1. Crodamide ™ Slip & Anti-block 2012 customer presentation

2. Contents Introduction What are Crodamide ™ slip & anti-block additives? How do Crodamide ™ additives work? The Crodamide ™ range Applications and performance data Further information

3. Introduction Polymer surfaces often exhibit high friction High friction can cause a number of difficulties in: Winding of film rolls Bag production Packaging operations Mold release Additives are required to reduce surface friction

4. What are Crodamide ™ slip & anti-block additives The Crodamide range includes a variety of slip & anti-block additives: Primary amides Secondary amides Secondary bis - amides They can be incorporated directly into the polymer during the extrusion proces Crodamides are migrating additives that move to the polymer surface on cooling Lower friction is achieved between contacting polymer surfaces from a solid lubricating layer on the surface

5. How do Crodamide ™ additives work?

6. Applications - slip This is the movement of a polymer surface against some other surface The interaction of surfaces can be polymer to polymer, polymer to metal or polymer to glass High slip relates to a low friction value Slip ( measured by CoF - Coefficient of Friction )

9. Applications - slip This is the movement of a polymer surface against some other surface The interaction of surfaces can be polymer to polymer, polymer to metal or polymer to glass High slip relates to a low friction value Slip ( measured by CoF - Coefficient of Friction )

10. High slip in LDPE

11. High slip in PP

12. Medium slip in LDPE

13. Applications – anti-block Slip and blocking are related phenomena both involving the interaction of surfaces Most Crodamides will modify the blocking performance in film to some extent Since Crodamides form layers at the surface, they generally do not affect the clarity of film Anti-blocking
