Ball Clay Range
Ball clays are also known as kaolinitic clays. Depending on the ore deposit, they can consist of as much as 80% platy kaolinite with the remaining component being mica and quartz. Ball clays can be soft or hard and can impart a high degree of hydraulic plasticity making them highly suitable for water-based adhesive where long suspension stability is desired.
Imerys grades, Barden and Franklin-R are widely used in an aqueous system consisting of acrylics binders or natural polymers. They are often used to impart shear-thinning viscosity and increase yield point for enhanced suspension stability. Ball clays are available as milled products with fine to ultrafine particle size.
Benefits of Ball clays are:
- High hydraulic plasticity
- Enhanced suspension stability
- Excellent reinforcement
- Potential barrier effect
- Potential to impart soundproofing
- Cost-effective reflectivity
Ball clays are used in:
- Acrylic systems
- Systems consisting of natural polymers such as starch and gums
Recommended Ball clays are:
- Franklin R
