BURGESS 30®is a partially calcined clay used extensively in PVC compounds to improve insulation resistance. BURGESS 30® exhibits excellent dispersion and color uniformity.

BURGESS ICECAP K® is an excellent extender for TiO2 in coatings where a high hegman grind is required. The low screen residue, due to the removal of agglomerates, makes it a leader in the field of calcined kaolins. Applications include wire and cable, molded and extruded rubber and plastic products. BURGESS ICECAP K® has good electricals, low compression set, and low water absorption.

BURGESS 30P®is a flash calcined median particle size clay used extensively in PVC compounds for improving electricals. BURGESS 30P® exhibits low specific gravity and excellent color. Lower pound/volume cost results with the lower specific gravity kaolin.

BURGESS NO. 20 is a fine particle size, medium brightness hydrous kaolin clay. Burgess NO. 20 is the neutral pH version of Burgess NO. 60. BURGESS NO. 20 is used in jacketing layer of wire and cable insulation compounds, rubber roll covers, polishing compounds and concrete curing compounds.

BURGESS KE is an uniquely processed silane modified anhydrous aluminum silicate designed for use in EPR, EPT, crosslinked polyethylene and polyester systems. BURGESS KE is a very pure, high brightness, low residue, calcined kaolin with a surface that has been chemically transformed by the carefully controlled reaction of an organofunctional silane. This surface conversion permits direct reaction with compatible polymer matrixes in the presence of a peroxide yielding excellent dispersion with minimum work required. The evidence of clay/silane/polymer interaction is demonstrated by increased physical properties such as tensile strength and compression set. KE exhibits excellent wet and dry, initial and long-term electrical characteristics.

BURGESS 2211 has been specifically developed for use in mineral filled nylon applications. Burgess 2211, amino silane treated Icecap K, offers dramatic advantages in physical properties compared to untreated fillers. Low warpage and high impact strengths are key advantages.
