Power cable manufacturing, materials & machinery PVC elastomers for power cable applications up to 1,000 volts For low- and medium-voltage applications, Flexalloy ® PVC elastomer compounds are said to withstand high heat and extreme cold more effectively than standard flexible PVC and are considered cost-effective alternatives to olefinic and styrenic thermoplastic

elastomers (TPEs). Examples of power cable applications recommended by Teknor Apex include flexible cords, welding cables, and mining cables. Flexalloy compounds are proprietary products available only from Teknor Apex and manufactured in identical formulations at the company’s plants in the US, Singapore, and China. Grades with Shore A hardness ranging from 65 to 90 are available for both insulation and jacketing, and all can be extruded at high speeds and in a variety of wall thicknesses on standard equipment. With a low-temperature brittle point of –50°C and a high temperature rating of 105°C, Flexalloy compounds stay flexible under a very wide range of conditions. They withstand extreme cold, searing heat, and wet environments without cracking, softening, or compromising the integrity of the cable. Other notable properties include high levels of toughness, abrasion resistance, and resistance to oil and chemicals. Like olefinic and styrenic TPEs, Flexalloy compounds are not only flexible but also truly elastic and provide a rubber-like look and feel. At the same time, Flexalloy products surpass many widely used olefinic and

styrenic TPEs in tear and tensile strength and resistance to flexural fatigue. In addition, they retain valuable advantages of all PVCs, including much better resistance to oils and fuels, significantly greater flame retardance, and wider formulation versatility.
