The Polymer Additives Division of Ferro Corp, USA, has introduced two non-lead heat stabilizers for wire and cable applications.
Both Therm-Chek RC 376P and Therm-Chek RC 377P are calcium-zinc powder stabilizers designed to replace tribasic lead sulphate in general purpose wire and cable jacketing applications. The mixed-metal compounds are said to offer environmentally compatible alternatives to traditional lead stabilizers. Both products are stated to have specific gravities that are less than one-third that of tribasic lead sulphate, the most commonly used lead stabilizer (which has a specific gravity of 6.4). Their correspondingly lower densities yield a lower ...
