Polyfil® WC
is an organo-functional calcined kaolin clay used in wire and cable and other thermoplastic applications. It is designed to reduce water vapor transmission, yields excellent wet and dry electrical properties, and also long-term stability in EPR and cross-linked polyethylene. Calcined clays have low conductivity due to the elimination of bound water during the calcined process. Compounds with calcined clays extrude smoothly and reduce stickiness in processing.

Polyfil® WC-426
Fine particle size vinyl-functional calcined clay for outstanding wet electricals and long term stability in wire and cable applications.

Polyfil® DL
Fine particle size vinyl-functional calcined clay for outstanding wet electricals and long term stability in wire and cable applications.

Polyfil® DLX
is a large particle size, very high aspect ratio, delaminated clay that reduces gas and vapor permeability. It is a type of water washed clay which is processed to have a high aspect ratio. Large and platy particles provide effective barriers to gases and liquids and help improve gas retention properties in rubber inner liners and other applications. In the delamination process, KaMin processes kaolin particles (stack of platelets, as they are found in nature) into special wet-grinding, attrition mills. The clay stacks are reduced to thin kaolin platelets.

Polyfil® HG
is an ultra-fine particle size, moderate brightness water washed kaolin clay. It offers acid resistance, barrier properties, reinforcement, neutral ph, and extremely low crystalline silica and salt content.
