Slip or surface friction, expressed as Coefficient of Friction or CoF, measures the interaction between two polymer surfaces or between the polymer surface and processing equipment.
High friction can result in difficulties with the processing of thin film, winding of film rolls, bag production and packaging operations.
Slip additives are products which can be added to polymers to control friction. They are added directly into the polymer during the extrusion process and migrate to the surface as the polymer cools, allowing a solid lubricating layer to form.
Cargill provides a wide range of slip additives in many different physical forms and can offer guidance on the right additive and dosage level to ensure the controlled level of slip required for your application and needs.
Optislip™ – Slip
The Optislip range of amides can be incorporated directly into the polymer during the extrusion process. They work by migrating to the surface as the polymer cools forming a solid lubricating layer at the surface. This acts to lower the coefficient of friction (CoF) or adhesion between contacting polymer surfaces and the polymer and other materials.
As a specialty polymer additives company, achieving tailored slip performance via the optimization of product combinations has become one of our technical strengths. By understanding additives at the molecular level, Cargill offers a superior range of primary amides, secondary amides and secondary bis-amides with precisely controlled functionality.
Incroslip™ – the ultimate in high performance and stability
Incroslip™ additives are a market leading range of innovative, high stability solutions delivering slip, and other benefits to polyolefins even in the most challenging applications. Incroslip™ additives are manufactured using a proprietary process to ensure the highest level of stability. They can be used in many applications where high stability, long-term performance and excellent customer experience is desired.
Help prevent friction between products with slip additives
Incroslip™ SL is a specially developed, food approved additive with exceptional slip and stability properties.
It is patented market leading technology that delivers long lasting high slip along with superior color, oxidative stability and improved organoleptic properties.
Optislip™ OR (Oleamide) is an unsaturated primary amide additive in powder form which produces excellent slip performance in polyolefins.
Optislip™ OR amide quickly migrates to the surface of the polymer to form a thin lubricating layer. This reduces the coefficient of friction and prevents any unwanted adhesion.
Incroslip™ G is a specially developed, food approved additive with high slip, and high oxidative and color stability properties. It is particularly suited for use in automotive applications.
It is manufactured using proprietary technology which removes oxidatively unstable components and precursors that give rise to instability whilst retaining the components that provide slip and stability.
