Description of Desired Solution

A brand new compatibilizer additive for recycled polyolefins that improves miscibility, enhances the appearance of parts and sheets, improves mechanical and physical properties, in an easy-to-use format.


Detailed Solution Description

A new generation of polyolefin compatibilizer is coming and it is targeted to the needs of recyclers and converters. Gone are the concerns about brittleness or stiffness. This compatibilizer is more targeted than others to eliminate the concerns regarding modulus. A variant can also increase melt strength of PP, making it possible to go from injection molded inputs to extruded sheet outputs. The development is progressing from lab to pilot phase and here’s your chance to finish its design.

What’s In It For You?

  • Become a privileged partner for the final phase of the new compatibilizer development
  • Benefit from the possibility to adapt the compatibilizer to your own stringent needs
  • Seize the opportunity to be an early adopter of the new compatibilizer
  • Benefit from a competitive advantage by adopting a more efficient compatibilizer


Ideas for final applications where this new compatibilizer can bring significant value:

  • Thermoformed packaging articles (dunnage);
  • Injection molded articles (durables for household, outdoor, automotive, appliances, electronics);
  • Extruded film and sheet (rigid and flexible packaging, non-food) and many others!
