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

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

Effect of Crodamide™ additives on friction
![Page 8: 2012 Crodamide Customer Presentation](https://reader037.vdocuments.mx/reader037/viewer/2022102818/55cf9bc1550346d033a743db/html5/thumbnails/8.jpg)
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)

Medium slip in LDPE

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
