Welcome to Imerys Performance Minerals

Wire and cable

Wire & 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.

For Low and Medium applications

Calcined kaolin not only imparts excellent insulation properties but also provides very smooth surface finish and excellent dimensional control, due to low die swell imparted by the mineral.

Calcined kaolins also provide very low permanent deformation providing the insulation layers to maintain original thickness without deformation during cables production.

Suggested products:

  • PoleStar 200R and Glomax LX impart excellent electrical insulation properties to low and medium voltage power cables. 
  • PoleStar 200R and Glomax LX have low moisture absorption properties that ensure that insulation properties are maintained under wet operating conditions.

 

 

For medium and high applications

Calcined kaolin not only imparts excellent insulation properties but also provides very smooth surface finish and excellent dimensional control, due to low die swell imparted by the mineral.

  • Polarite 503S also provides good insulating properties in other polymers including  EPDM and ethylene vinyl acetate copolymers.
  • Hydrite range
  • Polarite range 

 

Air Float Kaolin for use in cable insulations as a versatile function mineral filler. 

  • We recommend Mercap

 

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.

 

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