BPN’s pine bark tannin is a natural polyphenolic aqueous extract obtained from the bark of Pinus radiata. It is ideal for a wide range of applications where phenolic functionality or reactivity is required along with antioxidant, antimicrobial and UV absorbing properties.

Functionality and Applications

Pine bark tannin is suitable for a range of applications:

  • Functional additive in personal care/cosmetics applications offering high potency antioxidant, antimicrobial and UV absorbing attributes.
  • Phenolic substitute or co-reactant in adhesives and resins for plywood, particle board, MDF other wood or fibre products.
  • UV stabiliser, antioxidant, heat stabiliser or corrosion inhibitor in polymer coating formulations.
  • UV stabiliser, heat stabiliser, and antioxidant in polymer films and other plastic, foam or composite products or mouldings.
  • Precursor, co-reactant and multifunctional additive in a wide range of polymer and polymer foam products.
  • Absorbent or complexing agent for selected molecules or elements.
