Flame retardant, perfectly hydrophobic additive for HFFR applications

In many cases, ATH/MDH fillers are the best choice to meet the standardized requirements for HFFR cable compounds. To perfectly embed the filler particles into the polymer matrix, SICO has developed an innovative additive that revolutionizes mechanical properties and LOI (limited oxigen index) of your product.

Economic efficiency through the replacement of expensive transparent materials

The addition of nucleating agents improves the optical and mechanical properties of polypropylene. The result: crystal clear PP with high stiffness and high impact strength. It is also suitable for food contact or odour sensitive applications. On the one hand, it makes it possible to dispense with cost-intensive materials such as PET, ABS and PS; on the other hand, it shortens cycle times and increases productivity. For these reasons, the nucleating agents are an excellent additive, which is already used by leading manufacturers in Europe.

Fields of application:

PP Masterbatches & Compounds for:

  • Transparent packaging (e.g. food packaging)
  • Injection Moulding
  • Extrusion blow moulding
  • Sheet extrusion
  • Increased gloss and transparency
  • Increased gloss and transparency


The aim is to simply replace costly materials such as PET, ABS or PS with PP by adding nucleating agents to increase economic efficiency.


Recommended dosage: 0.16 – 0.25%, dry mix for at least 5 minutes (speed at 1000rpm) to ensure uniform distribution.

Your advantages

Nucleating agents offer the following advantages:

  • Fast crystallisation, increased re-crystallisation temperature
  • Reduced cycle time and increased productivity
  • High degree of crystallinity, smaller spherulites
  • Improved stiffness and impact strength
  • Increased gloss and transparency
  • Approved for food contact
  • Easy processing


Cost-effectiveness can be improved by simply replacing expensive materials such as PET, ABS and PS with PP. This optimisation is possible thanks to nucleating agents.
