Nucleating Agents

nucleatingheader

Nucleating agents are used to improve processing speed, dimensional stability, and physical properties in molded or extruded products. In foamed products, they improve dimensional stability and density by helping to control the formation of gas cells in either gas injection or chemical foaming applications.


Advantages of Polyvel’s nucleating agent masterbatches are:

  • No interference with other additives in the compound
  • Dust-free, pelletized products, easy to mix or feed in a blend or via separate pellet feeders
  • No processing changes required
