsh Environments 

High Temperature Label and Tag Materials for Metal Manufacturing Factories and Foundries

The Polyonics® HIGHdegree high temperature hot metal label and tag materials are specially engineered to withstand the punishing temperatures and extreme heat environments 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 - Extreme High Temperature Tolerant, Hot Metal Labels and Tags.

The HIGHdegree high temperature resistant label and tag line is rated up to 600 °C. Labels and tags can be applied directly to, or hung from coils, rolls, bars, sheets, rebar, tubes, wire bundles, etc. as these hot metals leave their furnaces. But what really makes these high temperature hot metal label and tags rate so highly is the superior durability and quality we bake into every label and tag.

Our HIGHDegree labels and tags offer superior performance through extreme heat conditions to enable 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. The durability and superior performance of these hot metal labels in extreme environments make them suitable for applications involving hot surfaces, furnaces, industrial ovens, and other high-temperature environments.


HIGHdegree Labels

Polyonics HIGHdegree thermal transfer printed polyimide and aluminum bar code label materials for hot metals 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

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


The hang tags also provide high tear resistances so there is no unintended removal during storage or delivery to further ensure inventory accountability.


High degrees of track and trace accuracy and confidence.

Make the move to automated systems and eliminate the health and safety risks that come with hot metals while delivering the track and trace accuracy your customers demand.
