Titanates and zirconates for plastics recycling

When recycling plastics, the proportion of polypropylene (PP) in polyethylene (PE) is limited to ~5%. As of today, mixtures of addition polymers (e.g. pure HDPE) and condensation polymers (e.g. nylon) are also incompatible. Compatibilisers are often used, but they often impair the mechanical properties of recycled plastics.

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

Goals

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

Application

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

Conclusion

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.
