A Cost Effective Alternative for Polyurethane Foams

Overview Ecomate Product Review Usage & Market Applications India Trials Considerations Ecomate’s Success & Availability Conclusions

What is ecomate®? A liquid blowing agent or a foam expansion agent An alternative blowing agent for rigid and flexible applications Cost competitive & economical Been in Commercial use for more than 10 years Meets regulatory standards as an alternative in PU foams

Regulatory US EPA SNAP Approved RoHS and WEEE Compliant GRAS Approved Non-Toxic VOC-Exempt Montreal & Kyoto Protocol Compliant 2004- EPA SNAP Approval: Granted VOC-Exempt status 2009-GRAS Approval

Properties & Comparison Well-suited blowing agent for PUR & PIR foams Similar to HCFC-141b Liquid at room temperature No special equipment needed when handling Non-ozone depleting and virtually zero GWP Properties ecomate® 141b Boiling Point °C 31.5 32 Gas Lambda Value @ 25°C 10.7 10 Molecular Weight 60 117 Specific Gravity 0.982 1.24 Flash Point -19°C ND LEL (ppm) 50,000 72,000 Ozone Depletion Potential 0.11 Global Warming Potential ~1 725 In one year alone, FSI customers reduced CO2 emissions by 549,817 mt. 3 times greater than the closest competitor.

Ecomate Trials- India FSI partnered with independent system houses January 2014 agreed to trial ecomate FSI supply base formulation(s) Must be present during trials Provided technical support

Qualification Testing 4 Base Formulations Modified formulations to achieve target reactivity and density Cream: 25-30 sec Gel: 150-180 sec Free Rise Density: 25-30 kg/m3 Lab Testing Viscosity Compressive Strength Dimensional Stability (Heat, Humid, and Freezer) Closed Cell K-factor Shelf-Life Stability

Formula 1 Formula 2 Formula 3 Formula 4

FSI In House Testing Formula 1 & Formula 4 were tested using high pressure equipment 1.22m x 2.44m Thickness: 50mm and 100 mm Equipment Settings

High Pressure Testing Results

India Demo Both Formula 1 and Formula 4 were given to 3 system houses Systems were made with locally available polyols Substitutions were made to the guideline formula Systems were optimized for reactions speed etc. Respective System houses chose - one or both formulas to trial at their end-users (panel foamers)

India Demo – continued 5 panel producers were chosen by the Independent systems houses Panels were shot though HP equipment Panels of various lengths and thickness were used Density was maintained as per the current (141b) system in use Equipment parameters were kept the same Equipment was calibrated based on the new system ratio

Royal Industries (Delhi) Formula 4 was tested in the lab Only No equipment was available to run the trial Lab Mold was used to simulate a panel production Reactivity and density was recorded. The lab made sample carried to FSI labs for evaluation

Royal Industries (Delhi) Foam Supplies Testing Results

Industrial Foams (Delhi) Trialed Formula 1 & Formula 4 Want to trial both formulas Reaction profile was faster – end user preference A few block molds were filled – used for flooring applications Blocks molds were filled at 36kg/m3, 38kg/m3 & 40kg/m3 Metal faced and PE film panels 5 panels total 50mm & 60mm thicknesses

Industrial Foams (Delhi) Industrial Foams Testing Results Measured thickness at various locations on the panel After 3 weeks, remeasaured the thickness at the same locations. No apparent shrinkage!!!

Jindal Mectec (Delhi) System House A tested Formula 1 and Formula 4 Formula 4 chosen to trial No changes made to guideline formula Metal faced and PE film panels made 6 Panels total Thicknesses of 40mm, 60mm, 80mm, 100mm, 120mm Various lengths and widths

India Trial Results Summary

India Trials Summary Formula 4 was the preferred system by all parties No changes were made to equipment, operation, or production Adhesion to all facings (steel, PE film, etc.) was excellent Foam Supplies addressed all concerns during trials Will give assistance where needed Successful trials!!!!

Considerations Not a Drop-in replacement for all systems Optimization is REQUIRED! Minimal Capital Expense Fractional compared to hydrocarbon technology Cost Efficient Environmentally Benign Meets Montreal Protocol Meets Kyoto Protocol Thermally Efficient Flash Point ecomate – pure form flammable -19⁰C flash point ecomate – polyol blend nonflammable >35⁰C flash point ecomate – mdi blend nonflammable >35⁰C flash point

Considerations ecomate is not a corrosive species ecomate stored and shipped in metal containers Potential issues arise from: Unoptimized system Improper use of equipment Plastic seal compatibility must be checked! PTFE & Kalrez seals recommended

Why is ecomate successful? Compatible with most PU raw materials Meets or exceeds energy standards Can process through standard and/or existing equipment No additional capital investment necessary Available worldwide

Why is ecomate successful? Compatible with most PU raw materials Meets or exceeds energy standards Can process through standard and/or existing equipment No additional capital investment necessary Available worldwide FSI customer exceeded Energy Star standards by 23.7% utilizing ecomate technology.

ecomate® Availability – Worldwide

Conclusions Environmentally safe More compatibilizing than other blowing agents Minimal to no change in equipment Successful in various applications Not a Drop-in replacement for all systems Optimization is recommended for success Increasing the functionality of polyol blend Changing the surfactant type and amount Not all polyols OR surfactants are created equal
