MASTERBATCH-SLP4312/PP: A high-performance solution for the lubrication and easy release of polypropylene

An efficient answer to lubrication and productivity requirements

Godiplast GmbH offers MASTERBATCH-SLP4312/PP, a highly concentrated solution designed to enhance surface lubrication properties and optimize the extrusion speed of polypropylene.
Thanks to its innovative combination of additives, it also ensures safe and efficient demolding – even for complex parts or those with undercuts.

Application Areas

  • Films and sheets: uniform lubrication, excellent anti-blocking properties, smooth production

  • Profiles and sheets: improved dimensional stability and easier downstream processing

  • Multi-cavity injection molding: fast demolding and reduction of machine downtime

Technology and Formulation

  • Carrier: Polypropylene (PP), compatible with TPE-O

  • Active agents: synergy of erucamide and a special silicon dioxide derivative

  • Form: strand-cut granules

This unique formulation prevents parts from sticking to the mold while simultaneously forming an ultra-fine lubricating film on the surface – ensuring optimal operation and long-lasting anti-blocking performance.

Recommended Dosages

  • Film extrusion:

    • 0.5% → 500 ppm

    • 1.0% → 1000 ppm

    • 1.5% → 1500 ppm

  • Profiles / sheets: 0.5 – 2.0 %

  • Injection molding: 0.5 – 2.0 %

Note: The surface lubricating film may influence printing, adhesion, or welding. Preliminary testing is recommended.

Regulatory Compliance

The raw materials are listed in Regulation (EU) 10/2011 and can be used without restriction in applications involving food contact.
However, verification of overall migration on the final product remains necessary.
