Performance Additives

Performance additives such as microspheres, aramid fibers and odorants bring unique properties to products and compounds, including maximizing product lifespan, high temperature performance, light weighting and volumetric cost reduction.

Performance additives offer a range of different properties that can be applied to many polymer compounds to achieve desired finished product performance. End use applications can range from highly technical compounds to every day products including:

  • Elastomers
  • Adhesives
  • Engineering plastics
  • Plastic coatings
  • Machine parts
