BASF introduces new additive solutions for mechanical recycling

BASF has launched IrgaCycle™, a new range of additive solutions to address the imminent needs in plastics recycling.

Recycled plastics often contain impurities and polymer contaminants that accelerate polymer degradation, which change the material properties. Consequently, recyclers and plastic converters are facing quality and performance issues while processing recycled polymeric material. Formulated additive packages improving the properties of these recycled plastics can be a solution for this challenge.

?The production of plastics from mechanical recycling is expected to almost triple by 2030, driven by improved technologies and regulation. This corresponds to a growth of around 10 percent per year,” says Dr. Thomas Kloster, President of BASF’s Performance Chemicals division. ?With IrgaCycle we are expanding our existing portfolio step by step by specific solutions for recycling to support the circular economy goals for plastics.”

The new IrgaCycle range includes additive solutions that can help increase the percentage of recycled content in several end-use applications such as packaging, automotive & mobility, and building and construction. These solutions address specific quality issues associated with recycled resins, such as limited processability, poor long-term thermal stability and insufficient protection from outdoor weathering. At launch, the product line includes a range of different additive formulations, with more to follow in the future.

  • IrgaCycle PS 030 G enhances long-term thermal stability in rigid applications, mainly for recycled HDPE, polyolefins and mixed polymers.
  • IrgaCycle PS 031 G improves processing and long-term thermal stability of recycled LDPE and LLDPE for incorporation into films and related flexible packaging applications.
  • IrgaCycle PS 032 G provides processing stability and long-term thermal protection for recycled PP and polyolefin blends containing impurities.
  • IrgaCycle UV 033 DD combines weathering stability with enhanced thermal and processing stability for reclaimed HDPE and PP blends for re-use in outdoor goods.
  • IrgaCycle XT 034 DD rejuvenates processing, long-term heat stability and helps neutralize impurities of the “first life” of the plastic, and with this improves mechanical properties of polyolefin recyclates.
A specific advantage of these blends lies in their ready-to-use product forms, which are easy to apply in the recycling steps. The granulated non-dusting product form ensures safe and easy dosage during converting or compounding of reclaimed material.

The IrgaCycle range is offered as part of the VALERAS portfolio.
