BRUGGOLEN® H320 Features & Benefits

Features and Benefits
  • Excellent long-term protection of high-performance polyamides against embrittlement under maximum service temperature stress
  • Powerful protection against premature fatigue of mechanical properties under aggressive conditions caused by high temperatures, chemicals or weathering
  • Maintenance of surface gloss over a long period of time

Applications & Uses

  • BRUGGOLEN® H320 / BRUGGOLEN® H321 is a very strong antioxidant for polyamides
  • Note: The use of BRUGGOLEN® H320 / BRUGGOLEN® H321 leads to a characteristic green discoloration in polyamides. To avoid a dark brown or aubergine-colored discoloration refrained from using phosphites and sulfides.
  • For specific applications specially tailored BRUGGOLEN® - additives can be offered Engineering Polymers, as well as AP-NYLON® Caprolactam, the key component for Cast Polyamide 6.

Technical Details & Test Data

  • The addition to the polymer melt is best done by compounding on twin screw extrusion machines. Only this will lead to the desired optimum dispersion of the stabilizer in the compound. Dry blending of BRUGGOLEN® H320 along with polymer granules will not lead to an optimum dispersion of the additive in the melt during injection molding.
  • However, to support the dispersion of BRUGGOLEN® H320 when making a dry-blend, it is recommended that our BRUGGOLEN® P60 as adhesive agent is used.
