6Nucap 190W is a high brightness sulfur-functional silane treated kaolin used in white roofing membranes
and white sidewalls. In addition to faster mixing, Nucap 190W may allow the formulator to reduce theamount of added silane. The treatment aids dispersion in soft, low shear compounds such as stoppers,tubing, and printing blankets.

6Nucap 290W is a high brightness sulfur-functional silane treated kaolin with the highest level of surface
treatment to impart the best mechanical properties and water resistance. Silane treated clays mix infaster and may allow the formulator to reduce the amount of added silane. The treatment aids dispersion
in soft, low shear compounds.

Polyfil DL and Polyfil DLX have platy particles that reduce gas/vapor permeability and help improve gas
retention properties in rubber inner liners and other applications. In the delamination process, KaMin
processes kaolin particles (stacks of platelets, as they are found in nature) in special wet-grinding,
attrition mills. The clay stacks are reduced to thin kaolin platelets. This platy structure can also provide
modulus and hysteresis advantages for rubber articles such as seals, rollers, etc. due to this directional
reinforcement.

6Polyfil WC is an anhydrous silane-modified calcined kaolin clay used in wire and cable and otherthermoplastic applications. It is designed to reduce water vapor transmission, yields excellent wetand dry electrical properties, and also good long-term stability in EPR and cross-linked polyethylene.
Calcined clays impart low conductivity due to the elimination of bound water during the calcining process.
Compounds with calcined clays extrude smoothly and reduce stickiness in processing.

Polyfil ® WC 426

Fine

1.5169314; 256Polyfil WC-426 is an anhydrous silane-modified calcined kaolin clay designed to maximize compatibility
with surrounding polymers and to minimize absorption of interfacial moisture. Mechanical and electricalproperties of polymers such as EPR and cross-linked polyolefins are preserved even after long-term
exposure to a high-humidity environment. Calcined clays have low conductivity due to the elimination ofbound water during the calcined process. Compounds with calcined clays extrude smoothly and reduce
stickiness in processing.

Calcined clays, such as Polyfil 70, Polyfil 80 and Polyfil 90, are brighter than most water-washed clays,
offering excellent processing and limited reinforcement. They impart outstanding wet/dry electricalproperties due to the elimination of bound water during the calcining process. Compounds with calcined
clays extrude smoothly and reduce stickiness in processing. These high brightness calcined kaolin clays
are used to extend elastomeric and thermoplastics products, including wire and cable applications.
