Hard kaolin to improve mechanical properties in rubber  

  • Superior modulus
  • Excellent green strength
  • Improved tear and abrasion resistance
  • Enhanced processability

Our Suprex range is air-floated hard kaolin designed to improve the mechanical properties of EDPM, SBR and silicone rubber in a broad array of end-use applications.

Used in rubber compounds, the Suprex range improves:

  • Modulus
  • Tensile strength
  • Tear resistance
  • Abrasion resistance
  • Green strength
  • Processability
  • Cured stiffness

Our Suprex range is suitable for the following compounds:

  • SBR: improves tensile strength and wear and tear properties
  • Natural rubber: can be used at very high loading in natural rubber applications without affecting processability
  • Polychloroprene: provides outstanding tear resistance at high loading
  • Butyl rubber: greatly improves tear resistance

The Imerys Suprex range is recommended for:

  • Automotive hoses
  • Cable sheathing
  • Shoe soles
  • Hydraulic and industrial hoses
