Kaolin for thermal paper

We create chemistry that makes mines love reclamation

Whether filling your car's gas tank at the local station, receiving a bank statement or buying a ski lift ticket, thermal reactive paper is used to generate a printed receipt, statement, or copy. BASF thermal paper grades provide a high level of surface smoothness and wax absorption, which are highly desirable for producing a quality print. Because at BASF, we create chemistry for a sustainable future.

Leading the thermal paper market

Thermal papermakers worldwide recognize BASF's Ansilex® as a leader in the calcined kaolin market. From point-of-sale (POS) receipts to lottery tickets and labels, the applications for thermal paper continue to grow.

The precoat layer of the thermal paper is where kaolin is used, specifically to create a smooth printing surface and also to insulate the heat of the thermal printhead.

Meanwhile, our hydrous kaolin-based topcoats help to prevent head deposits on the thermal paper print heads.

Products & Families

 

Premium brightness calcined kaolin

Ansilex® 93 calcined kaolin has high brightness with fine particle size. The unique coating morphology (bulk and porosity) generated by Ansilex® 93 enhances aesthetics and printability. It is ideal for improving opacity, brightness, smoothness, ink receptivity, blister resistance, glueability, binder migration and printability. As a paper filler, Ansilex® 93 imparts cost-effective opacity and brightness in wood free and mechanical pulp furnishes.

Coarse Particle Size Delaminated Kaolin

ASP 809 is a coarse particle size delaminated coating kaolin. ASP 809 is produced from selected coarse particle size kaolins that are mechanically delaminated, which separates stacked kaolin booklets into individual platelets. Fractionation and beneficiation processes are employed to control particle size and brightness.
