IrgaCycle™ XT 034 DD is an additive composition of stabilizers designed improve processing of highly contaminated recyclates.

This product is tailored for post-consumer and post-industrial polyolefin recyclates, which contain high amounts of incompatible contaminants. It is also well suited for PP/EPDM regrinds contaminated with paint residues (e.g. TPO bumper scrap) or Polycarbonate (PC)/polyester blends contaminated with paint residues (e.g. PC/PBT bumper scrap).

Addresses the following recycling challenges:

  • Depleted initial stabilizer packages
  • Presence of pre-oxidized polymer chains and low molecular weight oxidation products
  • Incompatibility issued caused by paint, ink, and adhesive residues, high filler and pigment loadings, etc.
  • Contamination with prooxidative species like metal ions
  • Insufficient shelf life

Depending on the residual stabilizer content, quality, and oxidation state of the recyclate material, IrgaCycle™ XT 034 DD is recommended in quantities from 0.5 to 2.0 %.

Features and Benefits:

  • Neutralizes residual paint particles, fillers, and carbon black to enable better processability and reduce undesired side reactions
  • Provides stable melt flow properties, enhanced long-term thermal stability for improved mechanical properties
  • Upgrades recyclates from automotive applications for reintegration into initial applications
  • Easy to handle product form allows easy doasing at various processing steps
  • Enhances processing and long-term stability of strongly contaminated recycled HDPE and PP fractions (source: highly filled, pigments, and coated materials such as automotive bumpers)
