Mistron® For film antiblocking, foam nucleation and improved mechanical properties and dimensional stability in plastics

Our Mistron® range of talc products are high purity, platy, microlamellar talcs that are used for film antiblocking, foam nucleation and for improving mechanical properties and dimensional stability in plastics.

Rigid plastics

Mistron® grades can be used as general purpose reinforcement agents in rigid plastics, where they provide:

  • Improved stiffness
  • Good HDT
  • Improved dimensional stability


Mistron® talc products for film antiblocking applications are engineered to provide:

  • Reduced blocking force
  • Improved dart drop strength and puncture resistance
  • High clarity and low haze in plastic films

Recommended grades for antiblocking:

  • Mistron® 400C (for high clarity and low haze)
  • Mistron® AB
  • Mistron® NT (surface treated)

Foam nucleation

Mistron® talc products can also be used for plastic foam nucleation where they:

  • Increase cell density
  • Reduce cell dimensions
  • Produce uniform cell distribution
  • Enhance properties of foamed plastics at constant density

Surface treated Mistron® ZSC is ideal for foam applications including in expanded polystyrene and foamed polyolefins.

We offer a full range of bespoke formulation and technical and process support services to help you match the right mineral grade to your application requirement.
