Forces: commercializing new molecule(s)

Environmental regulation or restriction . . . .

  • EU F-Gas Directive: restricts the use of materials with GWP > 150 in emissive applications
    • Restricts the use of HFC-134a in specific applications
    • EU one component foam industry regulation: 04 July 2008
    • EU novelty aerosol industry regulation: 04 July 2009
  • Kyoto Protocol: Developed countries reduce GHG emissions 5% (1990)
    • EU reduce GHG emissions by 8% (1990 levels)
    • Japan striving to meet Kyoto commitments
  • Industry concern with further GWP regulation
  • Taxation of raw materials basis GWP values
    • Economic impact on finished goods
  • Climate Change bills in U.S. Congress

montreal protocol calls for hcfc 141b phase out
Montreal Protocol calls for HCFC-141b phase out
  • Montreal Protocol on Substances that Deplete the Ozone Layer
  • Baseline average of 2009 and 2010
  • Freeze 2013
  • Reductions: 10%m : 2015 > 35% :2020 > 67.5% : 2025 > 2.5% per year reduction 2030 to 2040
  • Complete phase out 2040
  • HCFC-141b has been phased out in United States, Japan and Europe
    • HCFC transitioned the industries to environmentally improved materials
  • Global pressure may accelerate the phase out date in other countries
    • example: India and UAE, as well as others
  • HFC’s are utilised where key needs demanded are:
    • insulation performance, and energy efficiency of finished products (refrigerators)
    • non-flammability property
  • Hydrocarbons, and other non-HFC materials, while flammable, may be used:
    • where deficiencies in insulation performance and flammability can be tolerated
    • spray foam industry is particularly sensitive to flammability (application / equipment)

HCFC’s successfully phased out in many countries

blowing agent attributes
Blowing Agent Attributes
  • Phase out of ozone depleting substances: ODS
  • Global warming potential: climate change impact reduction
  • Ground level smog formation: limited contribution
  • Low order of toxicity – safety in manufacturing use and finished products
  • Non-flammable – safety in manufacturing use
  • Insulation performance / energy efficiency: low lambda or k-factor
  • Processing and equipment implications
    • Liquids: appliance (refrigerators); commercial refrigeration; spray foam; insulating panels
    • Gases: extruded polystyrene (thermoplastics); special applications
  • Compatible with formulations and processing equipment materials
    • Low conversion cost: equipment investment and reformulation
  • Economic valuation in use – translates into finished product economics
  • Commercially available on a global basis

Attributes support governments’ and industry’s preferences

transition strategy timeframe dependent
Transition Strategy: Timeframe Dependent
  • HFC-245fa: Commercially available today – a transition solution
    • Widely utilised in NA. Specific applications: EU / Japan / China
    • HFC/HCFC-141b blend technology: ‘reduced cost’ transition option
  • HBA-2: World-scale capacity target is mid-decade
    • Conversion to HFC-245fa ‘directly applicable’ to HBA-2

HFC-245fa: Low capital, medium term safe route to ODS management

blowing agent energy efficiency lambda
Blowing Agent Energy Efficiency (Lambda)
  • Lambda is the measure of heat transfer through a material in a given time and temperature
  • Lower lambda is better: significant energy efficiency driven by insulation characteristics
  • When compared to HCFC-141b insulation performance:
    • HFC-245fa is equal to slightly better
    • HBA-2 has shown improvement over HFC-245fa
    • HFC-245fa/HCFC-141b blends should exhibit similar insulation performance

Transitioning: HCFC-141b  HFC-245fa  HBA-2 maintains energy efficiency

capital investment hfc versus non hfc
Capital Investment: HFC versus non-HFC

Why are HFC-245fa and HBA-2 blowing agents low capital investment?

  • They are non-flammable  none to limited capital requirement
    • Low risk – technology, workplace safety, environmental
  • HCFC-141b PUR equipment  little to no equipment modifications required
  • Both are liquid blowing agents with moderate vapour pressure
    • May require storage vessel up-grade  low capital investment
  • HFC-245fa conversion from HCFC-141b in US: Cost ≈ Minor

Why are Non-HFC (hydrocarbon & methyl formate) blowing agents challenging?

  • Generally flammable  significant investment in flammability mitigation
    • Blending operations; foaming equipment; storage vessels
    • Consequences of miss-operations  inherent risk of fire / explosions
  • Factory emissions  probable ground level smog formation
  • Non-HFC PUR foams typically exhibit deficiency in insulation performance
  • Non-HFC conversion in US: Cost ≈ $500 K USD to $ 5 M+ USD

(refrigerator factory)

HBA-2 is a LOW capital investment, near ‘drop-in’ transition from HFC-245fa

operational cost implications
Operational Cost: Implications
  • HFC = lowest total cost path to high performance for regulatory compliance
  • Non-HFC solutions have inherent energy efficiency penalty
    • Cost to restore energy efficiency: panels – low cost; refrigerators – high cost
  • Non-HFC solutions exhibit deficiencies in density, dimensional stability, LTTR*

* LTTR: Long Term Thermal Resistance

Non-HFC PUR requires additional costs to achieve equal performance
