Nitrile Outsole High heat protection

Nitrile Outsole

With heat resistance to 300°C, safety boots with Steel Blue’s Nitrile Outsole are great for working in very hot conditions (such as remote mine sites or on asphalt and steel plates) or situations where the sole of your work boots may come into contact with hot objects (welding).

The Nitrile Outsole is made from a type of higher heat resistant rubber and forms the outer layer of your work boots. At these high temperatures, there’s a 60-second threshold before it reaches melting point.

With superior resistance to abrasion and excellent tear strength, the slip resistant capabilities of Steel Blue’s Nitrile Outsole actually improves with wear. It’s also highly resistant to oil, mild acids and alkalis.

As if that wasn’t enough, the Nitrile Outsole helps reduce the build-up of excess static electricity and is chemical resistant.

All Steel Blue safety boots featuring our Nitrile Outsole comply with:

  • Australian and New Zealand Safety Footwear Standard AS/NZS 2210.3
  • International and European Safety Footwear Certification EN ISO 20345
  • American Safety Footwear Certification ASTM F2413

TPU Outsole The all-rounder

TPU Outsole

Our Thermoplastic Urethane (TPU) Outsole is the all-rounder, suiting most work environments.

The main difference from the Nitrile Outsole is that the TPU Outsole is more lightweight and is heat resistant to 130ºC.

Most of our work boots come standard with a TPU Outsole. It’s very durable, providing a high tolerance against cuts, abrasion, splitting and cracking, as well as a high resistance to most oils and chemicals. The TPU Outsole also provides slip resistance for uneven and slippery surfaces.

All Steel Blue safety boots featuring our TPU Outsole comply with:

  • Australian and New Zealand Safety Footwear Standard AS/NZS 2210.3
  • International and European Safety Footwear Certification EN ISO 20345
  • American Safety Footwear Certification ASTM F2413

If you don’t need extreme heat protection, this is the lightweight Outsole you need for your work boots.
