HANDLING: AN OVERVIEW
Forane® FBA 1233zd is
✓ Non-toxic.
✓ Non-flammable.
✓ Easily handled as a liquid.
✓ Compatible with a wide variety of materials.
✓ Little to no capital investment required to convert.
✓ Often can be used in existing blowing agent tanks. ✓ Contact your Arkema representative to evaluate storage in your existing tanks.
✓ Can be used with R141b and cyclopentane equipment with limited modifications
• Review Safety Data Sheet (SDS) to become familiar with properties.
• Protect cylinder and fittings from puncturing and denting.
• Close cylinder valves when not in use.
• Secure cylinders to prevent rolling.
• Blocks, cradles can be used.
• Especially important when moving cylinders with fork trucks.
• Forane® FBA 1233zd is a liquid with a boiling temperature of 19ºC.
• Store Forane® FBA 1233zd in a cool, well-ventilated area, away from direct sunlight.
• Store on elevated or concrete floors to avoid cylinder corrosion.

MATERIAL COMPATIBILITY✓ = Recommended per
Arkema Standard Test Method*
* Plastic, Elastomer Samples: Samples were introduced into a test tube filled with Forane® FBA 1233zd blowing agent. The tube was sealed and placed in a water bath kept at a temperature above the boiling point of Forane® FBA 1233zd blowing agent for 5 minutes, 24 hours, or 100 hours. At the end of each time period, the sample was removed and measured for dimensions and weight. The sample was then subjected to a tensile test.* Metal Samples were tested according to ASTM G31-72.

Charging Forane® FBA1233zd
OVERVIEW
• Forane® FBA 1233zd boils at around 19oC (66oF), so care should be taken to limit evaporation during blending.
• Use of closed system or cooled system is recommended.
• 1233zd is soluable in polyol, typically up to 30 wt.% or more. Details on next pages
• Blending options for Forane® FBA 1233zd are similar to current blowing agents and include:
• Polyol-side or Isocyanate-side
• Metered addition
• In-line Blending

BLEND INTO POLYOLS
10
• Forane® FBA 1233zd has good solubility with polyols.
• Forane® FBA 1233zd can be pre-blended into polyol, typically up to 30 wt. %
or more.
▪ Data on specific polyol solubility is available in the Forane® FBA 1233zd Technical
Profile brochure.

Foam Formulation
OVERVIEW
17
With suitable selection of components, Forane® FBA 1233zd formulations can provide improved thermal performance, lower environmental impact, and long shelf-stability.
Additive suppliers are continually developing additional products suited for HFO use, so additional options may be available.
Extending Shelf-life of 1233zd FormulationsShelf-life is typically not a concern for factory-produced foam. However, for applications where extended shelf-life is required, the Arkema Technical Service Team is happy to assist you.
Selection of key components to extend shelf-life include:1. Catalysts2. Surfactants3. Polyol Selection
➔ To summarize, with proper selection of commercially-available components, extended
shelf-life can be easily attained.
Foam Formulation
CATALYSTS SELECTION
• Catalysts can be selected to improve shelf-life while maintaining the required
reactivity.
• Catalysts manufacturers provide guidance on their solutions for HFO-based
formulations.
▪ Several new catalysts have been developed specifically for HFO’s by additive suppliers.
• Arkema has evaluated many different catalysts for several foam applications,
including spray, pour-in-place, and appliance.
▪ Achieved success achieved in extending the shelf-life across all applications.
▪ Details available from Arkema Technical Service.
▪ Publicly-available technical papers on this topic:
• Costa, J., B. Chen, L. Abbas, S. Seshadri, “Improved Shelf Stability of Rigid Polyurethane Premixes Using AFA-L1, a low GWP Blowing Agent”, Proceedings of Polyurethanes Conference 2012.
• Costa, J., B. Chen, L. Abbas, S. Seshadri, “Forane® 1233zd – Continued Improvement in Resin Shelf Stability with this Low GWP Liquid, Non-flammable Blowing Agent”, Proceedings of Polyurethanes Conference 2014.

In some instances, formulating with Forane® FBA 1233zd
and historical catalysts led to reduced shelf life of the
polyol blend.
