18. Spray Foam Overview
Spray foams are worst-case scenario from a safety and emissions perspective
ecomate systems have been proven safe to use by several third party agencies
No changes needed
Spray foams widely accepted to be worst case scenario from safety and emissions perspective. We have done intensive testing internally and externally.
Not once has there proven to be close to bean unsafe scenario.
It is safe to assume that if ecomate is safe in spray foam apps, that it will be safe for all other applications.

19. ecomate® Applications
Flexible Foams
Integral Skin Foams
Automotive
Furniture
Leisure/ Toys
Medicinal Applications
Flexible Molded Foams
Hypersoft Foams
HR Foams
Viscoelastic Foams
Slabstock Foams

Box foaming process

20. Integral Skin Polyurethane
What is an ISF
Elastomeric Polyurethane Foam
Solid Skin on Surface
Low Density Foam Core
Typical Skin Density >0.8g/cc
Typical Core Density <0.4g/cc
Applications -
Automobile Parts
Office Furniture Parts
Sporting Goods
Medical Equipment
Protective Equipment

21. Integral Skin Foams With ecomate one can achieve similar or
better Molding Characteristics as 141b based foams
This is achieved through –
Excellent solubility in raw materials
Perfectly suited Boiling Point - allows skinning without expensive cooling.
Benign effect on environment- no GWP, ODP, VOC
Lower Molecular Weight advantage over alternatives.

22. Integral Skin Foam – Structure
Densified Skin
ISF
Low Density Core mm

23. ISF Foaming Process Paint Mold Injection Mix Expansion and Cure Demold
The Foam expands & creates Pressure in the Mold
Ecomate® condenses in the Surface Layer causing Densification
A Skin is produced on the Surface
The Core Foam has a Lower Density
This Process requires a Volatile Blowing Agent – ecomate

24. CHOICE OF BLOWING AGENT
WHAT IS THE REQUIREMENT FOR PU FOAMS
NON REACTIVE - with Foam ingredients used
BOILING POINT – below or just above room temp
SOLUBILITY – in all raw materials
NON - SOLUBLE - to final Polymer Foam
ENVIRONMENTALLY - Benign
FLAMMABILITY - Non-flammable

25. PROPERTIES – PHYSICAL & ENVIRONMENTAL

26. 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 +70⁰C flash point
ecomate – mdi blend nonflammable +80⁰C flash point

27. 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

28. Is ecomate® - Flammable?
Pure ecomate is flammable
Ecomate blended systems are considered combustible just like 141b-blown systems
Why is this important?
ecomate® systems are safer to handle than flammables and Hydrocarbon/Pentane PU systems. In addition, systems made with ecomate have much lower shipping, handling & storage costs vs. Hydrocarbon/Pentane systems and other flammables.
Facilities equipped to handle 141b systems and/or isocyanates need little to no changes or upgrades. There is no need for large capital changes to facilities.
High Insurance premiums and costs associated with flammables and Hydrocarbon/Pentane PU systems are much lower for systems made with ecomate.

29. Is ecomate® Safe? YES Contributing factors
Chemical Nature
High Solubility
Low Volatility
Can be handled similar to HCFC-141b Systems
If adhering to current regulations and handling precautions for MDI ….user is covered and should have nothing to worry about.

Above & Beyond Requirements

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

31. ecomate® Availability – Worldwide

32. Conclusions Environmentally safe
More compatibilizing than other blowing agents
Minimal to no change in equipment
Ecomate spray foam (worst-case scenario) has been proven safe by multiple third party testing facilities
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
