Opteon™ MZHeat Transfer Fluid

Technical Information
Introduction

Physical, Environmental, and Safety Properties

In response to a growing need for high performance

Propertyproducts with reduced environmental impact, Chemours
has commercialized a new heat transfer fluid, Opteon™ MZ.
Opteon™ MZ (HFO-1336mzz-Z) is a proprietary hydrofluoroolefin (HFO) specialty fluid with zero ozone depletion
potential (ODP) and very low global warming potential(GWP) of 2 (100-yr ITH). Opteon™ MZ provides excellent
physical properties and performance characteristics asa heat transfer fluid—clear, colorless, nonflammable,thermally stable, low toxicity, and environmental friendly.
The fluid has a boiling point of 33.4 °C (91.4 °F) and isUnits
