Welcome to Imerys Performance Minerals

Wire and Cable

Wire and Cable Imerys minerals improve the flame retardant properties of wire and cable

Imerys minerals are excellent partial replacements for flame retardants in PE, EVA and APP wire & cable applications.

EVA wire & cable applications

Imerys talc’s hydrophobic and electrically neutral platelets make it an ideal partial replacement for MDH and ATH in EVA compounds for flame retardant (FR) applications, reducing compound costs.

Imerys talc:

  • limits gas emission and oxygen diffusion resulting in delayed combustion
  • creates a physical barrier effect limiting heat and mass transfer
  • promotes char formation
  • improves ash cohesion
  • reduces smoke and afterglow


We recommend our high aspect ratio Mistron HAR® talc for exceptional flame retardant (FR) performance in EVA systems.

APP halogen free systems

Imerys mica grades make cost-effective replacements for ammonium polyphosphate (APP) halogen-free flame retardants (FR) for polyolefins commonly used to meet UL94 VO requirements.

Imerys mica:

  • improves dielectric formation
  • boosts char formation
  • maintains mechanical properties

We recommend our Suzorite® mica products for APP flame retardant (FR) replacement.

PVC systems

Our Suzorite® mica product range is ideal for improving dielectric formation in PVC cables.

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.
