Abstract
Abstract Nordel can be compounded with a wide variety of fillers. Reinforcing carbon blacks and silicas are required for maximum physical properties. Non-reinforcing fillers may be added to the compounds to reduce material costs. As with other elastomers, vulcanizates containing mineral fillers have lower states of cure. One of the outstanding characteristics of Nordel is its extendability. Compounds with large amounts of carbon black and oil are easily processed and have good vulcanizate properties. Hot masterbatching in the presence of promoters significantly improves processing safety, modulus, resilience, compression set, and electrical properties of mineral-filled stocks. Petroleum oils, including aromatic types, are excellent plasticizers for Nordel. Those containing low amounts of nitrogen bases and unsaturates, as indicated by the Rostler method of analysis, are preferred especially in low sulfur recipes designed for maximum heat resistance. The properties of Nordel vulcanizates suggest its use in extruded goods, hose, belts, coated fabrics, molded goods, sponge, heels and soles, wire insulation and jacketing, and tires.
