Choosing the Right Polyolefin Additive for Mold Release and Internal Lubrication
How Kemamide® Fatty Amides Improve Processing Efficiency and Part Quality
In polyolefin processing, selecting the right additive package can significantly impact melt flow, mold release, surface quality, and cycle time. Among the most widely used and trusted solutions are Kemamide® fatty amide additives, which provide a balanced combination of internal lubrication and controlled mold release in polyethylene and polypropylene systems.
This article explains how fatty amides work, when to use them, and how to choose the right option for your polyolefin formulation.

Why Mold Release and Internal Lubrication Matter in Polyolefins
During extrusion and injection molding, polyolefins are exposed to high shear and thermal stress, which can lead to the following:
- High melt viscosity and torque
- Poor flow and incomplete mold filling
- Part sticking or difficult demolding
- Surface defects and inconsistent finish
- Longer cycle times and reduced throughput
Oleochemical additives like Kemamide® improve internal lubrication and mold release properties without compromising the mechanical performance of the polymer.
The Difference Between Internal vs. External Lubrication
Internal Lubrication Additives
Internal lubricant additives reduce intermolecular friction within the polymer melt, improving chain mobility and melt flow.
Here are some of their performance benefits:
- Lower melt viscosity
- Reduced shear stress
- Improved filler and pigment dispersion
- More stable processing conditions
External Lubrication Additives
Mold release additives migrate in a controlled manner to the polymer–metal interface, reducing adhesion between the part and tooling.
Performance benefits include the following:
- Easier demolding
- Reduced part damage
- Cleaner mold surfaces
- Shorter cycle times
The most effective additives provide both functions in a controlled, predictable way.
Kemamide® fatty amides function as slip and lubrication additives that integrate into the polyolefin matrix while offering controlled surface activity. At processing temperatures, Kemamide® provides these benefits:
Kemamide® plastic additives are especially valuable in PP and PE compounding and molding applications. These benefits make Kemamide® a reliable choice for both high-speed polyolefin production and complex molded geometries.
