Burgess

Burgess 30P is a flash-calcined clay with a median particle size, designed to enhance the electrical properties of PVC compounds. It offers low specific gravity and excellent color, making it an ideal choice for cost-effective formulations by reducing the pound-per-volume requirements. This material functions as a filler, compatible with Polyvinyl Chloride (PVC), and adds value through its superior color and lightweight nature.

Burgess 40 is a hydrous kaolin clay with a median particle size and medium brightness, specifically designed for use in trade sales coatings and adhesives. This material has an acidic pH and is known for its excellent dispersibility. It functions as an extender, filler, and pigment in various formulations. Its fine properties make it ideal for applications requiring high-quality dispersal and pigmentation, with a powder form that ensures ease of use in diverse industrial applications.

Burgess Icecap K® is a high-performance calcined kaolin used as an extender for TiO₂ in coatings requiring a high Hegman grind. Its low screen residue, achieved through agglomerate removal, makes it ideal for applications in wire and cable, molded and extruded rubber, and plastic products. It offers good electrical properties, low compression set, and low water absorption.

Burgess Optiwhite® is a premium flash-calcined extender for TiO₂ with excellent GE brightness, widely used in first-line interior/exterior flat or low-sheen water-based and alkyd paint systems. It provides outstanding whiteness retention, hiding, and film properties. With excellent dispersion and high hiding capabilities, it can be combined with ultrafine particle-size hydrous clays, such as NO. 28/NO. 98, to achieve a satin finish sheen in paints.

Burgess Iceberg® is a conventionally calcined medium particle size clay with 91-93 GE brightness. It is used as a TiO₂ extender in trade sales interior/exterior flat paints, a filler/extender in flexible PVC with aesthetic needs, EPDM wire and cable insulation compounds, pharmaceutical rubber, and polyurethane sealants. It offers advantages such as improved touch-up, opacity, whiteness, tint strength, easy dispersion, low moisture levels, and cost-effective replacement for carbon black.

Burgess Optiwhite P® is a flash-calcined clay used to extend TiO₂ in flat interior trade sales paints where maximum whiteness is not required. It offers good GE brightness, excellent opacity, flattening, and improved touch-up, scrub, and burnish resistance, with a slightly off-white color. It reduces raw material costs while maintaining opacity.

Burgess Thermo-glace+ is a white, powdery kaolin used primarily as a filler and extender in plastics and elastomers. It is compliant with TSCA (USA) regulations and classified within the kaolin chemical family.
