Tough Vinyl Elastomers For Cable Jacketing Withstand Harsh Industrial Environments

The compounds are the latest additions to the Flexalloy® range, which consists of proprietary formulations that provide the elasticity and low-temperature toughness of thermoplastic elastomers (TPEs), plus PVC benefits like flame retardancy. The new products are:

● Flexalloy 9616-94 is a high-hardness elastomer that provides crush and impact resistance and UV stability for uses like mining cable, and flame retardance for applications such as industrial Ethernet networks. The compound has a Shore C hardness rating of 73, equivalent to 94 on the Shore A scale, with a maximum continuous operating temperature of 75°C. It exhibits low temperature capability down to -40 °C and an oxygen index of 38%.

● Flexalloy 9617-79 for use in oil drilling and chemical environments contains a specialty plasticizer that—combined with the high-molecular-weight PVC polymer on which Flexalloy compounds are based—provides excellent resistance to oils and chemicals. The 79 Shore A compound has a maximum continuous operating temperature rating of 105 °C and oxygen index of 35%.

“Flexalloy products provide exceptional ruggedness and durability yet are more cost-effective than TPUs and other high priced TPEs,” said Mike Patel, director of marketing and business development for the Vinyl Division of Teknor Apex. “The new 9616-94 and 9617-79 products are the latest in a series of Flexalloy compounds that Teknor Apex has developed to meet rigorous requirements for copper and optical fiber cables in extreme environments.”
