Hezhen calcined kaolin good suspension high purity and fine particle size kaolin powder for papermaking plastic ceramic coating

Descrição do produto

In paper manufacturing, calcined kaolin acts as a premium filler and coating pigment, improving brightness, opacity, and printability. Its fine particle distribution (typically <2 μm) enhances sheet smoothness and ink retention while reducing raw material costs by extending fiber usage.

For plastics, the material’s low oil absorption and high aspect ratio boost mechanical strength, stiffness, and thermal stability. It also imparts a matte finish and UV resistance, ideal for packaging films, automotive components, and consumer goods.

In ceramics and coatings, calcined kaolin’s refractory properties and fine particle size enhance glaze adhesion, reduce shrinkage, and improve crack resistance. As a functional extender in paints, it increases scrub resistance, opacity, and sag resistance without compromising flow properties.

With its ability to balance performance and cost-efficiency, calcined kaolin remains indispensable for achieving superior quality in paper, plastics, and decorative/functional coatings.
