RTP Co., Winona, Minn., has come out with a line of rigid and flexible extrusion compounds for electrostatic dissipation (ESD) applications. Use of special extrusion equipment for excellent dispersion of conductive carbon black is said to produce highly uniform conductivity, optimal retention of physical properties, and good surface appearance, even in thin extrusions.
These compounds are available in PVC, TPU, TPE, PC, PE, PP, PS, and ABS. Flexible grades are used in vacuum hoses, ESD tubing, wire and cable, and geomembrane films. Rigid applications can include industrial pipes and ESD packaging sheets.
