Suprex

Suprex™ Air-floated hard kaolin for superior mechanical properties

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

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

Used in rubber compounds, Suprex™ improves:

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

Suprex™ is suitable for the following compounds:

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

Suprex™ is recommended for:

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