Features & Benefits

Features and Benefits

In injection molding and extrusion, the following advantages are:

  • Improved mold release
  • Improved dimensional stability of the finished product
  • Reduction of post–shrinkage of the finished product
  • Prevention of stress cracking of the finished product
  • Improved mechanical properties (Increase of tensile strength and stiffness)

Applications & Uses

Plastics & Elastomers Processing Methods
  • BRUGGOLEN® P252 is a very effective crystallization accelerator for all thermoplastic polyesters, inducing a very fine and homogenous crystalline structure. 
  • 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.

The recommended level of addition of BRUGGOLEN® P252 is 0.2 – 0.5%, depending on the polymer and the desired properties of the finished parts.

Technical Details & Test Data

  • The addition to the polyester 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® P252 along with polyester granules will not lead to an optimum dispersion of the additive in the melt during injection molding.
  • However, to support the dispersion of BRUGGOLEN® P252 when making a dry-blend, it is recommended that our BRUGGOLEN® P60 as adhesive agent is used.
