Welcome to Imerys Performance Minerals


Biopolymers Imerys minerals boost the performance of bioplastics for durable applications

Imerys minerals are 100% natural and inherently biocompatible making them the ideal agents for boosting the mechanical properties of biopolymers or ‘green’ plastics, allowing them to be used in demanding biopolymer applications such as durable packaging, automotive parts and electrical applications. 

Rigid bioplastics

Biopolymer reinforcement filler

Imerys minerals make ideal reinforcement fillers in rigid bioplastics such as polylactic acid (PLA) and polyhydroxyalkanoate (PHA).

Imerys minerals: 

  • Increase biopolymer stiffness 
  • Improve biopolymer dimensional stability, reducing shrinkage and thermal expansion
  • Increase heat deflection temperature
  • Improve barrier properties
  • Are food contact approved
  • Lower the carbon footprint of the final product

For rigid plastics, we particularly recommend:

Biopolymer nucleating agents

Imerys talcs such as our CrysTalc® range are ideal nucleating agents for bioplastics which speed up PLA crystallization, reduce molding time and production costs.

Biopolymer films

Our Mistroblock® product is ideal for achieving exactly the right balance between antiblocking performance and optical and mechanical properties in bioplastic films.

Foamed biopolymers

Micro-lamellar Mistrocell® is an outstanding nucleating agent for foamed bioplastic composites.

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.
