UK clays

Our cost-effective hyper-platy clays from UK offer excellent printability, opacity and high loading when used in filling applications.

UK clays

Hyper-platy clays for controlled printability and optics

Our UK clays are premium hyper-platy clays mined and processed in Cornwall in South West England. Our UK clays present a large plate diameter and thin crystal dimension that can deliver unique value to a variety of paper and board grades.

Functional fillers

Our UK kaolin filler options are suitable for a wide range of papers, including newsprint, supercalendered, uncoated mechanical papers and SC magazine papers.

Our general purpose Intrafill™ grades confer a combination of brightness and particle size providing good optical and print properties and good retention characteristics. Benefits include reduced sheet porosity and improved printability while maintaining satisfactory optical performance. 

Intramax™ filler kaolins are designed to achieve maximum optical performance in SC magazine papers produced under acid pH conditions.


In LWC gravure papers, ultra-platy kaolins such as our Suprasmooth™ grades provide improved coating coverage delivering better smoothness and gloss and allowing papermakers to cover rougher base stock with less calendering. In the pre-coat, papermakers can use large kaolin plates combined with blocky pigments to create a structured coating that improves optical and physical coverage.

Suprasmooth helps optimise costs. By producing a rougher, bulkier base paper, paper and board producers can increase machine speeds and improve fibre yield. 

Using Suprasmooth kaolins in coating formulas also reduces the need for expensive opacifiers and binders.
