2 ecomate ® advantages A LIQUID Physical Blowing Agent Patented: US, Brazil, China, Mexico, many others Thermally Efficient Insulation To Replace HCFCs, HFCs, HCs ENVIRONMENTALLY BENIGN – ZERO ODP, ZERO GWP, VOC Exempt [US EPA] Economically Advantageous – Use less! Excellent Solubility Low Volatility – Non-flammable Mixes Good Foam Properties Good Foam Flammability Resistance

14 Potential Challenges Flash Point Hydrolysis Toxicity Foam Properties

15 System Flash Point

16 HYDROLYSIS ESTER HYDROLYSIS PRODUCTS: – Formic Acid & Methanol YET Very Stable in Systems: 1 + yrs on shelf

17 Toxicity GRAS approval in 2009 (Generally Regarded as Safe) Legal opinion For home appliances No Toxicity Issues in Home Refrigerators

18 Use in Foams Rigid – Pour in Place – Spray Integral Skinned Flexible

19 Rigid Applications Refrigeration Moulded Roof Panels Pipe-in-Pipe Insulation Spray Foam

20 Foam Requirements – Domestic Appliances Good Gas Lambda values Good Foam Physicals GRAS [Generally Recognized As Safe] Side-by Side comparisons BEST – Due to Variations in Density, Flow, Cell Orientation Ice melt times Reverse Heat Flow analysis

21 Reverse Heat Flow – Our Study 7 cu ft Freezer Chests from same MFGR – Ecomate blown foam – 141b blown foam Two Ambient temps: 40°F & 0°F Heated by 1 Light Bulb at regulated voltage – 40°F, 0°F – Target Chest temperature = 90°F – Each Chest fed SAME VOLTAGE

27 SPRAY FOAM Like other foams – except: – Faster Reacting – Prolonged Shelf Stability > 3 mos. – 1:1 by volume – Uncontrolled Application Environment Two routes – PUR & PIR

28 SPRAY FOAM Blended polyols – Ester - Cost & Fire Properties – Amine - Reactivity & Drum Stability – Mannich - Adhesion & Drum Stability – Sucrose - Strength & Char What is the Best Combination ?

29 D-Optimal Mixture DESIGN EXPERT 6.0 DMT ESTER, 184 Eqwt MANNICH, 178 Eqwt SUCROSE, 152 Eqwt AMINE, 94 Eqwt OPTIMIZED [ DESIGN EXPERT ] – ESTER 50 – MANNICH21 – SUCROSE29 – AMINE 0 Combination of cost, flame, and smoke 20 – 50 Parts 20 – 40 Parts 0 – 30 Parts 0 – 25 Parts

30 SPRAY FOAM GOOD PROPERTIES CLASS 1 & 2 FLAMMABILITY 3+ MOs STABILITY

31 Integral Skin

32 ecomate ® – best alternative to 141b Solvates all Raw Materials currently used BPt. just above ambient [like 141b] Permits good skin formation Allows fast demold times Environmentally Benign Economical – Mol Wt HALF of 141b US EPA SNAP Approved

33 Flexible Foams Molded & Slab Good Solubility Fine Cells Safer than MeCl 2, Acetone Non-VOC Excellent Hand Can use MDI

34 Toxic Effects Long Term Animal Studies - ACETONE – Kidney Damage – Liver Damage – Nerve Damage – Increased Birth Defects – Lowed Reproduction [Males] Long Term Animal Studies – MeCl 2 – Cancer of Lungs, Liver, Pancreas – Fetal Toxicity [Females]

35 Flexible Foams Molded & Slab ecomateAcetoneMeCl 2 Mol Wt B Pt, °C LEL, vol% UEL, vol% Heat of Vaporization, cal/g CARCINO GEN PEL, ppm TLV, ppm Ecomate Lower GWP Lower HtVap = Lower Dens Safer to Use – MeCl2 = Carcinogen – 2x higher LEL = SAFER – 5x higher PEL = SAFER – 1/5 lower TLV = SAFER No Baggage – Now or Future!

36 CONCLUSIONS SPRAY – GOOD PROPS, CLASS 1 & 2, 3+ MOs STABILITY POUR – EXCELLENT PROPS, HIGH FIRE RESISTANCE, EXCELLENT THERMAL EFFICIENCIES INTEGRAL SKIN – ecomate - a perfect fit solubility, ideal BPt, Lo MW, environmentally benign SLABSTOCK All the above Safer than Acetone, MeCl 2

37 ecomate ® advantages A True LIQUID Blowing Agent Good Solubility Low Volatility Good Foam Properties Good Flammability Resistance Cost Competitive BENIGN to ENVIRONMENT No Future Baggage!
