Suprex™

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
