Electrical resins join and repair cable, replace cable jackets, insulate and provide a moisture barrier. They form strong bonds and have high tear strength to prevent cable joints from tearing. Electrical resins can consist of various compounds, including epoxy and polyurethane, and are generally flame retardant and resistant to high temperatures, oil and corrosion. While epoxy electrical resins are mainly used for insulating and protecting cable from moisture and contaminants, polyurethane electrical resins are typically used in potting cable junction boxes and creating cable joints. Electrical resins can be used in high-voltage and low-voltage applications, as well as in a variety of temperatures without cracking. Resistant to chemicals and ultraviolet (UV) light, electrical resins are strong, durable and versatile.
