G Series-551LG PEEK Pure Resin Pellets, a special type of PEEK for electric cables and wires, are made of metal-coated wires and cables. They are heat-resistant, radiation-resistant and breakdown-resistant at the same time. The viscosity of the product is controlled by the process, the continuous extrusion of the cable is ensured, the thickness of the coating is easy to be controlled, and the peeling resistance is ensured.
