The Biopolymer Landscape
What Are Biopolymers ?
Renewable Feedstock
Renewable, NOT compostable
Renewable AND compostable
• Bio-PE- Braskem • Bio-PET – (partially bio) • Nylon 11
• Ingeo • PHA • Thermoplastics Starchs
Non-Compostable
•Biopolymers are NOT based on Petrochemical “degradable additives” based •Biopolymerse do NOT use NOT compostable “oxo-degradable” additives • Conventional Plastics (Not Considered (e.g. PE, PP, PS, PET, •Biopolymers are NOT Bioplastics) PC, PVC,and etc) designedABS, to fragment ‘disappear’
Compostable
Petrochemical based AND compostable • PBS, PBAS, PBAT, PBAST, PCL, etc. Non-renewable (fossil) Feedstock 11

Amorphous vs. Crystalline Ingeo™
18
© 2013 NatureWorks LLC
Amorphous Ingeo • Transparent in appearance • Glass transition is approx. 55C (130F) • Regrind will be amorphous. – Susceptible to feeding problems during processing. – Screw sticking/screw wrap
• Requires lower drying temperatures – 50C (120 F).
19
© 2013 NatureWorks LLC
Crystalline Ingeo • A majority of our grades are supplied from our plant crystalline. • Pellets are opaque in appearance. • Crystallinity improves extrusion performance. – Due to higher melting point (around 165C/330F) – Eliminates screw sticking/screw wrap

Extrusion Set Up • General purpose screws work well. • Completely clean hoppers, filters, convey lines. – This is easily over looked and the major cause or poor quality sheet
• Purge high melt polymers (PET) with PS, PP, or PETG. (follow guide) • Polymer must be dried. • Regrind up to 40% can be used. – Higher levels require recrystallizing the flake or screw cooling 33
© 2013 NatureWorks LLC
Sheet Extrusion Optimizing • • • • • •
Three roll stack with high PLI, 600-800 (similar to PET) Sheet cannot contact middle roll prior to top roll. (very important) Run very small or no bank in nips. Adjust roll temps to just below polymer sticking. Die as close as possible to roll. Reverse profile for larger extruders.
34

Slitting • Rotary shear works the best. • Razors may work on thin sheet, highly modified sheet, or heated sheet. 35

Ingeo Innovations in Flexible Films
44
Š 2013 NatureWorks LLC
Flexible and Rigid Films • Flexible (Blown)
•
– Typical PE applications – Ingeo by itself is too rigid. – Must be modified with other polymers. – Requires a compounding step. – EcoVio (BASF) is the most common polymer used for blown film.
Rigid (Oriented) – Ingeo works well in this application. – Stressed induced crystallization allows for higher heat. – Film stays clear. – Requires biaxial orienting assets.
45
© 2013 NatureWorks LLC
Differences in Film Grades • 4032D – High crystallinity – Low shrink oriented films
• 4043D – Modest crystallinity – Higher shrinkage oriented films – Tamper bands, etc.
• 4060D – No crystallinity – Typically used for a heat seal layer – 46
© 2013 NatureWorks LLC
Some Applications Develop Heat Resistance • Due to crystallization • Gift Cards – Develop crystallinity during a press polish step
• CPLA Thermoforming – Similar to thermoforming CPET using a nucleant
• Oriented films – Develop crystallinity during orientation and maintain clarity
• Fibers – High process speeds and drawing crystallize the fibers

Increasing D-isomer level
•HP grades with very low D-isomer content will have significant impact on physical properties 48
© 2013 NatureWorks LLC
Comparing High L to Low D
3100D (High L) vs. 3001D (Low D) • Practical Tm peak is increased by 8°C from 164 to 172°C • Melting shoulder is increased by 15°C • Practical crystallinity is increased from about 45 to 55 J/g (48 to 59%) • Quiescent crystallization rate increase by 3-4x • Lower stress required for stress induced crystallization 49
© 2013 NatureWorks LLC
Injection molding results with High L pilot materials • NatureWorks internal lab studies show that formulations made with new High L pilot material vs. traditional Low D commercial material process with about half the required cycle time for high quality injection molding • Customer feedback confirms this finding, with High L pilot material at about 60% of the Low D cycle time at constant additive package • Optimal mold temperature is 80 to 120C, depending on the formulation • High L formulas have broader mold temperature windows, leading to more robust process parameters 50
© 2013 NatureWorks LLC
•
Advantages of expanded offering for the durable & semi-durable market Compounders can produce more competitive materials – Higher productivity during molding – Wider processing window – Simpler & more cost effective formulations
• Potential for higher bio-content in formulations • Higher modulus above Tg, higher HDT • Improved performance in extruded & thermoformed durable applications 51

“Did you know that if you convert just 500,000 medium sized deli containers to ones made with Ingeo™ the fossil energy savings is equivalent to 5,400 gallons of gasoline, and greenhouse gas savings are equivalent to driving a car over 122,000 miles?” ²
”
² These benefits are provided as an example and are based on the Ingeo™ eco-profile and available data on PET. Assumes replacement of a 30 gram PET deli container, with an equal weight Ingeo™ with no changes in the eco-footprint associated with the downstream processing from polymer to finished container.
