Struktol at K 2016: To Launch Processing Aid for Recycled Polypropylene

Published on 2016-08-19. Author : SpecialChem

STOW, Ohio -- Struktol has developed unique process additives for reclaimed/recycled plastics and for polymer compounds that contain recycled content. Struktol will highlight these materials at the K 2016 exhibition Oct. 19-26 in Düsseldorf, Germany at Hall 06/A23 which is being shared with European distributor, VELOX GmbH.

These products are useful in a variety of different resin systems from polyolefins to engineered plastics, offering greater processing efficiency and enhanced performance. They are targeted for compounds containing 100% recycled material or materials with varying levels of post-consumer or post-industrial recycled content.


For engineering plastics, Struktol offers multiple products that combine a compatibilizer with lubricants to create a combination product that aids in the incorporation of fillers (mineral or glass) with improved mixing and flow properties as well as mold release. These products result in better processing, improved surface quality, and in some cases, better physical properties.

Additives on Spotlight at K 2016:

  • STRUKTOL® TR 229 is for use in both polycarbonate (PC) and PC/acrylonitrile-butadiene-styrene (ABS) blends as well as nylon 6 and 6,6 compounds. It can be used in FDA-approved applications and is also ideal for use in recycled applications.
  • STRUKTOL® TR 219 for use in nylon 6 and 6,6 compounds. It has been found to be effective in polyester (PET and PBT) compounds, especially recycled or recyclate-containing applications or in cases where the polyester compound is contaminated with other plastics.
  • STRUKTOL® RP 38 is a new, multi-functional package that incorporates vis-breaking technology with lubricant and odor control.
  • STRUKTOL® RP 37 is designed to provide unmatched viscosity modification and lubrication in recycled PP compounds and resins that contain high levels of polyethylene contaminants.
  • STRUKTOL® RP 11 is a unique lubricant package that provides an unmatched combination of viscosity reduction and mold release characteristics for recycled PP resins and compounds.
  • STRUKTOL® RP 06 provides similar viscosity modification and mold release combined with low odor and volatiles that are ideal in automotive applications.
  • This series of products can be tailor-made to fit the requirements of the recycle compounder, resulting in a unique additive designed to fit the application.
  • STRUKTOL® RP 17, a combination lubricant and odor neutralizing mask, was originally designed for reducing/eliminating compounding and end-product odors in wood-filled plastic compounds.
  • RP 17 can be used in recycled applications as well as automotive interior compounds where neutral odor may be a requirement.
  • STRUKTOL® TR 052 is a compatibilizer and blending aid that is extremely beneficial for incorporation of regrind/recycled product in a wide range of polymers.
  • TR 052 has been shown to significantly improve the processability and performance of mixed recycled streams used when separation of the resins is not done prior.
  • The additive compatibilizes dissimilar polymer systems allowing for expanded use of these mixed recycled streams.
