Mercap Series

Versatile, high-value, functional mineral fillers for rubber compounds

All kaolin fillers share some common features because of the plate-like shape of their particles, which results in some stiffening of the rubber compound.

This gives much better extrusion and calendering properties (exhibiting low die swell and good dimensional stability) than can be obtained from other mineral fillers.

Surface-treated products like our Mercap™ 100 and Mercap™ 200 have proven themselves to be versatile, high-value, functional mineral fillers.

Used in rubber compounds, our Mercap product range improves:

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

Kaolin functions as an extender and also contribute beneficially to the physical properties of the rubber compound.

The Mercap Series is recommended for:

• Cable sheaths
• Hose
• Footwear
• Tyres
• Seals and gaskets
